People living 8 km away from a music festival complain about noise

The weekend’s S2O the city of Hong Kong Songkran Music Festival took place at the Central Harborfront.

Eight noise complaints about the weekend’s festival at the Central Harborfront have been reported to Hong Kong environmental authorities, and some residents in Wong Tai Sin and Tsz Wan Shan, eight kilometers away, have complained about loud music disturbing them.

The S2O Hong Kong Songkran Music Festival’s organizers announced on Wednesday that they had hired personnel to measure noise levels at various locations throughout the venue, and that they had “no serious exceedance” noted during the entire event.
A festival representative stated, “During the event, the measurements were reported to the Environmental Protection Department every hour.”

“During and after the event, the organizer maintained close communication with the Food and Environmental Hygiene Department and the police.”

US singer Pauline Herr, Moldovan song producer Andrew Rayel, and South Korean DJ NewJeansNim were among the performers scheduled for the two-day festival on Saturday and Sunday.

On social media, some residents of the communities across Victoria Harbour in Wong Tai Sin and Tsz Wan Shan claimed to have felt vibrations from loud music on both nights.

Others claimed to have dizziness and ear pain.

“I can still hear the noise even though all the doors are closed,” a Facebook user stated over the weekend. This is absurd.

Another internet user claimed he had to take painkillers because the noise was so loud.

Some other people online questioned the range of sound waves and why the music was only audible to those living in Wong Tai Sin and not to those living throughout the Kowloon peninsula. There are 8 km in a straight line between Central and Wong Tai Sin.

According to the Environmental Protection Department, it kept in touch with the organizers of the various outdoor music events held on the Central Harborfront and “paid close attention to various outdoor music events.”

A representative stated, “The loudspeaker volume has to be adjusted if excessive noise is detected from an event.”

He said there was no noise disturbance discovered during inspections on Saturday and Sunday at the Tsim Sha Tsui promenade across the harbor and close to City Hall, respectively.

Although the department promised to investigate the complaints, it was unable to determine if the complainants were from Tsz Wan Shan and Wong Tai Sin.

The department verified that the festival organizer had submitted an application for a temporary license to operate as “places of public entertainment.”

The license requires that the event’s organizers keep an eye on noise levels in areas where people are sensitive to noise, modify the loudspeaker’s direction to avoid nearby residential buildings, and terminate the event before 11 p.m.

Police said they were unable to identify the source of multiple complaints they had received on Sunday night regarding music and noise disturbance.

Low-frequency noise, according to chartered mechanical engineer Lo Kok-keung, can travel eight kilometers. In addition, he mentioned that Wong Tai Sin and Tsz Wan Shan were higher up on the Kowloon peninsula than other areas.

Locals in Tampines complain that noisy chickens keep them awake at night.

The loud hens in a nearby park have been causing some Tampines residents to lose sleep.

According to two locals, the hens at Sun Plaza Park on Tampines Avenue 7 have been crowing early almost every day, keeping the residents’ sleep disturbed, as reported by Shin Min Daily News.

There are roughly eight blocks of HDB apartments near the park, according to a Google Maps search.

The Chinese daily was informed by a disgruntled resident, Chen, 38, that the issue began in December 2022 and that he hears the chickens crowing at around five in the morning.

“I grew up in the neighborhood, and this kind of issue never existed before. I think there are too many wild chickens being produced.”

Another resident, 70 years old, went by the surname Ji, saying the noise from the crowing of the chickens frequently wakes her up at 4.45 a.m. and keeps her awake.

“I’m having trouble sleeping, and it gets worse every day. My granddaughter has to go to school, so I usually get up at six in the morning,” she continued.

Upon visiting the park on Monday afternoon, May 27, a Shin Min reporter observed that numerous chickens were loudly crowing and flying up and down from the trees.

Chen reported that no one has been feeding the birds at the park, and they just appeared out of nowhere.

After voicing several complaints to the Tampines Town Council, he received an email confirming that the council was collaborating with NParks to securely relocate the chickens.

“I believe the authorities have taken action, including relocating the chickens, but it seems to have little effect,” he stated. “I hope the problem gets resolved without harming the chickens.”

AsiaOne has requested a statement from the Tampines Town Council.

Typical view in Tampines
For a long time, Tampines has been home to hens that are allowed to roam freely.

In 2018, the Straits Times reported that a number of locals had voiced concerns regarding the cacophonous clucking of chickens in the garden area situated on Blocks 266 and 267, Tampines Street 21. After that, the Agri-Food and Veterinary Authority collaborated with the Tampines Town Council to move a few hens.

As per a May 2023 report published by The Straits Times, NParks has received over 600 submissions regarding wild chickens until the time of publication. In 2021, there were 950 reports received by town councils, government agencies, and the Ministry of National Development—more than three times as many as in 2017.

According to The Straits Times, there have also been reports of free-ranging chickens outside of Tampines in places like Pasir Ris, Kembangan, and Bukit Merah.

When the second runway at Hong Kong International Airport opened, there were complaints about aircraft noise. – from the SCMP archive

Yesterday saw the opening of Chek Lap Kok’s second runway, amidst threats of protests from Tsuen Wan locals who say they were not informed about the nearly 80 decibel aircraft noise.

Albert Chan Wai-yip, a member of the Tsuen Wan District Board and convenor of the Aircraft Noise Concern Committee, stated that over 150,000 people, or half of the city’s population, live beneath the second runway’s flight paths.

The District Board estimates that aircraft noise from Chek Lap Kok may affect one million people.

However, Alex Au Kang-yuen, acting director of the Civil Aviation Department, claimed the number was “exaggerated.”

The Aircraft Noise Concern Committee reports that following yesterday’s runway opening, noise levels at Allway Gardens and Belvedere Garden were 78 and 77 decibels, respectively.

Yesterday’s readings from the Civil Aviation Department varied from 60 to 66 dB.

Anything above 85 to 90 dB can temporarily impair hearing, which is the safe noise limit.

On May 26, 1999, a Xiamen Airlines aircraft touches down on the Hong Kong International Airport's new north runway. Image: SCMP

There are currently up to 37 flights per hour, seven days a week, taking place at a maximum of 1,000 meters from some heavily populated areas.

Each runway will be able to accommodate up to 40 aircraft per hour by the end of October, according to a spokesman for the Civil Aviation Department.

According to Mr Chan, unrest may result from the disruption of the way of life in the New Territories.

“People can do incredibly unreasonable and crazy things when the economy turns sour and emotions are unstable,” the speaker said.

Depending on the direction of the wind, the group wants aircraft to change their route.

Mr. Chan stated that petitions would soon be submitted to the Civil Aviation Department.

Chen Ying-sung, 71, an Allway Gardens resident, said the police were underreporting noise levels.

He measured the noise pollution on his building’s roof with Mr. Chan yesterday, and the results showed that it reached 78 decibels.

Mr. Chan remarked, “I can’t hear the television when it’s the loudest.” “I’m concerned about the situation once flights [on the second runway] start operating nonstop in August.”

At a press conference on May 27, 1999, Simon Li Tin-chui of the Civil Aviation Department talks about the aircraft noise produced by the two runways at Hong Kong airport. Image: SCMP

According to a spokeswoman, the Civil Aviation Department has met with Tsuen Wan and 12 other district boards on multiple occasions. She stated that residents would not receive any compensation.

The Advisory Council on the Environment’s chairman, Peter Wong Hong-yuen, announced that the group would ask to be briefed with the Civil Aviation Department and the Airport Authority.

“The proposed flight path needs to be examined; even a one-mile difference can have significant effects,” he stated.

At 10.30 a.m. on Dragonair flight KA807 from Shanghai, the first passenger aircraft to land on the new northern runway was made.

Loud and inappropriate noise The Uttarakhand government forbids filming reels and videos at Char Dham

The Char Dham shrines are 50 meters or less from the Uttarakhand government’s ban on filming reels and videos.
This is a long overdue decision because the video producers engage in behavior that might be deemed improper for a place of sanctity in addition to obstructing pilgrims’ paths and causing delays in line.

Chief Secretary Radha Raturi of the state stated, “Some people record videos, create reels, sing, play music, and do other things that hurt other people’s religious feelings. Having a cell phone and making calls with it is not forbidden. However, it is forbidden to play loud music, create reels, or cause any other disturbance on the temple grounds.

When a 60-quintal “Om” figure was erected at Kedarnath Dham in 2023, there were protests. Since then, it has become a location for selfies. Many people think that the attention on these things ruins the quiet reflection and devotional feelings associated with visits to sacred sites.

In a review meeting, the state’s chief minister, Pushkar Singh Dhami, also urged all VIPs to postpone their yatra beyond May 21 due to the influx of pilgrims.

Furthermore, letters warning against unregistered yatris attending the yatra due to chaos have been sent to all states. Only online registration is available, and the government has asked that those who have registered arrive in Dham by the deadline. Before the yatra, health examinations are required, and people with co-morbidities, like heart conditions, are asked to disclose this information.

The increasing practice of creating reels—at times in awkward positions, using loud voices, etc.—has raised concerns at other houses of worship as well. For example, there have been numerous incidents of locals in Ayodhya beating up people who are bathing in the Sarayu, at the ghats, and creating reels to songs that are offensive. “There should be respect for the religious and spiritual sanctity of holy places,” stated Mahant Raju Das.There are plenty of other places to visit if your only goal in visiting is to view the pictures, videos, and social media posts. There are about thirteen locations for selfie sticks in Ayodhya, and Chief Minister Yogi Adityanath was notably pictured at Lata Mangeshkar Chowk snapping a picture of himself using a phone on a selfie stick.

On May 10, the Char Dham yatra was declared open. Over 3.3 lakh people had visited the shrines as of Thursday.

Drilling holes in the wall, tapping the floor, or pulling furniture at night for ten years

SINGAPORE: A resident has had enough of her noisy upstairs neighbor of ten years and has taken to social media to seek guidance from other Singaporeans.

The internet user stated on Monday, February 26, that for ten years, “literally every single day, either they are drilling the wall for more than thirty minutes (don’t know drill what also) or knocking the floor with a walking stick and dragging furniture at night.”

Although it’s manageable, there are moments when it becomes unbearably loud.

I went upstairs one night to confront them, and when they didn’t answer the door, they kept knocking on the floor with what sounded like an old-fashioned metal hollow walking stick. That’s how I knew it was a walking stick.

Every time it gets really loud at night, I also call the police, but the noises only stop for a few days before they start knocking and dragging again.

After knocking and getting no response, I’m at a loss for what further action to take. Because my estate is close to IMH, the only conclusion I can think of is that the person may be a patient there.

I’m not sure what I should or can do with that knowledge. Is there anyone who can offer advice on what to do? Asking, “Legal or not-so-legal ideas accepted,” the writer continued.

Remarkably, the post inspired a few more people to share their own tales of “nuisance neighbors.” Numerous people related their personal experiences of coping with neighbors of this type.

Some agreed that a confrontation was necessary, while others went so far as to involve the authorities by calling them. Some countered that these actions didn’t offer long-term fixes.

One resident who had experienced noisy neighbors firsthand wrote, “I feel you.”

“My neighbors next door have noisy kids upstairs as well as persistent floor knocking.” It is possible that they have a platform in their room because every time they run, jump, or walk on it, a hollow sound is heard.

Not something I could handle once at midnight. went up and reprimanded them angrily. The 15-year-old boy denied knocking; when his mother arrived at the door, I reprimanded her as well.

Since then, there has been some but not much less noise. I had previously provided HDB with feedback, but it was also ineffective.

Another said, “We left notes for this specific household.”

“I spoke with them directly and gave them my contact information to let them know when it became too loud.” It was effective for a while, but then it got worse.To cut a long tale short, we made several calls to HDB, the town council, and the police.

When we got our neighbors together, we noticed that they were all growing irritated and they also reported this family. Then we repeated the process, reiterating our earlier reports (i.e., telling HDB that everyone had called the police several times and that this was the last straw).

The next day, I got a call from HDB, who sounded like an intern reading from a script and didn’t know how to assist. However, we never had any problems (with) this family again after that day.

How the construction industry is becoming quieter thanks to a Hong Kong start-up’s use of recycled plastic

  • Acoustic Metamaterials Group produces noise-cancelling barriers for the construction industry using recycled plastic.
  • The Green Tech Fund of the Hong Kong government provided US$435,000 to the startup’s founder so they could test technology for producing more noise-efficient products.

The goal of the smart materials and acoustics company Acoustic Metamaterials Group (AMG), situated in Hong Kong, is to increase the utilization of recycled plastic in the construction sector in order to assist in reducing noise pollution and the industry’s carbon footprint.

Chen Shuyu, the founder and director of the start-up, claims that their manufacturing technology can recycle plastic waste to create noise-control products that have an acoustic performance that is on par with or better than that of conventional materials like rockwool, fiberglass, and foam.
“Recycled plastic could replace nearly all types of materials used for acoustic purposes in buildings and in noise-cancelling barriers,” stated Chen. Chen is scheduled to participate in a panel discussion on construction at the GreenTech Summit on Monday, which is a part of the government-organized Hong Kong Green Week.

By altering the structure of solid surfaces like plastic, metamaterials can achieve sound absorption comparable to or even greater than that of conventional acoustic materials without the need for additional components, according to AMG’s product catalogue.

Chen added that this lowers the overall manufacturing cost. The recycled plastic is gathered from factories in mainland China where AMG’s products are made.

AMG was established in 2014 in Hong Kong, and the company claims that its products are used commercially in a variety of industries, such as consumer electronics, automobiles, hi-fi and smart wearables, construction, electrical and mechanical systems, and home appliances.

The government’s Green Tech Fund awarded HK$3.4 million (US$435,000) to Chen’s research and development platform Lumi method in 2022 so that it could test its manufacturing method for further high-efficiency, noise-absorbing materials made from recycled plastic.

The Green Tech Fund was established in 2020 with HK$400 million from the Hong Kong government to fund research and development projects that advance the city’s decarbonization efforts and enhance environmental advantages.

AMG can produce 200,000 square meters of metamaterials annually, part of which are derived from recycled plastic.

Developers in Hong Kong have been using AMG’s road and noise barriers at development sites since 2020. Additionally, China, Japan, the EU, and the UK are recipients of AMG’s exports.

According to Chen, the company wants to use more recycled plastic in the production of noise-cancelling goods for use in road barriers and construction.

He declared, “We are the leaders in [promoting] this concept.”

Does the noise grow with the city?

Does the noise grow with the city?

Bangkok City Plan Revision is underway.

The Thai  Department of City Planning and Urban Development has announced a plan to review and revise the city plan of Bangkok to be in line with the changing conditions and environment of urban development. It was present in the last year of 2023 when new metro and sky train lines were started to be used, giving citizens not only in central Bangkok to access public transport and travel across the city. The new Bangkok city mentioned an opportunity to change the restrictions of land use for some areas. Not only expanding the density of residential zones but also allowing some new areas to be developed e.g. for commercial, while still maintaining the conservation zone for agricultural zones as well as Thai art and cultural zones. While the city seems to be growing, what else may arise along with it behind the scenes?

                News and articles are reporting cases where citizens are disturbed or annoyed by noise (Noise pollution destroying condo life). Statistics also show a trend of increasing numbers of noise complaints and becoming the first-place compliant source in 2023 (Report of complaints of the 3rd quarter, year 2023, Office of the Prime Minister). Noise pollution can be caused by many events and sources, for example, road traffic noise may be one of the major causes in a dense city like Bangkok with a population of more than 5 million people. Imagine the road keeps developing and the population grows denser, more people may be affected by noise pollution without a city noise study to plan a noise control strategy.

                City noise mapping has become a well-known tool used to study the noise exposure of the residents across the city and help governments plan new strategies for noise control, land use planning, or develop new building and housing laws. It is presented that there are noise monitoring stations located in various areas of Bangkok, some station shows that the level does exceed the recommended noise level (Online noise monitoring system from the Pollution Control Department). The monthly noise level report is also available on the PCD website (Noise Monitoring Report from the Pollution Control Department).

Sound planning and noise mapping tools nowadays can connect to the GIS database. Since the Bangkok GIS database is available, the city of Bangkok can be imported directly into the noise mapping software using modelling software such as SoundPLAN. The model can be verified to the real data from the PCD noise monitoring system across Bangkok. The software can also calculate the noise level without conducting an onsite measurement. For example, to calculate road traffic noise, the software can do the calculation using the rate of cars per hour, the mean speed, and the road surface type. Online Bangkok Risk Map (Online Bangkok Risk Map, BMA) is also a great example of using GIS and presenting various data on the Bangkok city map, allowing citizens to observe the situation in their area. It is possible to create a city noise map using a similar method to these maps.

                As it is announced that the current stage of Bangkok City Plan Revision is already underway in phase 1 of surveying and analyzing relevant data, the online website is still open for public opinion until 29 February 2024 (PLAN FOR BANGKOK). As an acoustic consultant, we hope to see people express their thoughts on noise and wish that it will be recognized as one of the topics that should be concerned for citizens’ health and well-being alongside other pollution.

Authorities at Mall of Asia discover no significant infractions of the noise pollution or parking space limits

Authorities such as police and mall developers present their mutually agreed-upon short- and long-term traffic congestion relief measures to the Karnataka High Court.

The management of the mall, the city police, and other government agencies have mutually agreed to implement short- and long-term measures to ease traffic congestion around the mall at Byatarayanapura on Ballari Road in the city, as there have been no major violations found regarding the use of the parking area or noise regulations by Mall of Asia.

Following three rounds of deliberations, held as recommended by the court earlier, to find solutions for traffic congestion caused by mall visitors’ vehicles and to reduce noise level, the long- and short-term measures were submitted before the Karnataka High Court on Friday.

As of right now
The court was told that the temporary measures will be implemented for a period of 15 days starting on January 6 on an experimental basis in order to evaluate their effects.

Judge M. Nagaprasanna, who heard a petition filed by the mall’s management company, Sparkle One Mall Developers Pvt. Ltd., ordered all parties to prolong the mutually agreed-upon action plan and postponed the next hearing until January 30.

The petitioner-company had contested the validity of the prohibitory order issued by the city Police Commissioner on December 29 under Section 144 of the Cr.PC. On December 31, the court made it clear that the order would not prevent the mall from opening for business or allowing the public to enter.

Noise Level
The developers have agreed to reduce the noise level to the allowable limit. According to the proceedings of the deliberations held, the Karnataka State Pollution Control Board had found that the noise level around the mall measured at 67.61 dB L.Aeq (avg), as opposed to the limit of 65 dB L.Aeq (avg) during the day for commercial areas.

The Bangalore Development Authority has approved the development plan for 2,241 residential units, retail commercial spaces, office spaces, and multiplexes on an area of approximately 65 acres, according to the Bruhat Bengaluru Mahanagara Palike (BBMP). The plan also includes a 13-acre mall.

A total of 3,488, comprising 2,029 (retail/commercial), 271 (multiplex), and 1,118 (office space), parking spaces are required. 2,324 parking spaces must be provided in total for the area (commercial retail space and multiplex) for which a partial occupancy was granted. According to the BBMP, surface parking must be allocated 5% of the entire development project area during the meeting.

Upon inspection, the BBMP discovered that 2,599 car parking spaces, including stack parking, were provided in accordance with standard procedure and that both basements were utilized for parking as intended. But according to the BBMP, some of the 225 surface parking spaces that were supposed to be used were instead used for landscaping.

Parking costs for motorbikes
The traffic police’s recommendation to lower the two-wheeler parking fee in order to incentivize people to park inside the mall’s parking area rather than haphazardly on nearby roads has been accepted by the mall developers. All vehicles, including taxis and autorickshaws, must enter and exit in accordance with the traffic police’s recommended traffic circulation plan.
