Monorail Mumbai noisier than predicted

The Mumbai Metropolitan Region Development Authority (MMRDA) had promised that the noise level of the monorail will be between 65 to 85 decibels (dB), but a survey conducted by an expert showed that it is over 90dB.

Exactly a year ago, PRK Murthy, chief of transport and communication, MMRDA, had said efforts were being made to further reduce the sound levels of motor. On the contrary, when noise activist Sudhir Badami checked the sound level, he was surprised to find that it was above 90dB.

“The noise level inside the cars is more than 93dB. MMRDA had claimed that it will be a silent or quiet mode of transport,” said Badami.

The Brihanmumbai Electric Supply and Transport Undertaking (BEST) buses create noise level of close to 95dB. As per the World Health Organisation, the safe sound limit is 85dB, anything above this will result in irreversible noise induced hearing loss. According to medical practitioners, loud noises above 80dB can seriously affect the development of hearing ability in young children. Due to the design and technology of the monorail it can take sharp turns. In Mumbai, it has been constructed in the residential areas having narrow roads. Those residents living along the corridor will surely have a tough time. “In crowded sections, people residing alongside will be subjected to noise at every five minute intervals,” added Badami.

Residents from GB Road Thane demand sound barriers

THANE: Thousands of families living along the busy Ghodbunder Road are having sleepless days due to the extensive noise levels, especially due to heavy vehicles. Some are also complaining about sleep disorders, general irritation and health disorders.

Seeking relief from the pounding noise of containers, trucks and honking of cars, more than 5,000 residents from Rutu Park and Devashree Gardens have joined hands to demand immediate installation of sound barriers and other environmental protection.

In fact, the noise levels recorded by the TMC from the terrace of Rutu Park in the first week of January revealed shocking decibels all through the day. ”The sound level touched 71.5 decibel in the day, which is way above the permissible level of 55 decibel. At night, the flow of heavy traffic increases and the volume of noise recorded is around 66.5 decibel as against the 45 decibel that has been set by the pollution control department of the TMC,” said a resident of Rutu Park, Rajan Vyawahare.

He added that they have taken up the issue with the Maharashtra State Road Development Corporation (MSRDC), Mumbai Metropolitan Region Development Authority (MMRDA) and Mumbai Entry Point Ltd (MEPL), which looks after the maintenance of bridges on Ghodbunder Road. They have demanded that a sound barrier wall must be installed with immediately effect for the convenience of residents.

”The authorities have put up such sound barriers at BKC, Powai and Dahisar as a protection from the noise from the vehicles speeding on the road. We are asking them to install the same barriers here as it will help reduce the deafening noise,” he said.

Vyavahare said that while containers, trailers and cars create rumbling sounds, ambulances are the noisiest due to their loud sirens. ”Children wake up with a fright and elders have sleepless nights because of the noise. However, it could be reduced if the roads are properly maintained, especially at the slope of the flyover. We have had discussions with the state officials on this issue. The case will also be taken up by top bureaucrats from the MMRDA next week. We are expecting that they come out with a permanent solution to the problem,” he added.

Taiwan highway to get noise barrier to protect birds

Noise barriers will be installed on a section of central Taiwan’s Provincial Highway 61 to protect migratory birds traveling in the area. The highway’s construction has stalled for decades over disputes between the country’s highway bureau and environmental groups, reports our Chinese-language sister paper China Times.

The construction of the highway that connects New Taipei in northern Taiwan and Tainan in the south has been delayed for two decades due to concerns from environmental groups that it will have a negative effect on migratory birds and the ecology of the coastal area. Nearby residents are also opposed to relocating the highway to an inland area due to the noise and pollution it would cause there.

After Wednesday’s conference, Taiwan’s Environmental Protection Administration decided to add curved noise barriers to a 3km-long section of the 13km-long highway. The decision was made after both environmental groups and the highway bureau reached a consensus, after years of opposition on the issue. The group asked the bureau to keep the highway 300 meters away from seawalls and add tunnel-like noise barriers on a section in Fangyuan in Changhua to prevent birds hitting cars and vice versa, as well as reducing noise and light influencing migratory birds in intertidal zones.

The highway bureau has redesigned a section of the highway close to wetlands in Fangyuan, Fubao and Hanbao in Changhua where the highest number of migratory birds were found in 2008. The section has been moved 200 to 300 meters inland to an area full of abandoned fish farms. The dome-like noise barriers set to be installed will add another NT$300 million (US$10 million) to the cost of the highway.

The highway will be the first in the country to incorporate noise barriers specifically designed to protect birds after it is completed in 2019. Environmental groups pledged to continue monitoring the highway to ensure the barriers reduce the effect of the highway on migratory birds.

When students school in noise environments

From time to time, the Lagos State government, through established agencies such as the Lagos State Environmental Protection Agency (LASEPA), swoops on religious organisations, music studios and music shops found to have run afoul of the state’s laid down rules on noise pollution, yet a certain category of residents – school students – is believed to be the most affected by noise pollution often experienced around their schools.

A journey round parts of the Lagos metropolis, as made by Sunday Tribune, showed that the locations of many primary and post-primary schools share boundaries with noisy markets, industrial areas, roads, religious centres, among others.

For instance, a public primary school at Kola area of the Lagos-Abeokuta Expressway was found to be sharing boundary with the noisy Kola Market and also had a stagnant and open gutter at its entrance. Unfortunately also, the school was built only meters away from a high-tension power line.

Within the same area, two schools, Tomia Senior Secondary School and Alagbado Junior Secondary School both of which share the same premises, were found to be located quite close to a section of the Kola Market where Compact Disc (CD) sellers busied themselves as they advertised their wares through noisy music from their shops.

Many of such traders were found to have large speakers placed directly in front of their shops. And apparently in a bid to outdo one another, each trader made his speakers’ noise level higher than others.

Also at Ogba area of Ikeja, the walls, roof and windows of a school located on the dusty Wempco Road were observed to have been covered with dust produced as a result of a road expansion project which has been ongoing for about two years.

It is impossible to learn with the noise—Student
One of the students of the earlier mentioned school at Kola, Ayo Akindele, when asked how he felt learning in a noisy environment, said noise from a grinding machine or from one of the numerous CD shops around had become a menace that often disturbed students while lessons were going on.

“Often, the noise disturbs us a lot. You can imagine a situation whereby a student is trying to understand what his teacher is trying to say, only for such a student to be jostled by a loud music close by. This happens from time to time, and no matter how we try to ignore it, it will always be there. It is impossible to learn here,” Akindele noted.

Continuing, he stated that “I was distracted on a particular instance. It was a popular hip-hop song from one of Nigeria’s new acts that was coming from one of the shops. I had no idea the song coming from my lips while the lesson was going on was already getting out of hand, as I had already started singing a bit more loudly. It took a firm nudge from a friend sitting close to me to rouse me back from my dreamland. Had the teacher noticed this, I could have doubtless landed in a big trouble.”

According to experts, noise, which is generally known as any unwanted sound, is believed to have a lot of deleterious health effects on the society, especially on young people.

While in extreme cases, noise is said to have the potential of causing hearing impairment, and hypertension; it is also known to be a main cause of annoyance, and sleep disturbance, to all categories of people.

Commenting on the effect of noise on a learning environment, a psychologist and social behaviour expert, Mrs Feyisara Amos-Miller, told Sunday Tribune that apart from serving as a major source of distraction, noise from markets, moving vehicles, religious centres and other sources, hampers the ability of students to concentrate in the long run.

“When exposed to noise for a very long time, hyper-active children tend to become more active and even quiet children tend to lose touch with their sensitive nature. Generally, the existence of a noisy environment does not bode well for learning,” she stated.

Explaining how noise affects the cognitive development of students, particularly those in their early years, Mrs Amos-Miller insisted that when regularly exposed to levels of noise that interfere with speech, young children could eventually they develop speech or reading difficulties.

She further disclosed that aside the mentioned effects, elevated noise levels, especially those associated with loud music and industrial activities, create stress and stimulate aggression and other anti-social behaviours.

“We are taught that when children learn in noisy classrooms or are made to daily experience noisy situations, they end up having more difficult time understanding speech than those who learn in quieter environments. Children’s mental development should never be taken for granted because they continue to develop their speech perception abilities until they reach their teens,” she added.

UNESCO’s requirements for siting schools
According to the United Nations Educational, Scientific and Cultural Organisation (UNESCO), some of the important aspects of school management that must never be compromised include school location, area per space, school size, as well as school buildings. Others are presence of acoustic facilities, libraries, sports facilities, among others.

But also importantly, UNESCO’s standard stipulates that a minimum distance of 183m must be maintained between a school’s location and a bar.

Sadly, however, not only are many schools in Lagos, as earlier revealed, located close to busy and noisy markets, many of such markets often turn out to be where alcoholic beverages are sold.

In his own view, an educationist, Mr Omotere Tope, in his recent report entitled: “Influence of School Environment on the Academic Performance of Secondary School Students in Lagos State,” said factors such as school facilities, class size, school location and planning are known to have direct effects on the academic achievement of secondary school students.

Much of the problem has been blamed on poor regard for land use planning by successive governments. This view was shared by a seasoned town planner and ex-chairman of the Nigerian Institute of Town Planners (NITP), Mr Moses Ogunleye, in an interview with Sunday Tribune.

“There is big challenge with regards to land use planning in Lagos state. Most of what we have are cases of sporadic developments based on one-man decision or one-investor decision, which are basically for business purposes.

“The ideal way to plan is build in accordance with what is called complementary building. This describes a situation whereby, for instance, a school complements a library; a market complements a motor park, for effective traffic management. But what we have is a situation whereby it is either industries go to meet schools or schools meet industries,” said Mr Ogunleye.

When explaining that though it is not always a bad idea for schools to be sited close to industrial areas, he insisted that such must only be encouraged if such industries do not fall within the class of industries called ‘heavy industries.’

He however insisted that when schools are thus located, provisions must still be made for ‘buffers,’ which he described as some sort of natural protection that can come in the form of thick bushes or other natural vegetation meant to protect schools located close to industrial places.

While insisting that the problem did not recently emerge, he suggested that the only way forward is for a synergy to be created between the state’s ministries of education and environment.

“If unapproved developments spring up around schools, then questions must be asked from appropriate authorities.

“Some of such schools are products of political reasons, whereby one decision maker would just wake up and decide to set up a school at an unapproved place. We know instance when a governor-to-be would promise to build a school without anyone bothering to know if such a school will be built on an approved land,” he remarked.

However, the Lagos State government has repeatedly indicated its readiness to ensure that all public schools in the state are kept in the best shape possible so as to make them conducive for students to learn.

Speaking recently, the Commissioner for Education, Mrs Olayinka Oladunjoye, remarked that provision of infrastructure in public schools was an ongoing process and that more schools would be furnished in order to cater for the ever growing demand for learning.

Similarly, the General Manager of LASEPA, Adebola Shabi, has pointed out that the agency was committed to ensuring that all forms of pollution, including noise, and other things that pose as nuisance to the environment will be reduced to the barest minimum.

“Noise is harmful to humans when above certain decibel level, therefore, LASEPA is willing to work with all organisations and most especially all residents of the state to ensure that noise pollution is reduced to the barest level in the state,” he said.

Noisy Thailand ?

I am 90 years old and have been coming to Thailand for the last 20 years. I love the country, the climate (in your winter) and the people, and of course the food. But I hate all the very unnecessary noise. The motorbikes with the baffles knocked out, or the very old ones, they do it deliberately revving up to show off how powerful the bike is, which it is not at all. As an ex. motorcyclist the really fast ones are no more noisy than a big car. They often do this at 3 or 4 or 6 in the morning. Why can not the police confiscate these bikes as they can do in England?

Then there are the ambulances at 5 in the morning with no other vehicles on the road blaring the sirens, travelling quite slowly. Fireworks! OK on a particular night up to a reasonable hour, but hawkers sell them on the beach, and those there who have had a few with no thought for anyone else let them off at all hours, any night. Only bangers that make the biggest bang.

Then worst of all are the small bars, with a hi fi with a loud penetrating bass which is all you can hear that’s pounding away non stop until well after 3 in the morning. So easy for a patrol to call and shut them down or turn the so call music down at midnight. I go to bed between 10 & 11.

Finally cars or other vehicles with hi fi systems so loud you can hear them coming from a mile away. Also, so many loud speaker vans mostly advertising in Thai. Could they also not be reduced, limited and controlled? The only thing we get in the UK is police sirens, we never seem to get those here.

I’m sure this can make some people have second thoughts about coming back to the Land of Smiles. We old uns have the most money and stay the longest.
