Noise levels in city above standards

Deepa H Ramakrishnan

The noise levels in the city constantly remain above the prescribed standards, according to data recorded under the National Ambient Noise Monitoring Network of the Central Pollution Control Board.

The noise levels have been monitored round the clock at Triplicane, Government Eye Hospital in Egmore, Guindy, Perambur, T.Nagar since March. Near the Government Eye hospital, which has been classified as a residential area, on Tuesday the maximum recorded sound during 24 hours was 67 decibels (A) and on Monday it was 67.2 dB(A).

A, in dB(A), denotes the frequency weighting in the measurement of noise and corresponds to frequency response characteristics of the human ear. The standard for residential area is 55 dB(A) during the day time and 45 dB(A) at night.

At Guindy, identified as a commercial area, the daily maximum noise levels are constantly above 77 dB(A). Triplicane too has been classified as a commercial area and the figures hover around 69 – 70 dB(A). On certain days like Sunday, it touched 76.7 dB(A). The noise monitoring station in Perambur, an industrial area, recorded 70.6 dB(A) on Tuesday and 69.8dB(A) on Monday.

M.L.Munjal, honorary professor, IIS, Bangalore, also the Chairman of the National Committee for Noise Pollution Control, said efforts must be taken to inculcate road discipline among motorists and pedestrians.

A citizen has a right to complain about noise that disturbs him.

Are we becoming a nation of noise-makers?

D. B. N. Murthy

“Noise should be seen but not heard,” states one advertisement for window glass. However, we Indians love noise — the more the better! That's the reason why we do not pay much attention given to noise reduction in homes.

An incident of outside noise causing problem to a residential area came up a few years ago. The newly opened high-rise building had installed an air-conditioner. The water used was re-circulated by cooling through a motor/pump. This set off a continuous humming sound that was a source of annoyance to the neighbourhood. A complaint given to the owner of the building was ignored stating that the noise was within limits.

Thoroughly disappointed with such a negative attitude, some of the residents approached the Corporation authorities. Thanks to the investigation work done by the inspector concerned, the owner agreed to install a barrier to contain the sound. Then the noise level reduced considerably much to the relief of the residents, who had suffered for so long.

Traffic noise is one of the sources of noise that affects a householder. He/she has little control over such man-made noise, except taking certain steps to minimise the effect of noise inside. Plants outside, where possible, could cut some of the noise. Blinds and drapes on windows could further act as barriers. It is rare to see a construction, which has proactively taken steps to install noise-reducing steps such as fixing foam boards and other sound absorbing materials inside or outside the walls. That applies to windows, which could have a frame outside that could absorb or deflect sound.

Noise generated inside a house is rarely recognised by someone who has been living along. He/she fails to appreciate the fact that the noise level is high and could have long-term deleterious effects such as loss of hearing or other effects on the human body due to prolonged exposure to noise. There are a few sources of noise inside a house — TV, music system, air-conditioner, washing machine, refrigerator, microwave and so on.

Some of the modern domestic appliances have less noise level. For example, a refrigerator, as it is on continuous operation, makes a buzzing noise when the compressor is activated periodically. The modern refrigerator, especially the compressor, is improved as far as energy and noise level are concerned as compared to the older versions. It would be desirable if the householder pays attention to noise emanating from domestic appliances and seeks advice before buying a particular model. While some noise is unavoidable, one has to look for constant buzz or heavy noise that could lead to long-term effects without one's knowledge.

Loss of hearing is one health hazard which one recognises when it's too late. Personal stereos and cellphones should be used with caution, preferably at reduced sound levels or with hand-held devices and that too sparingly. Another problem are noisy neighbours! We can only appeal to them to tone their TV/music system and talk/laugh less loudly!

Indoor drapes, shades, indoor plants and lower noise domestic equipment are the means to achieve lower noise levels for a comfortable living. A floor could have sound absorbing materials coated to minimise noise when someone walks on it. Sound absorbing material could be fixed inside or outside at strategic locations which could minimise the external noise effect. That applies to noise deflectors, such as barriers and plants that could deflect noise if it is from any specific location.

Noise could lead to health hazards, besides spoiling one's mood when someone seeks quiet and peace at his/own home. The government has fixed a limit of 55 db maximum for residential areas during daytime and 45 db maximum during nighttime, which unfortunately is followed more in the breach than in practice. A citizen has a right to complain about noise that disturbs him. Police could lend a helping hand to shut down loudspeakers beyond 10 p.m. or warn a boisterous party going on next door.

Chennoise – that's who we are
(By Prabha Sridevan)

• Living in Chennai is equivalent to living in a factory – at least in terms of how much noise all the residents are subjected to. Data from the Central Pollution Control Board (CPCB) shows that the noise levels everywhere in Chennai are over 100 dB – more than a typical factory. The average noise level in Chennai is actually higher at more than 129 decibels. It must be noted that pain in the ear begins at 125 decibels. The permissible limit is 85 dB fixed by the World Health Organisation (WHO).

The above is an extract from a newspaper. Maybe we can call ourselves Chennoise? We shout, we scream, we are loud.

We believe in loudness for all seasons. We have devotion and faith blaring from those cone things in every street and you worry whether closing your ears is a sacrilege. In fact, there have been cases in the Madras High Court where petitioners have complained of this noise assault. But Chennai does not care.

We have huge commercial establishments in residential streets, schools in cul-de-sacs, kalyana mandapams in what used to be quiet streets. The offices have noisy generators and neighbours are asked to “adjist” when they complain of the noise. Wedding receptions, of course, must have what is called light music concerts. How is it “light”, pray? Weddings are social occasions too, when we meet friends and relatives, renew bonds. It is just not about the ‘girl’ and the ‘boy’ coming together. But with these huge speakers drowning out normal sounds, we are zonked into silence. This is about dear ones coming together. The story is the same when dear ones depart. From the womb to the tomb, it is a life of audio attack.

But what do you expect? Schools shout. Children warble away into microphones in quiet avenues. People use drilling equipment all the 24 hours repairing their flats with no thought for the elders, the sick, the infants in the neighbouring places. Yes, it is your house and you have the right to set it right. But it is their living space too, they have the right to some peace and quiet. Why can’t we inform our neighbours that we will drill or hammer from, let’s say, 9 a.m. to 3 p.m? We don’t care about anyone else when we raise the noise decibel. So, kids learn that it is all right to be loud and insensitive. And as grown-ups they continue to be loud and forget the virtues of silence.

There are silences and silences. To name some, there is the silence of spirituality, the silence of a learner, the silence of loyalty, the silence of ignorance, the silence of weakness, the silence of cowardice, the silence of reverence, the silence of companionship and even the forced silence. Some are positive silences, some are not. For instance, the silence of omerta imposed by the Mafiosi is not silence but muteness born of fear. When Peter denied Christ thrice before the cock crew, that was not the right silence. The elders failed to speak and were silent, when the Pandava queen was disrobed; that was a silence of adharma.

Being quiet is a kindness to others and to us. It is an act of respect. It is an act of ahimsa. Actually it is the incessant noise that translates into violence in our lives. As a city we must stop being noisy. Is Chennai afraid of silence? We fill our space with noise, or at least with texting, shuffling or ipoding, which are all noise too of a different kind.

As I said, our marriages are noisy, our last processions are noisy, our religious celebrations are noisy, we are buffeted by noises and have got so used to it that we have become strangers to that silence which is the stillness of being.

I see walkers wiring their ears with some music. Actually there are birds even now in Chennai. Please listen to those minstrels. That music may soon die into eternity. But no, we proudly walk with wired ears not wanting to listen to the ‘cheep cheep’. Is it so difficult to be with myself in silence, that even when I walk I need aural company? Zen master Thich Nhat Hanh recommends walking meditation where the very simple act of walking is transcended into a deeply healing tool which tells us how to be in the here and now.

The Dakshinamurthi icon creates for us a teacher and students learning in silence. There is a verse which is a beautiful study in contrast and it is also about silence. It asks us to picture at the base of the vata tree the aged disciples and the young teacher! The teacher explains wordlessly and the doubts of the students are shattered. The scene is so tranquil and so peaceful. He is not burdened by the thought of having to teach the hardest lesson, the Lesson of Knowledge. The space under the shade of the tree is one of silent communication and silent communion. Knowledge is transmitted easily and in silence because the students are ready to receive it. Their minds are silent too, not clamouring with conflicting thoughts. The space is free of noise; both noise inside and noise outside.

But what about today’s teacher? We will look at the ordinary teacher who is buffeted by myriad problems, who is there only for the paycheck and not for love of teaching or for love of children. There is neither peace nor tranquillity in her mind nor in her life. Her students do not know what silence is, for they come from noisy homes and are sent to noisy schools. She scrawls her name in the staff register, and rushes into the classroom, unprepared for that day’s lesson. The first words she says are, “Children! Silence please!” The children may stop shouting, but that is not the learning silence. We must teach children the richness of silence. We must teach them the virtue of being quiet. We must teach them not to be restless in silence.

Every religious tradition has the vow of silence or practice of silence as an integral part of it. The technique of Vipassana is about learning to be silent. The Cistercian Order or Trappist Order is very strict about silence. Obviously, then, silence is a sine qua non for spiritual evolution. The largest Muslim country in the world, Indonesia, declares a national holiday each year to mark the Hindu-majority Bali’s day of silence, Hari Raya Nyepi Tahun Baru. This profound concept has been absorbed into the beautiful Muslim-Hindu culture of that unique nation. It seems that on that day the streets are empty, no TV, no radio, no entertainment, nothing. It is a day devoted to introspection. Though it is a Hindu festival, everyone, even non-Hindus, willingly adopts silence that day. Imagine the whole of India turning inwards and silent for a day! Do you think we can start with Chennai? Nope. I have as much hope as an icicle has of survival in hell.

There is a book called, The Sacred Tree, compiled by The Four World Development Project from contributions by the Native elders, spiritual leaders and professionals of various Native communities in North America. It is a stunning evidence of the wisdom of the original people of North America. How much have we lost by not listening to such people? In this book, we read, “A sign that much work is needed in the area of personal spiritual growth is when a person dislikes being alone, and especially dislikes being alone in silence. Many people use television or recorded music to fill the silence so that they do not have to experience themselves as they really are. To face ourselves in silence, and to love ourselves because the Creator has made us beautiful are things that every developing human being needs to learn.” Wow! All of us, not just the Chennoise are stunted in spiritual growth, tested against this standard. Sigh!

Tampering with autorickshaws' silencers leads to noise pollution

Tampering with autorickshaws' silencers leads to noise pollution

Autorickshaw drivers say MTC buses and other vehicles do not adhere to norms either



CHENNAI: Fifty-year-old K.E. Rajamannar, a resident of Velachery, has a curious wake-up alarm. It is the deafening sound from an autorickshaw zipping past his home. The noise wakes him with a start at 5.30 a.m. with alarming regularity.

Marginal savings

Most of the 53,000-odd autorickshaws in the city operate with tampered silencers.

Autorickshaw drivers admit that it is a violation of noise pollution norms, but cite marginal savings on fuel and better pick-up acceleration as factors that push them to tamper with the silencer.

The noise is extremely irritating. We are losing peace. I am not an expert, but something should be added or removed from the silencer to convert the vehicles into normal autorickshaws,” says Mr. Rajamannar.

Autorickshaws coming out of the production line have something called ‘noise mufflers'. The cup-shaped device encloses the silencer and helps in reducing the noise from the exhaust.

However, autorickshaw drivers such as J. Seshasayanam, general secretary of the Madras Metro Auto Drivers' Association, say that the first thing that a driver does to a new vehicle is to remove these mufflers.

“The cups restrict the smooth flow of exhaust air. By removing it, drivers achieve better pick-up acceleration and also marginally save on fuel cost. It is also a business tactic. The public has to hear the sound of an autorickshaw approaching,” he says.

Though he accepts that it is mistake, Mr. Seshasayanam says that even MTC buses and other government vehicles do not adhere to noise pollution norms and “we cannot be expected to be perfect”.

Never checked

He adds that it is easy to get through the Fitness Certificate (FC) process despite the silencer tampering as “most vehicles are never checked.”

Though complaints from residents and road users about the sound emanating from the autorickshaws is increasingly becoming common, only 119 cases were registered against the drivers for silencer tampering in 2010.

C. Jacinth, Director, Institute of Otorhino Laryngology, Government General Hospital, says that while the human ear can tolerate noise levels of only 70dB, engine noise from autorickshaws with tampered silencers can go up to 140 dB.

In a recent study done by the hospital on hearing impairment among street vendors, most participants showed signs of partial deafness.

“Noise pollution is a serious menace. But nobody is addressing it,” said Dr . Jacinth.

Sumaira Abdulali of the Awaaz Foundation, an NGO that works in the field of noise pollution, says that autorickshaw drivers have simply not been told that noise is harmful and illegal.

Dangerous trend

“Similar to the mandatory Pollution Under Control (PUC) certificate, vehicles must be made to undergo regular noise checks and certified. Noise is as much an aspect of a vehicle's road worthiness as anything else. To be heard above the noise that their engines generate, motorists are resorting to louder horns. This is a dangerous trend,” she adds.

M. Ravi, Additional Commissioner of Police (Traffic), said that autorickshaw drivers cannot claim fuel saving as an excuse to violate the law.

“If it is not permitted, it is illegal. We will have to go in for random checks in coordination with the Transport Department to curb this practice.”
