Hearing loss occurs due to many reasons. Out of the many causes and types of loss in hearing, Noise-Induced Hearing Loss (NIHL) is a major one. We have from time to time through many of our earlier blogs, like the one titled “Beware: Recreation noise may put you vulnerable to Noise Induced Hearing Loss” tried to make you aware of the dangers of Noise Induced Hearing Loss. Apart from Recreational Noise, Noise pollution is also induced hearing loss. It is because of this menace the Government of India is also seeking steps to curb noise pollution in the country. We will through this blog try to make you aware of Noise Induced Hearing loss and also how the Government is planning to curb noise pollution.
Noise-Induced Hearing Loss (NIHL): What it is and the dangers it poses
Sounds can be harmful if they are too loud, even if they last for a brief time. But they can particularly cause damage to our hearing if they are both loud and are long lasting. They can damage our sensitive inner ear and cause Noise-Induced Hearing Loss. This damage can occur to anyone irrespective of any age. This type of loss of hearing can be immediate and may sometimes go unnoticed. It could be temporary or permanent. It could affect a single ear or both. We have already made you aware of how you could try and prevent it by turning down on the volume of recreational music and other steps. The Government too has realise the importance of the need of cutting down on noise pollution and thus working on steps to cut down on the same.
The steps the Government is planning
The ministry of road transport and highways is considering a proposal to reduce the maximum permissible decibel range of vehicle horns. This is the main move aimed at curbing noise pollution from compulsive honking on Indian roads. At present according to the Central Motor Vehicle Rules, 1989, the noise range for horns has been fixed between 93 decibel (dB) and 112dB. The decibel is measured at a distance of 7.5 meters from the horn and at a height of 0.5 to 1.5 meters. The ministry is planning to cap this maximum range to below 100 dB. Before going in for the finalization in this regard the Government is already discussing the matter with automobile manufacturers and also with the Society of Indian Automobile Manufacturers. Experts in the field are warning that chronic exposure to sound beyond 93dB for eight hours can cause irreversible hearing loss. Horns are a major contributor to noise pollution in Indian cities.
In most of the European countries the noise limit for vehicle horns is 87 dB while the upper limit is 112 dB. In case of Canada and Australia the upper limit is fixed at 100 dB. If the steps in this regard are finally implemented by the Government it would indeed be a big step forward towards prevention of hearing loss.
Hearing loss brings about various physical and mental problems. Thus with more steps being taken towards the prevention of hearing loss we would indeed be a healthier nation.
