Loud sounds and hearing loss

img_3051The Ganesh festival comes along and brings with it high decibel sounds. It’s not just the loudspeakers but also the dhol tashas which are ruining our health. Wedding or festival, India is rushing towards a hearing epidemic.

Calling out to world-class companies which manufacture hearing aids. Please set up shop in India because we will need you soon.

And if anyone reading this is studying to be a doctor, best get for an ENT specialisation. You will make money.

It doesn’t matter what the laws say, what the courts say – this sound pollution is continuing. Ban loudspeakers and the people turn to dhol tashas. Any objection to loud sounds is considered against religion. It has now become a religious duty to ruin people’s health and well-being. As long as the noise-makers “enjoy”. Their enjoyment will not last and will end earlier than they wish. In old age they might not even be able to enjoy television or sit on benches, chatting with their friends. Hearing aids can only enhance hearing which is already present. Once hearing goes, hearing aids do not work.

The reason for irresponsible noise pollution is just one: Ignorance.

These are the after-effects of even moderately loud sounds:

  1. Lessens efficiency
  2. Increases hostile and anti-social behaviour
  3. Decreases learning
  4. Increases chances of accidents
  5. Harms the unborn baby
  6. Causes gradual hearing loss.

After effects of sounds above 100 decibels:
Take all of the above and enhance it. And of course, the chances of hearing loss goes up exponentially.

This is a scientific explanation as to why loud sounds cause hearing loss. It may not destroy your ears or burst your ear drum at one go, but you will suffer.

  1. Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum.
  2. Then the eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
  3. The bones in the middle ear send the sound vibrations to the cochlea of the inner ear, which is shaped like a snail and filled with fluid. There is an elastic partition from the beginning to the end of the cochlea.
  4. This partition is a membrane on which key hearing structures sit.
  5. The vibrations cause the fluid inside the cochlea to ripple, and a wave forms along the membrane. This causes the hair cells—essential sensory cells sitting on top of the membrane—to move.
  6. There are microscopic hair-like projections on top of the hair cells.
  7. These hair cells are damaged over time, due to exposure to loud sounds.
  8. This leads to hearing loss.

India will soon face an epidemic of hearing loss as the people who are exposed to loud sounds grow older.
