Listening to a sound above 85 dBps (decibels per second), can be harmful for one's ears. At an average, people (especially youngsters) listen to music or other sounds around or above 100 dBps, which damages the ear to a certain extent. A human ear is exposed to thousands of sounds daily, but those sounds don't damage ears. Listening music at a loud sound with headphones on for a long time can cause damage to ears.

30 years ago, people in their 20s could all hear to the low pitched sounds easily, like rustling of leaves, drip of rain drops. But now, for 1 in 5 of them, those sounds are gone forever. Doctors say, normally people aged 50 -60 years, used to consult them for hearing related problems, but now, people who are 40 or below are consulting them for the same because of their regular exposure to high volumes and increasing proneness towards hearing damage or loss.

Below are some loudness and time facts, you should think about before listening to a headphone.

-Hearing at 95dB,may damage the hearing and cause pain within four hours of exposure.

-Hearing at 100dB,may damage the hearing and cause pain within two hours of exposure

-Hearing at 105dB,may damage the hearing and cause pain within one hour of exposure

With the increase in every 5dB ,the damage can occur within the half of the time of the last exposure. But, after 120dB, the damage may occur immediately to the ears, causing a hearing loss.

Hearing damage or loss can happen in two ways:

1. Temporary Threshold Shift- Its a situation in which hearing ability of a person is either reduced or lost for a while but it is recovered automatically after few hours, with or without medication.

2. Permanent Threshold Shift- Its a phase when a person completely loses his ability to listen. It happens when he is exposed to a high pitched sound on regular basis.

What actually happens inside your ear?

When strong sound vibrations reach your ear, the problem deep inside the cochlea is the fragile hair, they turn vibrations into sound messages and send them to the brain. But the loud sound damages the hair cells and cochlea can't relay the sound messages to the brain.Unlike the damage to other parts of the body, the inner ear/cochlea damage never heals. The more hair gets damage, the more hearing ability gets worse.
