1. NIHL (Noise Induced Hearing Loss
) may occur at the following rate:
at 120dB+ (next to rock speakers) immediately.
at 100 dB (loud music) after only 15-30 min of use.
at 85 dB over 8 - 10 hours of use.
at 70 dB (soft music) there is no risk.
2. NIHL usually starts with a temporary threshold shift (TTS) where your ear feels blocked, sometimes with Tinnitus
(hissing noise in ear) . If you can avoid further exposure to loud music. your ears will recover and no permanent loss will occur.
3. There are no medicines to protect your ears from hearing loss. NIHL may also be insidious in onset, which means that initially you yourself may not realize that you are developing hearing loss.
4. The best way to check is to get a PTA (Pure Tone Audiogram) done. Lower the volume or use Noise Cancelling Headphones.
