In the range of safe sound levels (let’s say up to 85 dBA for a 8 hour exposure) adjustment should not be restricted. When you notice a difference between loud sounds and quiet ones, your ears are perceiving changes in sound pressure level. Normal conversation is around 40dB to 60dB, a whisper around 30dB. Many hearing professionals believe that these permissible levels are still too high for hearing safety.

You have a greater chance of getting noise-induced hearing loss if you are in an environment with these noises for any extended time period. Normally, we hear these sounds at safe levels that do not affect our hearing. Noise-induced hearing loss typically occurs at high sound levels. Occupational safe noise levels are set at around 85 dB SPL (Nat.

What people don’t realise is that any loud sound can damage hearing.’. ‘It’s hard to quantify a safe set level because the output of every player is different,’ says Robert Beiny. A normal conversation is around 65 decibels (db); under 75db your ears are safe. A blast of noise over 110db for two minutes can hurt your ears immediately. Loud noises blast and irreversibly damage these cells, leading to hearing loss and sometimes tinnitus, an unpleasant condition in which you hear ringing, whooshing or high-pitched whining sounds. Loud sounds damage our ears (either instantly or eventually). That is not open to question. Normal human speech lies in the range of 50 to 60 dB.
