0 decibel was originally defined as the average threshold of hearing of a person.[with the usual proviso that they were not a boilermaker, had congenital deafness ... ... .]Thus one half of the population will have hearing more sensitive than this, and one half less sensitive. Ordinary speech is around the 55dB to 70dB.Sounds greater than 85dB are considered to be damaging, if over an 8 hour period.That is the sounds against which you'd have to raise your voice significantly to be heard at 600mm distance. At this level and above, you should be wearing hearing protection.At levels above120dB you will start to feel pain. At levels above 130dB there will be instant damage.[A fighter pilot's helmet is designed to shield as much of the hard tissue of the head from sound as possible, in order to prevent hearing loss. ]
