Hearing can be damaged by sound over?

Answer 1

It's the sound pressure deviation we measure as sound pressure level (SPL). The threshold of pain is known in acoustics as the lowest strength of a stimulus that is perceived by the ear as painful. Because of the different sensitivity of the hearing of people it cannot be given an accurate value. You can find the following rounded values for threshold of pain in various audio articles and books:

140 dB SPL equivalent to 200 Pa

137.5 dB SPL equivalent to 150 Pa

134 dB SPL equivalent to 100 Pa

130 dBSPL equivalent to 63 Pa

120 dBSPL equivalent to 20 Pa

Sound pressure levels more than 140 dB at your ears will burst your eardrums.

Don't forget that the distance from your ears to the sound source is very important. So keep off.
