threshold of pain

In hearing, the Threshold of pain is the sound pressure or sound pressure level beyond which sound becomes unbearable for a human listener. This threshold varies only slightly with frequency. Different values for the threshold of pain are found in the literature:

sound pressure level	sound pressure
120 dBSPL	20 Pa
130 dBSPL	63 Pa
134 dBSPL	100 Pa
137.5 dBSPL	150 Pa
140 dBSPL	200 Pa

The volume in acoustics refers to loudness. It is a common term for the amplitude of sound, the sound pressure or the sound pressure level (SPL). Hearing loss due to loud sound is preventable. The best way to prevent exposure is not to be exposed. Turn your stereo down and stay away from night clubs. Try to live far away from construction areas. Keeping away from loud noises is the best way to prevent hearing loss.
