|
| 120 dBSPL | 20 Pa
|
| 130 dBSPL | 63 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.
