noise decibel reference
The noise decibel is mainly divided into three levels within 0~120DB
|Class 30~59dB)
Tolerable, but already uncomfortable, when it reaches 40dB, it begins to disturb sleep
Class II (60~89dB)
Increased interference to the nervous system, difficulty in obedience, 85dB is generally required to protect hearing
Class III (90~120dB)
Significantly damages the nervous system, causing irreversible damage to the hearing organs
