Sound meter work efficiently to find the level of environmental noise including acoustic. Sound detector is known as meter or decibel meter (db meter). Through Sound detector or noise detector you can easily detect too much loud or too much low sound in order to prevent your hearing functionality.

Sound Meter - Decibel Meter, Noise Meter Key Features:
-Display the current noise reference
-Display min/avg/max decibel values
-Display decibel by graph

Sound Level:
- 0dB is the weakest sound that a person can just hear
- 30dB～40dB is an ideal quiet environment
- More than 50dB will affect rest and sleep
- More than 70dB will affect study and work
- More than 90dB will affect the hearing
- If suddenly up to 150db, the tympanic membrane will rupture and bleed, and lose hearing completely

Levels of Noise In decibels (dB) according to the American Academy of audiology, from 20 dB to 120 dB between the division. The high decibel value will be harmful to your physical and mental health and hearing function. You'd better avoid exposure in noisy environments.
