RS PRO LCD sound level meter
Question about RS PRO LCD sound level meter
At what maximum distance can it detect sounds?
What are you gonna use it for?
Essencially it measures air pressure created by a sound wave at the point of the device, the sound pressure will depend on the loudness of the source and the distance to the source. Each doubling of the distance reduces loudness by 6dB. The minimal level the device detects is 35dB, it is approximately whispering nearby.
