Stops a single dropped book setting it off.
Only useful if you have a real meter to match.
This is not a sound level meter. The number is a relative level from 0 to 100, useful for comparing "now" against "a minute ago" in one room with one device. It is not decibels and cannot be: a browser gives no access to the microphone's absolute sensitivity, and the operating system may be applying automatic gain that changes as the room changes. For anything involving hearing safety or a noise complaint you need a calibrated meter, not a laptop.
