Answer
NOISE POLLUTION.
Noise pollution is unwanted or excessive SOUND that disturbs living organisms.
It differs from the other kinds of pollution in one important way, worth noting: it leaves NO RESIDUE. Air, water and soil pollution involve a SUBSTANCE that remains in the environment; noise is ENERGY and ceases the moment the source stops. That makes it easier to control but no less harmful while it lasts.
THE SAFE LIMIT is about 80 decibels for continuous exposure.
