How loud is a air compressor?

Typical loudness
60–92 dB

A pump that stores compressed air in a tank to drive nailers, wrenches and spray equipment.

Manufacturer declarations; oil-lubricated and rotary-screw units are much quieter than oil-free direct-drive ones.

How that compares

Air compressor against things of a similar loudness.

Hair dryer 75–95 dB
Pressure washer 75–95 dB
Lawn mower 80–85 dB
Leaf blower 65–92 dB
Air compressor 60–92 dB
Vacuum cleaner 62–85 dB
Washing machine 70 dB

How long you can safely listen

Safe for a full day, though prolonged exposure is tiring.

Decibels are logarithmic, which makes the intuitive arithmetic wrong in a way worth knowing: every 10 dB is ten times the sound energy, and two identical sources together are 3 dB louder than one — not double. So two 70 dB fans are 73 dB, not 140 dB.

Levels are measured at roughly one metre unless stated otherwise. Sound falls off with distance — about 6 dB per doubling — so the same appliance is noticeably quieter across a room than beside your ear.
