How long you can safely listen

About 4 hours a day before hearing protection is recommended.

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.
