# How loud is a dehumidifier?

A refrigerated coil that condenses water out of room air into a tank or a drain hose.

> Manufacturer-declared levels for household compressor units.

## How that compares

*Dehumidifier against things of a similar loudness.*

- Air compressor: 60–92 dB

- Washing machine: 70 dB

- Dehumidifier: 42–58 dB
- Dishwasher: 38–62 dB
- Air purifier: 24–60 dB

## How long you can safely listen

No exposure limit — this is below the level that damages hearing.

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.
