How loud is 17 dB?

17 decibels is very quiet. 17 dB sounds about 19.7 times quieter than normal conversation (60 dB), and it carries 5.01e-05 times the sound energy. Typical sounds around this level: normal breathing, rustling leaves, ticking watch.

Decibels are logarithmic: every +10 dB means ten times more sound intensity but is heard as only about twice as loud, and every +6 dB doubles the sound pressure. That is why a few decibels can make a big difference.

Is 17 dB safe?

Yes. 17 dB is far below the levels that damage hearing. In bedrooms, the WHO recommends night-time levels around 30 dB or lower for undisturbed sleep.
