Listen: sounds near 80 dB
How loud is 80 dB?
80 decibels is loud. 80 dB sounds about 4.0 times as loud as normal conversation (60 dB), and it carries 100 times the sound energy. Typical sounds around this level: busy restaurant, toilet flush, vacuum cleaner.
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 80 dB safe?
For most people, short exposure to 80 dB is not harmful. The US EPA identified 70 dBA averaged over 24 hours as a level that protects against hearing loss over a lifetime, so long, all-day exposure is worth reducing.
