Listen: sounds near 118 dB
How loud is 118 dB?
118 decibels is extremely loud. 118 dB sounds about 55.7 times as loud as normal conversation (60 dB), and it carries 6.31e+05 times the sound energy. Typical sounds around this level: baby crying, bagpipes, lion roar.
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 118 dB dangerous?
Yes, with enough exposure. NIOSH recommends no more than 14 seconds per day at 118 dBA (US law, via OSHA, allows 9.9 minutes). Hearing damage from noise is cumulative and permanent, so use earplugs or earmuffs, increase distance or reduce exposure time.
