How loud is a busy restaurant?
A busy restaurant is about 75 dB, with a typical range of 70–85 dB. Hard surfaces and many voices push levels up.
That is about 3 times as loud to the ear as normal conversation and 31.6 times the sound energy.
Can it damage your hearing?
Yes, with enough exposure. At 75 dBA, NIOSH recommends a daily limit of 80.6 hours; at the top of the range (85 dB) it is 8.0 hours. Wear earplugs or earmuffs, keep your distance and limit time near the source.
How sound level changes with distance
Decibel figures always depend on distance. For a small source in open air, every doubling of distance lowers the level by about 6 dB; indoors, reflections reduce that drop. Use the sound-vs-distance calculator to estimate the level where you are.

Frequently asked questions
How many decibels is a busy restaurant?
About 75 dB, with a typical range of 70–85 dB.
Is a busy restaurant louder than a jet engine?
No – a jet engine at takeoff is about 140 dB at 30 m, while a busy restaurant is about 75 dB.
How are these levels measured?
With a sound level meter, usually A-weighted (dBA) to match human hearing. Published figures depend on distance and conditions, so treat them as typical values.
