How loud is a movie theater?
A movie theater is about 85 dB, with a typical range of 74–104 dB. CDC gives 74–104 dB depending on the film and seat.
That is about 6 times as loud to the ear as normal conversation and 316 times the sound energy.
Can it damage your hearing?
Yes, with enough exposure. At 85 dBA, NIOSH recommends a daily limit of 8.0 hours; at the top of the range (104 dB) it is 6.0 minutes. 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 movie theater?
About 85 dB, with a typical range of 74–104 dB.
Is a movie theater louder than a jet engine?
No – a jet engine at takeoff is about 140 dB at 30 m, while a movie theater is about 85 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.
