Listen to a cicada chorus
How loud is a cicada chorus?
A cicada chorus is about 100 dB, with a typical range of 90–120 dB. Some species exceed 100 dB at 50 cm.
That is about 16 times as loud to the ear as normal conversation and 1e+04 times the sound energy.
Can it damage your hearing?
Yes, with enough exposure. At 100 dBA, NIOSH recommends a daily limit of 15 minutes; at the top of the range (120 dB) it is 9 seconds. 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.

Safe listening time
| Level | NIOSH recommended limit | OSHA legal limit (US) |
|---|---|---|
| 94 dBA | 1.0 hours | 4.6 hours |
| 97 dBA | 30 minutes | 3.0 hours |
| 100 dBA | 15 minutes | 2.0 hours |

| 106 dBA | 3.8 minutes | 52 minutes |
NIOSH: 85 dBA for 8 hours with a 3 dB exchange rate; OSHA: 90 dBA for 8 hours with a 5 dB exchange rate. General information, not medical advice – see a hearing professional about ringing ears, muffled hearing or pain.

Frequently asked questions
How many decibels is a cicada chorus?
About 100 dB, with a typical range of 90–120 dB.
Is a cicada chorus louder than a jet engine?
No – a jet engine at takeoff is about 140 dB at 30 m, while a cicada chorus is about 100 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.
