130 Decibels — How Loud Is It?

Dangerous

130 dB is about as loud as jet engine at takeoff, 30 m away. A jet engine at takeoff, 30 meters away, reaches about 130 dB — commonly cited as the threshold of pain, where sound pressure becomes physically uncomfortable rather than merely loud. Brief exposure at this level can cause immediate, permanent hearing damage.

What does 130 dB sound like?

  • 130 dB — Jet engine at takeoff, 30 m away
  • 130 dB — Threshold of pain
  • 125 dB — Balloon popping

Safe exposure time at 130 dB

Under NIOSH's Recommended Exposure Limit (85 dB, 3 dB exchange rate), safe unprotected exposure at 130 dB is about 1 second per day. Under OSHA's legal Permissible Exposure Limit (90 dB, 5 dB exchange rate), it is about 2 minutes per day.
