Exposure to 140 dB of sound should be minimized as much as possible as it can cause immediate hearing damage or loss. Prolonged exposure to this level of sound can result in permanent hearing damage. Protective equipment like earplugs or earmuffs should be worn in environments where 140 dB of sound is present.
Sound strength is measured in decibels (dB), with a normal conversation around 60 dB, a rock concert around 120 dB, and a jet engine around 140 dB. Prolonged exposure to sounds over 85 dB can damage hearing.
The sound pressure or its level can be harmful if it is moving too much your eardrums. "Permitted Exposure Time Guidelines - SPL" Sound pressure level Lp and permissible exposure time t: 115 dB = 0.46875 minutes (~30 sec) 112 dB = 0.9375 minutes (~1 min) 109 dB = 1.875 minutes (< 2 min) 106 dB = 3.75 minutes (< 4 min) 103 dB = 7.5 minutes 100 dB = 15 minutes 97 dB = 30 minutes 94 dB = 1 hour 91 dB = 2 hours 88 dB = 4 hours 85 dB = 8 hours 82 dB = 16 hours Lower dBs are said to be harmless.
94 dB is considered to be loud and can cause hearing damage with prolonged exposure. It is similar to the noise level of a motorcycle or a lawnmower at close range.
The acceptable noise level in a residential area is typically around 55 decibels (dB) during the day and 45 dB at night. A 55 dB noise level can impact the quality of life for residents by causing annoyance, sleep disturbances, and potential health issues over time.
100 dB is considered very loud and can cause hearing damage with extended exposure. It is approximately as loud as a chainsaw, a jackhammer, or a rock concert. It is recommended to use ear protection in environments with noise levels reaching 100 dB.
90 dB(A) is the OSHA 8 hour TWA 115 dB(A) is the OSHA 15 min Short Term Exposure Limit 140 dB(A) is the OSHA ceiling Exposure above these levels can cause hearing damage.
Sound strength is measured in decibels (dB), with a normal conversation around 60 dB, a rock concert around 120 dB, and a jet engine around 140 dB. Prolonged exposure to sounds over 85 dB can damage hearing.

A normal conversation is about 70 decibels (dB). A gun firing off is about 140 dB.
On takeoff, anywhere from 140 - 150 dB.
Depending on the aircraft and type of engine, it will be around 140 DB.

Depending on model, a mounted LRAD is rated between 140 and 160 dB at the source, with a loss of 6 dB each time distance from the transmitter is doubled.
Any gunshot above 140 dB will damage your hearing. An M16 is 155-163 dB An M60 is 155 dB at the shooters position.
