How loud is jet engine dB?
In fact, at 140 decibels (a unit to measure the intensity of sound), the noise of a jet plane is only 40 decibels away from damaging our hearing tissues and 54 decibels away from the loudest noise possible. Compared to other moderate or loud dB levels (of up to 85 decibels), 100 decibels is considered very loud and dangerous to human hearing. When measuring a sound, a 10 dB increase equals a 10-time increase in the intensity of the sound.B is as loud as a quiet conversation, a quiet suburb, a quiet office, or a quiet refrigerator. Notice the use of the word ‘quiet’ when describing this noise level?
