This is a typical wrong believe that a jackhammer has 110 dB, a rock band has 120 dB and a jet engine must have 130 dB. Every one seems to be content with these wrong numbers.
If there is no given distance with the measured decibel value, such numbers are really nonsense.
With doubling the distance from a sound source the decibels decrease by 6 dB.
So a jet engine sound can be at 12.5 m distance 130 dB. At 25 m distance 124 dB, at 50 m distance 118 dB and at 100 m distance only 114 dB.
You see how important it is to tell always the distance with the measured decibel level. Don't believe that only a specific decibel value belongs to noise source.
120 decibels is the sound of a jet engine, or the volume of loud rock music at a concert.
a jet plane at a takeoff at 100 yards is 120 dB loud
A jet enjine at take-off measures 113 decibels, while a surprised pig can squeal at 115 decibels.
Sound is measured in decibels. Decibels are units used to measure the intensity of sound. The highest decibel alarm clock available is 120 decibels, which can be compared to be as loud as the sound of a fire engine siren.
The scream of a jet engine taking of measures 113 decibels. the scream of a frightened pig can measure 115 decibels.
Aome machines claim to spin at 74 decibels. Is that loud?
Fundamentally, 43 decibels is loud. It is probably enough to annoy neighbors, but anything 85 decibels is enough to hurt hearing.
that year had the jet engine option
About as loud as a normal conversation.
100 times as loud as breathing
KISS concerts a measured at an ear splitting 130-150 decibels depending on your seat in the arena. Higher than that of the controversial Concord jet.
