The sound of a jet engine vibrates more than the sound of a lawn mower.
from a distance away why does a jet sound loader than a lawn mower

No
That depends how close you measure to the yach engine. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
Excessive noise is a violation in most states
Amplitude = "Loudness" In that a direct increase in amplitude will cause the sound to be "louder".
The decibels depends how close you measure to the harp. The closer - the louder! And the louder you play the more decibels you get. The distance is very important if you measure with a sound pressure level meter.
Make what sound louder? Your engine? Fit a different exhaust system. with a bigger bore.
In my opinion, the 5.56 and 7.62x39 are very closwe in noise level, the 7.62 being a bit louder. The .308 is about 25% louder. Distance does not matter.
It depends how close your ears are to the lawnmower.AnswerAccording to the chart at the link provided below an average lawnmower puts out about 107 decibels at a three foot distance.A lawn mower at 3 ft distance can have a sound pressure level of L = 100 dBSPL. Never forget to tell the distance of the measuring microphone from the sound source, because the closer you are the louder it is. The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value. The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
Trucks are louder than cars because of the bigger engine and more space for the sound waves to travel in, and the torque on a truck is considerably bigger with a bigger exhaust to compensate for it, which all results in a louder sound.
It does get louder! It increases the amplitude of the sound wave
