What is the maximum distance at which the riveter is still audible?
The intensity of a sound produced by a point source decreases as the square of the distance from the source. Consider a riveter as a point source of sound and assume that the intensities listed in Table 12.1 are measured at a distance 1 m away from the source. What is the maximum distance at which the riveter is still audible? (Neglect losses due to energy absorption in the air.)
By how many times must the distance from a point source be increased to reduce the sound intensity by half?
Increase the distance by 70.7% . To 1.707 times the original distance.
The pitch of a sound is the distance from the sound source?
The pitch of a sound means the frequency. That stays constant with distance. You mean the sound pressure level that decreases with distance.
What distance is loudness of sound measured?
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
Can volcanic eruptions be as loud as a bomb?
The sound of the eruption of Krakatoa travelled for thousands of miles. Far, far louder than any bomb. Never forget to tell the distance of the measuring point from the sound source, because the closer you are to the eyplosion of the bomb or the eruption of the volcano the louder it will be. 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.
Decibels in ear?
Never forget to tell the distance of the measuring microphone (at the place of your ear), from the the sound source because the closer you are to the sound source the louder it will be.The sound pressure level decreases by 6 decibels 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.
Why does the pitch of a sound change as the source of the sound that moves past you?
Decreasing velocity, and distance.
How loud is 10W?
The effect of the sound pressure on your ears depends on the distance to the sound source.
True or false your distance from a sound source affects how loud the sound seems?
true
How loud is a jet?
A jet at 100 m distance can have a sound pressure level of L = 140 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.
How loud is a Boeing 747?
A Boeing 747 at 100 m distance can have a sound pressure level of L = 130 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.
On what factor the loudness of sound depend upon?
The loudness of a sound depends on the amount of energy it takes to make the sound and the distance from the source of the sound.
