Does your distance from a sound source affect how loud the sound seems?

The sound pressure decreases with distance r in a free field (direct field). The next question is. How does the sound decrease with increasing distance? After which law? Answer: The sound pressure p diminishes with distance after the 1/r law. Sound pressure decreases inversely as the distance increases with 1/r from the sound source. The Sound pressure level (SPL) decreases by (−)6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value. Sometimes it is said, that the sound decreases with with 1/r², the inverse square law. That is really wrong. Scroll down to related links and look at "Damping of sound level with distance".

Does sound get quieter or louder through medium?
Sound does indeed get quieter through medium. The level of loss depends on the medium that is used, and as the square of the distance from source.
Is a sound wave continuous?
A sound wave is continuous for as long as the sound vibrations are being made at its source.
How loud a sound seems is determined by what measurement of the sound waves?
Loudness is determined by the amplitude of the sound waves.
The source of every sound is something that is?
Vibrating
How quickly a sound reaches your ear depends on?
It depends on the distance it has to travel.
True or false your distance from a sound source affects how loud the sound seems?
true
Why does moving away from a radio affect the loudness you hear?
because sound waves spread out, intensity decreases with distance from the source.
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.
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
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.
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.
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.)
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.
