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.
How loud a sound seems is determined by what measurement of the sound waves?
Loudness is determined by the amplitude of the sound waves.
Is a sound wave continuous?
A sound wave is continuous for as long as the sound vibrations are being made at its source.
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.
What two factors affect the loudness of sound?
The two factors that affect the loudness of sound are the amplitude of the sound wave, which determines the intensity of the sound, and the distance from the source to the listener, which influences how much the sound wave has spread out and dissipated.
One sound can appear louder or softer than a second sound with an equal intensity?
The perceived loudness of a sound depends not only on its intensity (amplitude of the sound wave) but also on factors such as frequency, duration, and the sensitivity of the human ear. Additionally, the distance between the source of the sound and the listener can also affect how loud a sound seems.
What causes the intensity of sound vibration amplitude?
The intensity of sound vibration amplitude is primarily influenced by the strength of the sound source and the distance from the source. As sound travels further from the source, the amplitude decreases due to spreading out of the energy. Additionally, the medium through which the sound is traveling can affect its intensity.
True or false your distance from a sound source affects how loud the sound seems?
True. The farther away you are from a sound source, the lower the perceived loudness of the sound. This is because sound waves lose intensity as they travel through air, resulting in a decrease in perceived volume.
Why does moving away from a radio affect the loudness you hear?
because sound waves spread out, intensity decreases with distance from the source.
Why does distance affect sound?
Distance affects sound because as sound waves travel through a medium, they gradually lose energy. The longer the distance the sound has to travel, the more energy is lost, resulting in a decrease in sound intensity. This is why sounds often become softer and less distinct the farther they are from the source.
The pitch of a sound is the distance from the sound source?
That is incorrect. The pitch of a sound is determined by the frequency of the sound wave, which is how quickly the sound wave vibrates. It is not related to the distance from the sound source.
What is most likely to affect the distance sound travels before it can no longer be heard?
The main factors that affect the distance sound travels before it can no longer be heard are the intensity of the sound source, obstacles in the environment that absorb or reflect sound waves, and atmospheric conditions like temperature, humidity, and wind speed.
What factors affect the amount of sound energy?
Factors that affect the amount of sound energy include the amplitude of the sound wave (volume), the frequency of the sound wave (pitch), the distance from the sound source, the medium through which the sound travels, and any obstructions or barriers that may absorb or reflect the sound.
What two things affect loudness?
The speed of sound is slower at higher altitudes because the air temperature is lower. The greater the amplitude, the louder the sound. It is your perception of the energy of a sound. What two factors affect the loudness of a sound
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 are two factors that can affect the clarity of an echo?
The distance between the sound source and the reflecting surface can affect the clarity of an echo. The presence of obstacles or sound-absorbing materials near the reflecting surface can also impact the clarity of an echo.
