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?
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.

p2 / p1 = r1 / r2 and p2 = p1 x r1 / r2
p1 = sound pressure 1 at reference distance r1 from the sound source.
p2 = sound pressure 2 at another distance r2 from the sound source.

The relationship between sound intensity and distance is that sound intensity decreases as distance from the sound source increases. This is because sound waves spread out as they travel, causing the intensity of the sound to decrease with distance.
The amplitude of sound is influenced by the intensity or energy of the sound waves, which determines the loudness that we perceive. It is also affected by factors such as distance from the sound source, the medium through which the sound travels, and any obstacles or barriers in the path of the sound waves.
The pitch of a sound means the frequency. That stays constant with distance. You mean the sound pressure level that decreases with distance.
The sound distance formula, also known as the speed of sound formula, is used to calculate the distance traveled by sound waves in a given medium. It is represented as distance speed of sound x time.
the Doppler effect, which causes the observed frequency of a sound wave to decrease as the source moves farther away from the observer. As the sound waves spread out over a larger distance, the observer perceives a lower pitch.
The effect of the sound pressure on your ears depends on the distance to the sound source.
The sound pressure decreases with distance after the distance law 1/r. (No squre!) Our ear drums are only moved by the sound pressure of the air. Scroll down to related links and look at "Inverse Distance law".
For example when firemen car passes around them. The sound is distorted according to distance in which the car is.

it does effect the distance because it is far
to measure sound from distance use decibels
the Doppler effect, which causes the observed frequency of a sound wave to decrease as the source moves farther away from the observer. As the sound waves spread out over a larger distance, the observer perceives a lower pitch.
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
The iconic sound effect heard in Star Wars movies that is often described as a "laser sound" is the blaster sound effect.
