Are you looking for the inverse distance law? How sound pressure decreases with distance? Scroll down to related links and look at "Sound pressure p and the inverse distance law 1/r".
to measure sound from distance use decibels
One way to investigate the speed of sound is to measure the time it takes for a sound wave to travel a known distance, like using a stopwatch to measure the time between the sight of a lightning bolt and the sound of thunder. Another method is to use a resonance tube or other equipment to create sound waves and measure the wavelengths at different frequencies to calculate the speed of sound.
They can use formulas that are based on how sound grows weaker over the distance it travels and how the sound will echo off of walls.
sound navigation
Bats use the time of the sonar sound returning to them to determine distance from things, including insects. As the insect gets closer, the sound returns faster to the bat, allowing it locate the insect.
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.
Use the sinnoh sound.
use the odometer
To estimate the distance to a lightning strike, count the seconds between the flash and the sound of thunder. Divide this number by 5 to get the distance in miles, or divide by 3 to get the distance in kilometers.
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.
If you want to be as accurate as possible you will need to start with the temperature of the air. Once you know the temperature of the air you plug it in to this formula: V = 331 √1 + (T/273) V is the velocity of sound in air at temperature T in degrees Celsius. Now that you know how fast sound will travel through the air at the current temperature, measure the time it takes for the sound to be transmitted and the echo received. Take that number and plug it in to this formula: V = m/s or Velocity = meters/seconds From that we get: Distance = Velocity/time Divide the distance in half and you have your distance from the object which the echo bounced off of.
