What is the relationship between sound intensity and distance?
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.
What causes in the change in the intensity of a sound?
The intensity of a sound is affected by the amplitude of the sound wave, which is how high or low the waves are. A change in the distance from the sound source, the medium through which the sound travels, or any obstructions in the path can also affect the intensity of the sound. Additionally, factors like the size and shape of the space where the sound is heard can impact its intensity.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 3?
The intensity of a sound wave would increase by a factor of 9 (3^2) if the distance from the source is reduced by a factor of 3. This is because intensity is inversely proportional to the square of the distance from the source.
How distance affects the loudness of a sound?
As distance increases, the intensity of sound decreases due to spreading out of the sound waves in all directions. This decrease in intensity leads to a reduction in loudness as the sound travels further from its source. At double the distance, the sound intensity will be one-fourth as strong.
Does sound Intensity decrease linearly with distance?
No, it follows the inverse square law. That is, the intensity is inversely proportional to the square of the distance. I2/I1 = (r1/r2)². Intensity decreases with 1/r² from increased distance, while the sound pressure decreases only with 1/r from increased distance.

How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 4?
- 6 dB is incorrect. It will decrease by 12 dB.
How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX

What distance is the sound intensity level 25dB?
Sound intensity level is measured in decibels (dB) and does not directly correspond to a distance. The sound intensity level only quantifies the power of sound. The distance at which a specific sound intensity level of 25 dB would be heard depends on various factors such as the surroundings, obstacles, and the characteristics of the sound source.
By what factor will the sound of a source change the intensity of the waves if the distance is tripled from the sound source?
For sound intensity (acoustic intensity) we use in the free field (direct field) the inverse square law = 1/r². I1 and r1 belong to the close distance and I2 and r2 belong to the far distance.I2 = I1 * (r1/r2)²I2 = I1 * (1/3)² = I1 / 9Three times farther away gives one ninth the sound intensity of the close sound intensity.
How do you change the intensity of sound?
the intensity of a sound wave is a combination of its rate and density of energy transfer.To change the intensity of sound we have to make the amplitude higher or make it lower.
The sound of a bullfrog attracts a mate How much quieter is the sound if the mate is 4 times further away if the sound follows the inverse square law?
Well, it has to follow the inverse square law, so that as distance increases, the sound intensity drops by the square of the proportionate change in distance. The intensity will be 1/16 at 4 times the distance.
By how many times must the distance from a point source be increased to reduce the sound intensity by half?
The distance must be doubled to reduce the sound intensity by half. This follows the inverse square law, which states that sound intensity decreases in proportion to the square of the distance from the source.
