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 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.
How is the intensity of a sound related to the distance between the source and the receiver?
The intensity of a sound decreases as the distance between the source and the receiver increases. This is due to the spreading out of sound energy over a larger area as it travels further away, resulting in a decrease in the concentration of energy at the receiver.
What causes sound intensity to decrease?
Sound intensity decreases as it spreads out from its source due to the inverse square law, which means that as distance from the source increases, the same amount of sound energy is spread out over a larger area, leading to lower intensity. Additionally, sound absorption by materials in the environment can also cause a decrease in sound intensity.
Decreasing of Sound Intensity?
Sound intensity decreases as the distance from the source increases due to the spreading of energy over a larger area. This decrease follows the inverse square law, meaning the intensity decreases proportionally to the square of the distance. Factors like obstacles and absorption can also contribute to the attenuation of sound intensity.
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Decreasing the amplitude of the sound waves will decrease the intensity of the sound coming from the TV. Intensity is directly proportional to the square of the amplitude, so reducing the amplitude will result in a corresponding decrease in intensity. This means that the sound will be quieter.

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.

Why does the intensity of a sound decrease as the distance from the source increases?
the waves spread out over a larger areathe waves are absorbed by the medium as they pass through itthe waves are being scattered by irregularities in the medium and don't all proceed forwardetc.
By what factor will the sound of a source change the intensity of the waves if the distance is tripled from the sound source?
The intensity of the sound waves will decrease by a factor of 9 if the distance from the source is tripled. This is because intensity decreases with the square of the distance from the source due to the spreading out of the waves in a three-dimensional space.
What is loudness and distance?
Loudness is the perceived intensity of sound, measured in decibels (dB). Distance affects loudness by causing sound to decrease in intensity the further it travels, as sound waves disperse in all directions. The inverse square law states that the sound pressure level decreases by 6 dB for each doubling of distance from the sound source.
Rise and fall in sound intensity?
An increase in sound intensity is known as a rise or an increase in volume, while a decrease is referred to as a fall or decrease in volume. Sound intensity is measured in decibels (dB), with a higher number indicating a louder sound and a lower number indicating a quieter sound. This rise and fall in sound intensity can affect our perception of sound and its impact on our ears.
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.
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.
