What happens to the energy of a sound wave as the source gets farther away?
As a sound wave travels away from the source, its energy spreads out over a larger area, leading to a decrease in the intensity of the sound. This reduction in energy leads to a decrease in the loudness of the sound as it travels farther away.
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.
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.
What is the relationship between sound distance and the perception of volume in a given environment?
The relationship between sound distance and the perception of volume in a given environment is that as sound travels further away from the source, it tends to decrease in volume. This is due to the dispersion of sound waves over distance, resulting in a decrease in intensity and perceived loudness.
How can the loudness of a sound decrease?
Loudness is a person's perception of the intensity of a sound wave. A sound wave can be generated by any object able to impart energy to the environment, such as a set of speakers, clapping hands or a laser pulse through the air. Decreasing loudness can be done by removing energy from the sound wave. Generally this is done by adding a dampening material (like foam) in between you and the source of the sound. However, one can also remove the medium over which sound travels (i.e. remove the air and create a vacuum). An extremely loud and powerful sound source on earth would be inaudible on the moon
Why does the loudness of a sound wave decrease as the wave travels away from it source?
The energy in the sound's vibration dies down, until it is no longer audible.

As a sound wave travels away from the source, its energy spreads out over a larger area, leading to a decrease in the intensity of the sound. This reduction in energy leads to a decrease in the loudness of the sound as it travels farther away.

Which is a similarity between loudness and pitch?
There is no similarity. Loudness has to do with sound pressure amplitude coming from the sound source. Pitch has to do with the frequency of the tone the sound source is making. Loudness cannot be pitch.

What will happen to the loudness if The distance between the source and the observer is doubled?
If the distance between the source and the observer is doubled, the loudness of the sound will decrease by about 6 decibels. This is because sound intensity decreases with the square of the distance from the source due to the spreading out of energy over a larger area as the distance increases.
What two factors dos loudness depend on?
The loudness of a sound depends on the amplitude of the sound waves, which is related to the intensity or power of the sound source. It also depends on the distance between the sound source and the listener, as sound waves lose intensity as they travel through space.
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.
On what factor the loudness of sound depend upon?
The loudness of a sound depends on the amplitude of the sound wave. A higher amplitude corresponds to a louder sound. The human perception of loudness also depends on the frequency of the sound wave and the sensitivity of the human ear.
What is the relationship between the distance from the source and loudness?
The relationship between distance from the source and loudness is that as distance increases, the sound intensity decreases, resulting in lower perceived loudness. This follows the inverse square law, meaning that the sound intensity is inversely proportional to the square of the distance from the source.
