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
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.
The loudness of a sound wave decreases as it travels away from its source due to the spreading out of energy in all directions. This phenomenon is known as sound attenuation, where sound energy is dissipated through interactions with the surrounding medium. Additionally, absorption, reflection, and scattering of sound waves by air molecules and obstacles in the environment contribute to the decrease in loudness.
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.
Loudness is the property of sound that describes our awareness of the energy of a sound. It is subjective and depends on the amplitude of the sound wave.
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.

The energy in the sound's vibration dies down, until it is no longer audible.
When sound waves are in phase and interfere, their amplitudes add together, resulting in a louder sound. On the other hand, when sound waves are out of phase and interfere, they can cancel each other out, leading to a decrease in loudness or even silence, depending on the degree of cancellation.
If the surface area of the vibrating body is decreased, the loudness of the sound will also decrease. This is because less energy is being transferred to the surrounding air, resulting in a quieter sound.

The amplitude determines the loudness of a sound wave.
The amplitude of sound waves is what humans perceive as loudness.
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.
The loudness of sound is determined by the amplitude of the sound wave. A larger amplitude produces a louder sound. Decibels (dB) are used to measure loudness on a logarithmic scale.
The loudness of sound is determined by the amplitude or intensity of the sound wave. Greater amplitude or intensity results in a louder sound. The unit used to measure loudness is decibels (dB).
