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 its source?
The energy in the sound's vibration dies down, until it is no longer audible.
What property of sound describes your awareness of the energy of a sound?
loudness
What determines the loudness of a sound wave?
The amplitude determines the loudness of a sound wave.
What is the loudness of sound also known as?
The loudness of sound is also known as volume.
Is the loudness of a sound is called its intensity?
Yes the loudness of a sound is called its intensity.
Why does the loudness of a sound wave decrease as the wave travels away from it source?

The amplitude determines the loudness of a sound wave.
What determines the loudness of sound waves?
The amplitude determines the loudness of a sound wave.
Loudness is the human perception of sound wave?
The amplitude of sound waves is what humans perceive as loudness.
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.
What does the amplitude of a wave tell about a sound?
Amplitude is the maximum displacement of a wave. The amplitude determine the loudness of the sound
On what factor the loudness of sound depend upon?
The loudness of a sound depends on the amount of energy it takes to make the sound and the distance from the source of the sound.
How does amplitude affect the loudness of a sound?
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
