The amplitude of a sound wave is a measure of the distance between the rest position and the maximum displacement of the particle from its rest position. It is equal to half the total displacement of a vibrating particle.

Loudness is the human perception of sound wave?

The amplitude of sound waves is what humans perceive as loudness.


How does the amplitude of a sound wave affect its loudness?

The amplitude of a sound wave directly affects its loudness. A higher amplitude results in a louder sound, while a lower amplitude produces a quieter sound. This is because the greater the amplitude, the more energy the sound wave carries, leading to a stronger perception of sound.


Human perception of how much energy a sound wave carries is called?

Loudness. This subjective perception of sound intensity is influenced by factors like the amplitude and frequency of the sound wave.


What does the amplitude of a compressional wave depend on?

Well, I take it you mean a wave in the air, like a sound wave (alternating compressions of air). Volume of a sound wave ( a type of compressional wave) is our perception of its amplitude, the amplitude is a measure in the intensity of the waves, or the amount of variation in air pressure. Our perception of pitch varies with the frequency, or how frequently the alternations in air pressure persist.


What is an amplitude in sound?

Amplitude of a sound wave is the height between the peak (top most part of the wave) and the trough (bottom most part of the wave). So as the wave travels, say on a string, the highest the string or wave moves up minus the lowest the string or wave moves down is the "amplitude" of the wave.


What properties of sound is determined by the strength of the vibrations creating the sound?

The loudness or volume of the sound is determined by the strength or amplitude of the vibrations creating the sound. The greater the amplitude of the vibrations, the louder the sound will be. The amplitude of the sound wave is directly related to the intensity of the sound perceived by our ears.


Volume of a sound wave is equal to the what?

The amplitude of a sound wave is the same as its volume.


How are sound volume and ampitde related?

Sound volume is subjective perception of a sound's intensity. Amplitude is the physical measure of a sound wave's magnitude. In general, higher amplitude sound waves produce louder volumes.


What is the wave in which amplitude changes to create sound?

The wave in which amplitude changes to create sound is called an acoustic wave. As the amplitude of the wave increases, the sound produced becomes louder, and as the amplitude decreases, the sound becomes softer. This change in amplitude is what creates the variations in volume or intensity in sound waves.


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


What kind of wave in which amplitude changes to create sound?

The type of wave in which amplitude changes to create sound is a sound wave. Amplitude is the measure of the changes within the wave.


What is the amplitude of sound wave?

the amplitude of a sound wave is the air around you's temperature and the time of sound timed together. +++ No - the amplitude of any wave is its "height", which in sound is the wave's pressure. Time and temperature are not involved in amplitude.
