The intensities of traveling waves, which includes sound, light, etc., are measured in units of power divided by area. That is, watts per square meter (W/m2 ) or watts per square foot (W/ft2), or any combination of units which is equivalent.

How are loudness and and intensity related to the amplitude and energy of a sound wave?
The word loudness belongs to psycho acoustics and tells how we feel this sound, that is not measuring the sound like we do with a sound pressure meter. Listening to music means motion to the ear drums. Only sound pressure moves the ear drums. The energy or the sound intensity is much less important here. Sound intensity belongs more to the noise fighters.
What property of sound depends on the energy and intensity of the sound wave?
Its volume or how loud it is.
How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
What is the unit used to measure the relatice intensity of sound?
Your ears and the sound pressure level meter "measure" the sound pressure of a sound wave. Sound intensity is measured in watts per square meter.Intensity is measured in watts per square meter.Note: Sound power (sound intensity) is the cause -and the sound pressure is the effect.The effect is of particular interest to the sound engineer.
Where could a person buy a sound wave measuring device?
You could buy a sound wave measuring device at most hobby shops. You might also find them at shops that carry musical instruments. There are also specialty sites online that carry them.
What do we see that the amplitude of a wave produces?
The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
What is the intensity of sound wave called?
intensity level
What is the intensity of a sound wave called?
intensity level
What gives a sound wave its pitch and intensity?
A sound wave's pitch is determined by its frequency; that is its cycles per unit of time. The sound wave's intensity or volume is determined by its amplitude; the maximum crest of a sound wave.
What is the amplitude of a sound wave a measure of?
The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.
What is meant by intensity of sound how it is different from loudness?
loudness is the magnitude of wave of sound(the highest point reached by the wave). intensity is frequency of sound (that's how much a wave vibrates in 1 second)
What is the wave in which amplitude changes to create sound?
The wave in which amplitude changes to create sound is a sound wave. The intensity of the wave will be changed by energy.
How much louder is a sound wave that has an intensity of 50 dB than a sound wave with an intensity of 20 dB?
The power in the wave is [ 30 dB = 1,000 times ] greater.
Sound intensity corresponds to?
wave length
What happens to the volume of a sound wave as its amplitude decrease?
You mean by the word 'volume' the intensity of sound wave. Intensity is directly proportional to the square of the amplitude.
Which wave characteristic is most related to sound wave intensity?
Amplitude (the height of the wave)
What is the intensity of a sound?
Based on the decibal system? On the length of the sound wave
