A sound wave with high sound pressure (amplitude) or high sound particle displacement (amplitude) is a sound wave that has a high loudness.
it is called a node.
a crest
The high point on a sound waveform is the point of maximum pressure, the pressure peak.
Shock waves
the alternating areas of quickly moving high and low pressure
The less dense areas created as a sound wave propagates are called rarefactions.
the top of a sound wave is a crest
The high point on a sound waveform is the point of maximum pressure, the pressure peak.
Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
Shock waves
No. A sound wave is a pressure wave.
An ultrasonic wave is a sound pressure wave that has a very high frequency. The frequency is higher that what humans can hear.
the alternating areas of quickly moving high and low pressure
Loudness increases with increasing amplitude of the sound wave, also called increasing sound pressure.
It is called pitch.
how is the pressure varition in a sound wave amplified in human ear
The less dense areas created as a sound wave propagates are called rarefactions.
The region of compression is where all the particles of the medium are closer to each other than usual. In a sound wave that usually means that the pressure in that area of compression is slightly greater than the mean pressure of the material in which the sound wave is traveling.
The pressure wave, created by systole is called a pulse
