Well, the six properties that describe any wave, including sound waves, are its phase, amplitude, frequency, wavelength, speed, and direction of propagation. I'm not sure if by "air is removed" you mean the wave is now in a vacuum or if you mean it has transferred to another medium. If you mean that it's now in a vacuum, all properties of a sound wave have changed, specifically they've changed to 0 since sound can't travel in a vacuum. If you mean that it's now in another medium, the sound wave's speed and direction have changed.
Its a Wave.
You can control sound wave direction, by changing the direction and pressure of air.
The amplitude of a sound wave is perceived as the sound's loudness.
Sound can be changed by altering its frequency, amplitude, or timbre. Changing the frequency of a sound wave affects its pitch, while changing the amplitude affects its volume. Timbre refers to the quality of the sound and can be altered by changing the harmonics present in the sound wave.
Sound wave
frequency or amplitude
The oscilloscope will be measuring the wavelength of the sound wave.
Changing the amplitude of a wave affects the volume or loudness of the sound you hear. A higher amplitude produces a louder sound, while a lower amplitude produces a softer sound.
The wave property that affects the loudness of a sound is amplitude. Amplitude refers to the maximum displacement of particles in a medium from their rest position as a sound wave passes through it. The greater the amplitude of a sound wave, the louder the sound will be perceived by our ears. This is because a larger amplitude corresponds to a greater amount of energy being transferred by the wave, resulting in a more intense sound.
Only the temperature is changing the speed of sound.
Sound intensity is related to the amplitude of the sound wave, which is the measure of the maximum displacement of particles in a medium from their rest position. The greater the amplitude of a sound wave, the higher the intensity of the sound.
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.
