The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
The peak of a sound wave where the lowest air pressure occurs is called the rarefaction. This is the point where the air molecules are spread out, creating a region of decreased pressure compared to the surrounding air.
A sound wave of high pressure is called a compression or a peak in the wave's amplitude. These high-pressure regions correspond to the portions of the wave where air particles are densely packed together.
The higher pressure part of a sound wave is called the compression phase. It represents the regions of increased air pressure created by the vibration of a sound source.
A region of high pressure in a sound wave is called compression. This is the part where air particles are pushed closer together, resulting in higher pressure.
A sound wave is longitudinal because it travels by compressing and expanding air particles in the same direction as the wave's movement. This creates areas of high pressure (compression) and low pressure (rarefaction) as the wave passes through a medium, such as air.

You can control sound wave direction, by changing the direction and pressure of air.
The low point of a sound wave, where the lowest air pressure occurs, is known as the trough. It is the point of the wave where air particles are farthest apart, leading to decreased air pressure. Sound waves consist of both high and low pressure points as they travel through a medium like air.
The higher pressure part of a sound wave is called the compression phase. It represents the regions of increased air pressure created by the vibration of a sound source.

The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
The energy in a sound wave is related how the air pressure changes as the wave move through the air. A moving object such as a vibrating drum head causes pressure disturbances in the air, which travel away from the object. The higher the pressure difference (between maximum and the 'normal' air pressure) will mean more intense sound (and more energy).
The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure). The speed of sound c = 331.3 + 0.606 × ϑ m/s. At the temperature ϑ = 20°C the speed of sound is c ≈ 331 + (0.6 × 20) = 343 m/s.
Compression happens during the part of the sound wave where the air particles are pushed closer together, resulting in an increase in air pressure. This creates a region of higher pressure within the sound wave, causing the compression of the air particles.
The areas of higher pressure in a sound wave are called compressions. These regions correspond to the parts of the wave where air molecules are closer together, creating areas of increased pressure.
