If a sound seems to be getting louder which of the following is probably increasing intensity frequency wavelength or speed and sound?
The sound will get louder when the amplitude of the sound pressure increases. The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.
What quantity depends on the speed of sound?
Mach 1 is the speed of sound. Mach 2 is twice the speed of sound... and so on. The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
Why does sound travel faster at the bottom of a mountain than it does at the top?
Speed of sound in air is dependent on the air pressure, and air pressure is dependent on height above sea level. Up high, pressure is lower and speed of sound is different.
What is speed of sound in meter per second?
The speed of sound is dependent on the temperature and not on the air pressure. At 20 degrees celsius the speed of sound is 343 m/s.
When air speed decreases what does air pressure do?
Speed of sound has really nothing to do with atmospheric pressure. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
How did pressure effects the sound when temperature is constant?
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.
How does air pressure effects a sound wave?
The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).

What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
How the amount of air pressure effects a sound wave?
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.
Is sound produced when there are increases in pressure or oscillations in pressure?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
What is the relationship of speed of sound to the atmospheric pressure?
There is a relationsship of speed of sound to the temperature but not to the atmospheric pressure.
The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Did pressure greatly affect the peed of sound in the air?
No. Speed of sound is independent of pressure.
What quantity depends on the speed of sound?
Mach 1 is the speed of sound. Mach 2 is twice the speed of sound... and so on. The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
What happens to a Harrier when it travels faster than the speed of sound?
There are different variations of Harriers in service, the fastest has a top speed of 735mph(.96mach) slower than the speed of sound.
What is the effect of pressure and speed in sound waves?
Speed affects the frequency and pressure affects the wavelength.
