Question

how does atmospheric pressure affect loudness of sound?​

Answer 1

When an object vibrates, it causes slight changes in air pressure. These air pressure changes travel as waves through the air and produce sound. ... In gases, the higher the velocity of sound, the higher the pitch will be (Remember the "Mickey Mouse" sound when people talk after inhaling helium gas
