What determines how high or low a sound is?

How high or low a sound seems to a listener is its pitch. Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for humans to hear.

What makes a loud low pitched sound?

The sound an object makes changes depending on how fast it is vibrating. When an object vibrates quickly, high-pitched sounds are heard. Low-pitched sounds come from things that vibrate more slowly.

What tells how loud a sound is?

Loudness of sound is measured in decibels (dB). This is actually a measure of intensity, which relates to how much energy the pressure wave has. Decibels are a relative measurement. They relate the intensity of a pressure wave to a normal or standard pressure.

How loud is a normal conversation?

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

What does a low pitch sound like?

The sensation of a sound wave’s frequency is called pitch. A high-frequency sound, such as a dog whistle, is called “high-pitched,” and a low-frequency sound, like a bass drum, is “low-pitched.” Some pitches, or frequencies, are easier for humans to hear than others.
