Sound and Tectonics

Front

What is sound?

Back

Sound is a type of energy produced by the vibration of objects, traveling in waves through mediums like air, water, or solids.

Front

What type of wave is sound?

Back

Sound is a longitudinal wave.

Front

What is the human hearing range?

Back

The average human can hear sounds in the frequency range of about 20 Hz to 20,000 Hz.

Front

What are infrasonic sounds?

Back

Frequencies below 20 Hz, typically not heard by humans but can be felt as vibrations.

Front

What are ultrasonic sounds?

Back

Frequencies above 20,000 Hz, which humans cannot hear but can be detected by certain animals.

Front

How do sound waves propagate?

Back

Sound waves propagate through mediums by causing molecules to vibrate, creating compressions and rarefactions.

Front

What influences the speed of sound propagation?

Back

The medium and temperature influence the speed of sound propagation.

Front

What is wavelength?

Back

Wavelength is the distance between two similar points in a wave, like from one compression to the next.

Front

What is the relationship between amplitude and loudness?

Back

The amplitude of a sound wave is directly related to its loudness; larger amplitude results in louder sound.

Front

What is frequency?

Back

Frequency is the number of complete cycles of a sound wave that occur in one second, measured in hertz (Hz).
