Basic Sound Principles

Question 1

Frequency (pitch)

Answer 1

We perceive it as the pitch of a sound. It’s the cycles
per second of a sound wave, measured in Hertz. The faster the rate, the higher the frequency.

Question 2

Amplitude (loudness)

Answer 2

Measurement of the height in the sound wave

Question 3

Reflection

Answer 3

When a sound wave strikes a hard surface, it changes its direction and goes back to the same medium. The angle of incidence is equal to the angle of reflection of sound.

Question 4

Propagation of sound

Answer 4

The transmission of sound waves through different mediums such as air and water can affect the speed and direction of the waves.

Question 5

Speed

Answer 5

The distance travelled per unit of time by a sound wave as it propagates through an elastic medium
