Question 1

Name and discuss any two aspects of sound. (8)

Pitch:

Pitch refers to the highness or lowness of a sound and is determined by the frequency of the

sound waves. Higher frequencies result in higher-pitched sounds, while lower frequencies
produce lower-pitched sounds. For example, a whistle produces a high-pitched sound, while a
bass drum produces a low-pitched sound. Pitch is measured in Hertz (Hz), with higher
frequencies having a greater number of cycles per second.

Amplitude:

Amplitude, often referred to as the "volume" of a sound, is a measure of the sound wave's
intensity or strength. It determines how loud or soft a sound is. Larger amplitudes create louder

sounds, while smaller amplitudes result in quieter sounds. Amplitude is typically measured in
decibels (dB). For instance, a rock concert produces high-amplitude sounds that can be very
loud, while a whisper produces low-amplitude, quiet sounds.

These two aspects, pitch and amplitude, play a crucial role in our perception and understanding
of sound in our daily lives.
