Study Notes
Sound Waves Overview
- Sound waves are characterized by two main properties: frequency (pitch) and amplitude (loudness).
Frequency (Pitch)
- Measured in hertz (Hz), representing the number of waves per second.
- Average human hearing range: 20 Hz to 20,000 Hz.
- Acute human hearing sensitivity is typically between 1,000 Hz and 3,000 Hz, where human ears are most responsive.
Amplitude (Loudness)
- Indicates the intensity of sound waves, measured in decibels (dB).
- Average sounds in everyday life, such as conversational speech, measure around 60 dB.
- Sounds at or above 80 dB can cause potential hearing damage.
- Extremely loud environments, like rock concerts, can reach levels up to 120 dB.
