Study Notes
Sound Properties
- Sound properties are characteristics of sound waves that describe their physical and perceptual attributes
- Examples of sound properties include amplitude, frequency, wavelength, speed, and timbre
Units of Measurement
- Units of measurement are used to quantify sound properties
- Examples of units of measurement include decibels (dB) for loudness, hertz (Hz) for frequency, and meters (m) for wavelength
Auditory Thresholds
- Auditory thresholds are the minimum sound levels that can be perceived by the human ear
- Examples of auditory thresholds include the threshold of hearing (TOH) and the threshold of pain (TOP)
Sound Components
- Sound components are the individual elements that make up a sound wave
- Examples of sound components include frequency, amplitude, and waveform
Sound Descriptions
- Sound descriptions are verbal descriptions of sound properties or characteristics
- Examples of sound descriptions include "loud", "high-pitched", and "raspy"
Measurement Definitions
- Definitions of measurement units provide context for understanding sound properties
- Examples of measurement definitions include "decibel: a unit of measurement for loudness" and "hertz: a unit of measurement for frequency"
