Study Notes
Sound Wave Frequency Range
- Human auditory perception is typically limited to sound waves ranging from 20 Hz to 20 kHz.
- Sounds below 20 Hz are considered infrasound and are generally inaudible to humans.
High-Frequency Sound Waves
- Sound waves that exceed 20 kHz are classified as ultrasound.
- These high-frequency sounds are used in various applications, including medical imaging and industrial testing.
Interdisciplinary Science
- Acoustics is the interdisciplinary science that explores mechanical waves in gases, liquids, and solids.
- This field encompasses the study of vibration, sound, ultrasound, and infrasound.
Acoustics Scientist
- A scientist specializing in the study of acoustics is referred to as an acoustician.
- Acousticians engage in research and application to understand sound behavior and its effects.
Role of Audio Engineers
- Audio engineers focus on the technical aspects of sound, including recording, mixing, and mastering audio.
- They are concerned with sound quality, manipulating audio signals to achieve desired outcomes in various media.
