Describe how the human ear perceives sound.
Description should include
- the structure of the ear
- auricle (i.e., outer ear)
- middle ear
- cochlea (i.e., inner ear)
- that sound arrives at the ear as a mechanical sound wave traveling through air
- the frequency range of average human hearing (i.e., 20 hertz [Hz] to 20 kilohertz [kHz])
- the psychological responses to sound that are altered by the environment
- the physiological effects of sound on the human body.
Process/Skill Questions:
- How does the science of sound translate to workplace readiness?
- How does auditory processing from the eardrum to the auditory cortex affect the emotional, mechanical, and reactionary responses to audio productions?
- How are speech and music signals transformed from physical activity in the environment to sensations in the cochlea and psychological perceptions in the brain?
