Study Notes
Frequency Range of Human Hearing
- Human hearing typically ranges from 20 Hz to 20,000 Hz (20 kHz).
Parts of the Ear and Their Functions
- The middle ear components, particularly the ossicles (malleus, incus, stapes), are crucial for sound amplification and transmission.
- Sound transduction occurs in the inner ear, specifically in the cochlea.
Focus of Physioacoustics
- Physioacoustics primarily investigates the physical properties of sound and its biological effects on humans, including the perception and processing of sound.
Transmission of Sound by Ossicles
- The ossicles transmit sound vibrations from the eardrum to the oval window of the cochlea, enhancing sound intensity.
Distortion and Loudness Perception
- Distortion in the hearing system can arise from non-linearities in the auditory pathways, which affects how loudness is perceived by individuals.
Focus of Psychoacoustics
- Psychoacoustics studies the psychological and perceptual aspects of sound, including how humans interpret and experience auditory stimuli.
Role of the Basilar Membrane and Outer Hair Cells
- The basilar membrane vibrates in response to sound frequencies, facilitating the detection of different pitches.
- Outer hair cells amplify sound vibrations and enhance frequency selectivity within the cochlea.
Initiation of Perceptual Experience of Sound in Physioacoustics
- Physical sound waves interacting with the ear structure initiate the perceptual experience of sound by stimulating sensory receptors.
Eardrum Function
- The eardrum (tympanic membrane) serves as the initial receptor of sound waves, converting them into mechanical vibrations for further processing.
