Hearing
Wavelengths: The distance between corresponding points of successive waves.
Amplitude: The intensity of a sound wave, experienced as loudness.
Cochlea: A structure in the inner ear that converts sound vibrations into neural signals.
Place Theory: The theory that we hear high-pitched sounds because different frequencies activate different locations along the basilar membrane.
Volley Theory: The theory that groups of neurons work together by taking turns firing to detect higher-frequency sounds.
Frequency Theory: The theory that the rate of neural firing matches the frequency of a sound wave, helping detect lower-pitched sounds.
Conduction Deafness: Hearing loss caused by problems conducting sound through the outer or middle ear.
Sensorineural Deafness: Hearing loss caused by damage to the cochlea or auditory nerve.
Cochlear Implant: A device that converts sound into electrical signals that stimulate the auditory nerve.
Sound Localization: The ability to determine where a sound is coming from.
