Across
- 3. In hearing, the theory that links the pitch we hear with the place where the cochleas’s membrane is stimulated
- 7. The sense or act of hearing
- 8. The number of complete wavelengths that pass a point in a given time
- 9. In hearing, the theory that the rate of nerve impulses travelling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch
- 11. A less common form of hearing loss, caused by damage to the mechanical system that conducts sound waves to the cochlea
Down
- 1. The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs
- 2. Hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerves; the most common form of hearing loss
- 4. A tone’s experienced highness or lowness; depends on frequency
- 5. A coiled bony, fluid-filled tube in the inner ear; sound waves travelling through the cochlear fluid trigger nerve impulses
- 6. The chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibration of the eardrum on the cochlea’s oval window
- 10. A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
