, Frequency - ✔✔Number of cycles (vibrations) per second
Perceived as pitch
Unit of measurement: Hertz (Hz)
Human hearing range in frequency? 20-20,000
High frequency = short wavelength
Low frequency = long wavelength
Amplitude - ✔✔- Maximum displacement in the positive and negative direction
- Perceived as loudness
- Unit of measurement: decibels (dB)
- higher= longer
- lower= smaller/tighter compacted
Human auditory system is splint into: - ✔✔Peripheral and central
Peripheral - ✔✔Outer ( Auricle pinna & EAM)
Middle (Tympanic membrane & ossicular chain & impedance matcher)
Inner ear (Cochlea & Vestibule and semicircular canals- Origin of Corti)
Two mechanisms of hearing: - ✔✔Air conduction
Bone conduction
What is air conduction? - ✔✔sound waves travel from the outer ear, middle ear, to the inner ear.
What is bone conduction - ✔✔vibrations go through the skull, bypass the outer ear and middle ear, directly stimulate
the inner ear
Hearing loss descriptors: case study - ✔✔pre-lingual vs. post-lingual
progressive vs. sudden
