mismatch & Protects from loud sounds (also, Eustachian tube equalizes pressure BC for the TM to vibrate, the air pressure needs to be equal on each side of the TM.) INNER: amplify sounds, frequency selectivity, converts sound to electrical signal, maintain balance Function of outer and inner hair cells? - answerOUTER: Amplification of displacement on the traveling wave & frequency selectivity (active processes are here) INNER: Nerve excitation= send signals to auditory nerve What are the f...

What is the relationship between fundamental frequencies and harmonics? : F0= lowest freq component of a complex periodic sound; harmonic is a regular and repeating multiple of the f0 In which frequencies and at what intensities are most speech sounds produced? : When applied to speech, the human voice spans a range from about 125Hz to 8kHz. 55-65 dB Define threshold : "Threshold is defined as the lowest decibel hearing level at which responses occur in at least one half of a series ...
