QuestionAnswer
Acoustic reflex the contraction increases the impedance of the middle ear system by increasing the stiffness of the ossicular chain
Azimuth estimation the process of determining the direction on the horizontal plane at which a sound is arriving at the listener.
Binaural localization cues localizations cues created by differences between sounds arriving at the right ear and left ear
Buckling effect
Cerumen earwax
Distance estimation the process of determining how far one is from a sound source
Elevation estimation process of determining the angle between the horizontal plane and the vertical plane from which the sound is arriving.
Interaural related to the difference between ears
Interaural intensity difference the difference in intensity of the sound wave arriving to the left ear and right ear
Interaural phase difference the difference in phase of the sound wave arriving to the left ear and right ear.
Interaural time difference the difference in time of arrival of the sound wave arriving to the left ear and right ear
Localization the process of determining the direction of incoming sound or the location of a sound source in space in terms of its azimuth and elevation
Localization cues the specific characteristics of received sounds that are used to determine the direction of incoming sound.
Middle ear an air-filled cavity called the tympanic cavity or tympanum containing the ossicles
Monaural related to one ear
Monaural localization cues localization cues that are created by the reflection and refraction of sound by the folds, cavities, and ridges of the outer ear.
Ossicular lever the anatomic lever created due to a difference in the length of the malleaus and the length of the incus. Force acting at the incus= 1.15 times bigger.
Otoscope an instrument that has a light and a narrow tip and magnifying lens used for examination of the ear canal and tympanic membrane
Pressure transformer pressure increase that results because of the size of the tympanic membrane and the oval window. Tympanic membrane= 17 times bigger than the oval window.
Transducer a device that changes energy from one form to another
Tympanic cavity an air-filled cavity of the middle ear containing the ossicles
Valsalva maneuver procedure that punches air into the middle ear cavity via the Eustachian tube (popping your ears) forces the Eustachian tube to open and admit ear
