100
This is the name of the activator tone in AR testing.
What is the RAS -- reflex activating stimulus?
100
The most common probe tone frequency used in clinical settings.
What is 226Hz?
100
Otoacoustic Emissions are present in all individuals with this level of hearing.
What is normal hearing (better than 30dBHL)?
100
The ABR is measured from these placed on the patient.
What are electrodes?
100
Otitis media with effusion results in this type of Tympanogram.
What is a Type B Tympanogram?
200
The Acoustic Reflex elicits the contraction of these two middle ear muscles.
What are the stapedius and tensor tympani muscles?
200
The structure responsible for equalizing pressure and maximizing TM mobility.
What is the Eustachian tube?
200
The cubic difference formula for distortion product otoacoustic emissions.
What is 2(f1) - f2?
200
The most robust wave of the ABR.
What is wave V?
200
In Tympanometry, outer ear pressure is varied from these values.
What is -200(400)daPa to +200(400)daPa?
300
This brainstem level nuclei is the cross over point, where right and left ear information meet.
What is the Superior Olivary Complex?
300
Negative pressure in the middle ear will result in this type of Tympanogram.
What is a Type C Tympanogram?
300
Otoacoustic emissions are generated from these.
What are outer hair cells?
300
Wave I of the ABR represents activity in this.
What is the auditory nerve?
300
Monitoring the facial (or other important cranial nerves) is done using this type of 'monitoring' during invasive surgeries.
What is intraoperative monitoring?
400
Many individuals with normal hearing do not have an Acoustic Reflex Threshold at this frequency.
What is 4000Hz?
400
The point at which the TM vibrates most efficiently.
What is ambient pressure? (When OE pressure = ME pressure)
400
A type of Evoked OAE used in a clinical setting.
What is Distortion Product or Transient Evoked OAEs?
400
This method is used to obtain a robust ABR waveform.
What is averaging?
400
In acoustic immitance testing, these three measurements are made at the plane of the TM.
What is Static Acoustic Compliance, Tympanometry and Acoustic Reflex?
500
This is the range that normal Acoustic Reflex Thresholds fall within.
What is 85-100dBHL?
500
This tool varies air-pressure manipulated in the EAC via tympanometry.
What is the pressure pump?
500
A pathology involving present OAEs but an absent ABR.
What is auditory dyssynchrony?
500
As we increase the presentation level (dBHL) of the ABR stimuli, this happens to the resulting waveform.
What is an increase in amplitude?
500
The ease at which (sound) energy flows through a system (OE to ME, etc.).
What is admittance?
