Part of cochlear anatomy responsible for DPOAEs.
What is outer hair cells?
A 3-year-old with chronic ear infections had PE tubes places 3 months ago. The current audiological battery reveals normal hearing bilaterally, and tympanograms reveal large volumes bilaterally. This indicates
What is patent PE tubes
In audiometric testing, a false-positive response means this.
What is the signal was not presented, but the patient responded?
When preforming identification audiometry for school-aged children, this type of signal should be used.
What is pure-tone signal.
Jon, a 45-year-old computer sales representative was treated with aminogylcoside antibiotics for an infection years ago. He now says he has trouble understanding speech, especially in noisy situations, and he complains of tinnitus in both ears. What most likely caused Jon's hearing problems?
What is ototoxicity?
Part of the vestibular system sensitive to vertical linear acceleration
What is the saccule?
The middle-ear system of an infant is mass dominated with a lower resonant frequency, thus this probe frequency is most appropriate for detecting changes in middle ear function during tympanometry.
What is 1000 Hz?
Appropriate test method for a typically developing 3-month old.
What is behavioral observation audiometry?
Studies concur that infants should be approximately this developmental age to successfully participate in VRA tasks.
What is 5-6 months?
OSHA action level at which workers must be included in hearing conservation program.
What is 85 dB A TWA?
A bilateral benign bony growth of the external ear commonly found in persons with a history of cold-water swimming? (Medical terminology)
What is exostosis?
While tympanometry is being performed on a patient, a seal is obtained on the test ear. The volume of the external canal is 5 cubic centimeters. During the tympanometric measurement, the seal is intermittently lost whenever the patient swallows. This is most likely the cause of the problem
What is Eustachian tube dysfunction?
According to the contralateral masked-threshold function shown in the figure about, which of the following values represents the true threshold for the test ear?
What is 75 dB (80 dB also acceptable)?
most babies with mild hyperbilirubinemia are treated with this
What is phototherapy?
90 dBA TWA or OSHA term for level where hearing protection devices are required.
What is Permissible Exposure Limit (PEL)?
Which kind of hearing loss, if any, will most likely result from a head injury involving a transverse fracture of the temporal bone through the otic capsule?
What is a permanent sensorineural hearing loss? (fracture though the cochlea draining fluids)
Elicitation of an acoustic reflex at a hearing level better than that obtained with voluntary behavioral responses suggests the presence of this
What is functional or nonorganic hearing loss (malingering)?
A patient in the early states of Meniere's diseases will have an increase in the amount of endolymph in the inner ear. At the same time, audiometric assessment is likely to show sensorineural hearing loss that primarily affects this frequency range.
What is 250-2000 Hz?
Bacterial meningitis is know to cause this kind of hearing loss in children.
What is sensorineural hearing loss?
Under Occupational Safety and Health administration (OSHA) regulations, a standard threshold shift on an annual audiogram is defines as a change in hearing threshold relative to the baseline audiogram of an average of 10 dB or more at these frequencies.
What is 2000, 3000, 4000 Hz only
Together, the areal ratio of the tympanic membrane to the oval window + lever action of the ossicles provides and increase of about ______ dB SPL in the sound pressure level from about 250-4000 Hz.
What is 22?
Bilaterally absent contralateral acoustic reflexes with bilaterally present ipsilateral reflexes indicates.
What is a brainstem lesion?
With typically-developing children, this is the earliest age at which TROCA and other play audiometric tasks can be implemented.
What is 30 months?
This word-recognition test is most appropriate to use with a 5-year-old child who has otitis media and a severe articulation disorder.
What is the Word Intelligibility by Picture Identification (WIPI)?
A person calls to order tickets for a concert and is told that at the rear of the orchestra section, which is 20 meters from the state, the average intensity is 65 dB SPL. The person decides to purchase tickets for seats that are 10 meters from the state, where the sound-pressure level will average this (dB SPL).
What is 71 dB SPL? (Inverse Square Law: sound intensity decreases by 6 dB when the distance from a sound source doubles.
