Distortion product otoacoustic emissions to single and simultaneous tone pairs.
Distortion product otoacoustic emissions (DPOAEs) evoked by single tone pairs and three simultaneous tone pairs were recorded in 60 normal-hearing adult ears. The purpose was to replicate a previous study using the commercially available probe assembly of the Grason Stadler GSI 60 and including ear of presentation in the statistical analysis along with frequency and condition. DPOAE levels were...
متن کاملDistortion product otoacoustic emissions in tinnitus patients.
Tinnitus is a symptom that affects a great number of patients. Its diagnosis, treatment, and follow-up are difficult, owing to its subjectivity. The authors propose the use of distortion product otoacoustic emissions (DPOAEs) in tinnitus evaluation. They studied three groups: controls, having no complaint of tinnitus and normal hearing; group 1, presenting tinnitus and normal audiometry; and gr...
متن کاملThe role of intermodulation distortion in transient-evoked otoacoustic emissions.
Transient-evoked otoacoustic emissions (TEOAEs) are low-intensity sounds recorded in the external ear canal immediately following stimulation by a transient stimulus, typically a click. While the details of their production is unknown, there is evidence to suggest that the amplitude of each component frequency reflects the physiological condition of the corresponding region of the cochlea. Cert...
متن کاملSwept - Tone Evoked Otoacoustic Emissions: Stimulus Calibration and Equalization
of a thesis at the University of Miami. Master’s thesis supervised by Professor Ozcan Ozdamar. No. of pages in text. (53) Otoacoustic Emissions (OAE) are minute acoustic responses originating from the cochlea as a result of an external acoustic stimulus and are recorded using a sensitive microphone placed in the ear canal. OAEs are acquired by synchronous stimulation with an acoustic click or t...
متن کاملDistortion product otoacoustic emissions: comparison of sequential versus simultaneous presentation of primary-tone pairs.
This Grason-Stadler GSI-60 system for measuring distortion product otoacoustic emissions (DPOAEs) allows the examiner to present one set of primary-tone pairs at a time (i.e., sequential presentation), or to present as many as four sets of primary-tone pairs at a time (i.e., simultaneous presentation). The Sequential and Simultaneous protocols were used to compare administration times, DPOAEs, ...
