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 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 کاملPreschool Hearing Screenings: A Comparison of Distortion Product Otoacoustic Emission and Pure-Tone Protocols
Distortion product otoacoustic emissions (DPOAE) are sensitive to both sensorineural and conductive hearing losses and have the potential to be used as an effective screening measure across all populations, including children. DPOAE offer a quick and straightforward hearing screening technique for the pediatric population that is not infl uenced by subjective testing and is highly reproducible....
