Distortion 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 کامل[Characteristic of distortion product otoacoustic emissions for preterm newborn].
OBJECTIVE To investigate the characteristic of distortion product otoacoustic emissions (DPOAE) amplitude, SNR and noise in preterm newborns. METHOD DPAOEs at the 2f1-f2 frequency were recorded from 59 ears of 31 preterm newborns and 35 ears of 19 healthy fullterm newborns in response to equilevel primary tones at postnatal 3 days to 1 week. Detailed test included the recording of DPAOEs, SNR...
متن کاملComparison of standard and abbreviated distortion product otoacoustic emissions procedures.
Standard and abbreviated distortion product otoacoustic emissions (DPOAEs) procedures derived using the Grason Stadler Model 60 instrument were compared. The standard and abbreviated procedures were compared at frequencies of 1000, 1250, 1593, 2000, 2531, and 3187 Hz for 48 ears from 28 subjects. The subject pool included individuals with normal hearing and those with sensorineural hearing loss...

متن کاملDistortion 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...
