Does Shape of a Click Stimuli Play a Role in Transient Otoacoustic Emissions???
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 1
Abstract
The discovery of Otoacoustic emissions (OAE) opened a new dimension in audiological assessment. Transient evoked otoacoustic emissions (TEOAE) have an advantage of being its ease of usage, faster administration, objectivity, non invasive nature and also high sensitivity[2] as compared to other audiological procedures. The present study aimed to compare transient evoked otoacoustic emission response using two different click (rectangular and trapezoid) stimulus shapes. Materials and Methods: A total of 30 ears were considered for the study. 15 normal hearing individuals (7 males and 8 females) with age ranging from 15-30 years served as Participants for the present study. Results: The mean difference between the rectangular and trapezoid shape were 3, 3, 3, 1 and 2dB at the 1, 2, 3, 4 and 5 KHz respectively. The SNR for rectangular shape was better than trapezoid shape. The paired sample t- test results revealed significant differences in TEOAE amplitude for all the frequency. Conclusion: It can be inferred that there is significant difference in TEOAE amplitude for all the frequencies between two different stimuli shape. This difference could be attributed to the broader spectrum that is seen in the rectangular shape as comparison with the trapezoid stimulus. Rectangular shape produced better SNR than trapezoid stimulus shape.
