英文摘要 | Otoacoustic emissions (OAEs) are soft sounds generated by the inner ear and they have been widely used for hearing loss screening in the clinic. However, there are limitations in current methods of clinical OAE measurements, such as the restricted frequency range and low efficiency. In this study, a new method of OAE measurement which used swept tones with time-varying frequencies to evoke one type of OAEs, the stimulus frequency OAEs (SFOAEs), was developed to overcome the limitations. The swept-tone SFOAEs were generated with a three-interval experimental paradigm and extracted by a dynamic tracking filtering technique. The results showed the swept-tone SFOAEs could be successfully measured in high resolution and full frequency range within very short time. The amplitude and phase of the swept-tone SFOAEs were reliable in repeated measures and compatible with traditional methods. Moreover, results showed that the swept-tone SFOAEs were capable of specifying the precise frequency range of the hearing loss. The method of swept-tone SFOAEs may be an alternative of current clinical OAE measurements to provide more detailed and accurate information for hearing loss screening and hearing diagnoses. |
