Sound Sensitivity of the Saccule for Low Frequencies in Healthy Adults

摘要: Approximately 80 years ago John Tait speculated about a possible auditory role for the otolith organs in humans those days, there was no direct evidence that idea. This time is us to review and research. Then, objective of our study investigate saccular hearing healthy adults. We selected twenty controls twenty-four dizzy cases. Assessment comprised audiologic evaluations, cervical vestibular evoked myogenic potentials (cVEMPs), recognition spoken phonemes white noise (Rsp wn). In case group (a total 48 ears), cVEMPs abnormalities were all unilateral (24 affected ears 24 contralateral unaffected ears). Affected with decreased excitability as detected by abnormal had Rsp wn (), whereas both () control presented normal results. The correlation between RSP p13 latencies significant (, ). peak-to-peak amplitudes showed n23 concluded presence severe competing noise, saccule has facilitating cochlea can improve detection loud low-frequencies.
