Acoustic Sensitivity of the Saccule and Daf Music
关键词:
摘要: Introduction: The daf is a large Persian frame drum used as musical instrument in both popular and classical music which can induce percussive sound at low frequencies (146–290 Hz) with peaks of up to 130 dBspl. sounds have power distribution the region saccular sensitivity. In view stimulation by humans, we decided use cervical vestibular-evoked myogenic potentials (cVEMPs) evaluate possibility that may disturbing effect on function. Materials Methods: During this case-control study, 18 musicians were compared 20 healthy individuals evaluated audiology department Hamadan University Medical Sciences. Assessment consisted pure tone audiometry, tympanometry, cVEMPs. Results: Multiple comparisons mean cVEMPs hearing loss 250 Hz among three groups (affected, unaffected, normal ears) significant. There no significant differences between all players high-tone 3000 Hz. had bilateral unsymmetrical sensorineural (SNHL), (low-tone loss) notched audiogram (high-tone loss). Eleven decreased vestibular excitability detected abnormal mild (26–40 dBHL) low-tone findings. contrast, others slight (16–25 Exposure related cochlear dysfunction. Conclusion:
