Objective Some patients with essential tremor （ET） have hearing impairment. However， there are few targeted studies. The objective of this article is to speculate the essential characteristics of ET through the study of the hearing characteristics of ET， and to provide reference strategies for the clinical diagnosis and treatment of ET.Methods A parallel group design was adopted. A total of 73 ET patients （146 ears） and 60 healthy controls （120 ears） from the inpatient and outpatient sections in the Department of Neurology of The Second People’s Hospital of Qujing were enrolled in this study. Mini-Mental State Examination （MMSE） scoring， questionnaire survey， pure tone audiometry （PTA）， and distortion product otoacoustic emissions （DPOAE） were performed， and the amplitude of DPOAE was measured at the same time.Results The questionnaire survey showed that the number of ears with hearing loss in the ET group was significantly higher than that in the control group （P =0.027）. The objective hearing tests showed that the number of ears with hearing loss in the ET group was significantly higher than that in the control group， according to the DPOAE and PTA results （P =0.019 and 0.046）. According to the questionnaires， the incidence of both tinnitus and high-frequency tinnitus in the ET group was significantly higher than that in the control group （P =0.013 and 0.000）. The regression analysis of the correlation between the course of ET and the decreasing amplitude of DPOAE showed that there was a linear correlation between them （r=0.948， P=0.005）.Conclusions Hearing impairment may be another typical non-motor symptom （NMS） of ET. It is speculated that ET may be a neurodegenerative disease. ［Journal of International Neurology and Neurosurgery, 2021, 48(1): 46-49］
