Influence and risk factors on hearing of customer service staff wearing headphones in a park in Wuhan City
Objective To understand the influence of headphones on the hearing of customer service staff,and further explore the influencing factors of hearing loss.Methods By the convenient sampling method,173 customer service staff from a park who visited the Otolaryngology Head and Neck Surgery Department in Renmin Hospital of Wuhan University,from October 2021 to March 2023 and conducted hearing detection through publicity were selected as the observation group.According to the years of use of headphones,they were divided into three subgroups:36 people in the 0-＜3 year group(72 ears),51 people in the 3-＜5 year group(102 ears)and 86 people in the ≥5 year group(152 ears).52 civilian workers who were not exposed to occupational hazards in the observation group enterprises were selected as the control group.The hearing status of the four groups was compared,and the risk factors for hearing loss were explored.Results The results of pure tone audiometry showed that 14 out of 173 people in the observation group experienced varying degrees of sensorineural hearing loss,accounting for 8.2％of those examined.There was no statistically significant difference in each frequency between the 0-＜3 years group and the control group(P＞0.05).There were stati stically significant differences in the hearing threshold at 2.0-8.0 kHz between the 3-＜5 years group and ≥5 years group in the observation group and the control group(P＜0.05).There were statistically significant differences in hearing threshold among different subgroups in the observation group(all P＜0.05).The top two highest percentage of self-reported symptoms and hearing conditions of customer service personnel were"sometimes they could hear their coworkers talking but could not hear what was being said clearly"(36.41％),and"tinnitus"(35.26％).The hearing damage was related to the volume of headphones used,and the difference was statistically significant(P＜0.05).The number of hearing-impaired ears increased in the observation group as the frequency rose,and the number of impaired ears in the 3-＜5 years group in the observation group was more than that in the≥5 years group,which may be related to the use of headphone volume ≥70％per day.Conclusions The use of earphones by customer service staff mainly causes high-frequency hearing loss,and may also lead to decreased speech recognition rate and tinnitus.The use of headphones by customer service staff for ≥3 years,and the volume ≥70％are risk factors for hearing loss caused by the use of headphones by customer service staff.
