Abstract

Background: The accurate processing of auditory signals holds significant importance in military occupations and can be adversely affected by exposure to noise.

Objectives: This study investigates the correlation between annual noise exposure (ANE) and military personnel's auditory attention and hearing loss.

Methods: This study assessed 220 military personnel serving in an armored brigade unit. The Noise Exposure Questionnaire (NEQ) was employed to quantify annual noise exposure, while the Dichotic Digits Test (DDT) was used to measure auditory attention. Additionally, the study examined the hearing threshold of personnel across frequencies ranging from 500 to 8000 Hz.

Results: The mean ANE among the personnel was 76.80±7.26 dB, and the average number of correct responses in the Dichotic Digits Test (DDT) was 73.74±4.85. The results of the correlation analysis indicated a significant inverse relationship between annual noise exposure and auditory attention (P < 0.001), as well as a notable direct correlation between personnel's annual noise exposure and hearing loss across all frequencies (P < 0.001).

Conclusions: The results of this study showed that the increase in annual noise exposure has increased the rate of hearing loss in both ears and decreased the auditory attention of military personnel.

期刊介绍： WORK: A Journal of Prevention, Assessment & Rehabilitation is an interdisciplinary, international journal which publishes high quality peer-reviewed manuscripts covering the entire scope of the occupation of work. The journal''s subtitle has been deliberately laid out: The first goal is the prevention of illness, injury, and disability. When this goal is not achievable, the attention focuses on assessment to design client-centered intervention, rehabilitation, treatment, or controls that use scientific evidence to support best practice.
