Health effects of noise exposure levels among instrumentalists in pentecostal churches in Port Harcourt City, Nigeria

Abstract

Background: Noise is everywhere in our daily lives and becomes very important as it affects our health. Religion is an integral part of daily lives and the use of acoustic and electronic instruments in worship. With the increase in sophistry of these instruments come their attendant untoward effects on the auditory organs of the body. This study was to assess noise exposure levels amongst instrumentalists in Pentecostal churches in Port Harcourt City, Nigeria.

Materials & Methods: Following ethical consideration, 216 consenting respondents from 30 churches in Port Harcourt were recruited by table of random numbers. Structured close ended interviewer administered questionnaire incorporating the Hearing Health Quick Test (HHQT) was used to access demographic data. Hearing assessments were also performed using tonal audiometry. The data were entered and analyzed using SPSS version 20.0 and presented using descriptive and inferential statistics.

Results: Most 90.28% and 37.96% of respondents were male and within the 39-45 year-old age range respectively. Also, 80.56% of respondents were aware that loud music can cause permanent hearing loss. The prevalence of NIHL and Tinnitus was 39% and 38% respectively; and only 19% used Hearing Protection Devices (HPD). Statistically significant risk of NIHL was observed in musicians who had experienced tinnitus, played only amplified instruments and Music experience greater or equal to 10 years (p=0.001).

Conclusion: Gospel instrumentalists are exposed to noise in the course of their duties which have significant effect on their hearing. Use of Hearing Protection Devices (HPD) as a personal protective equipment is encouraged just as health education of this group of workers is necessary.
