Auditory deficits in employees of business process outsourcing (BPO): Need to take preventative action

Abstract

The present study aimed to explore auditory deficits in full-time call center workers. A total of sixty participants participated, which was divided into two groups, viz. experimental group and control group. The complete audiological test battery was performed. On comparing the groups, significant differences were obtained for both ears while analyzing the TEOAEs, PTA1, and PTA2 (high-frequency audiometry). From the results, it can be delineated that BPO employees are at risk for sensorineural hearing loss following continuous noise exposure. We conclude that this type of hearing loss may be considered an iceberg, and to overcome all the issues related to noise exposure, all BPO employees should undergo periodic audiological, psychological, and health screening.
