Occupational Noise-Induced Hearing Loss in a Zumba Instructor: Identification and Management
PM (a 27-year-old female) was referred to our Audiology clinic by a friend in August 2016. PM reported no difficulties communicating in groups or in noisy listening environments. She reported, however, a history of intermittent bilateral “buzzing” after listening to music via headphones for long periods. The “buzzing” lasted only for a few minutes without any noticeable change in hearing. PM presented with excellent health and provided a negative history of otologic diseases. PM has been working as a part-time Zumba fitness instructor for the past 2 years (six classes per week, 45–50 minutes each class). Classes are taught to large groups in a space large enough to accommodate 100 participants.
