In this episode, we talk about hearing conservation, sound surveys, dosimeter testing, and hearing protection in a way that feels practical, honest, and real. A good hearing conservation program is not just about handing out earplugs or checking the OSHA compliance box — it is about understanding the actual noise employees are exposed to, choosing the right hearing protection PPE, and making sure the program works for real people doing real jobs.

We cover common gaps that can affect a company’s hearing program, including wireless earbuds worn under earmuffs, off-the-job noise exposure from concerts or sporting events, poorly timed audiogram testing, dirty work environments that affect PPE use, and the risk of overprotecting employees in areas where hearing protection may not be needed. The goal is simple: protect people’s hearing without creating new safety problems along the way. 

Key Points

•  A strong hearing conservation program should include accurate sound surveys, dosimeter monitoring, proper hearing protection, and consistent audiogram testing. 
• Sound surveys and noise dosimeter testing need to reflect real work conditions, including different shifts, tasks, equipment use, cleanup, blow-off, and production changes. 
•  Wireless earbuds under earmuffs can create hidden noise exposure because employers cannot control how loud employees are listening to music, podcasts, or other audio. 
•  Off-work noise exposure — like concerts, football games, rodeos, monster truck rallies, hunting, or shooting clays — can affect hearing test results, especially if audiograms are scheduled too soon afterward. 
•  The right hearing protection PPE is not always the highest-rated option. It needs to match the actual noise level, job task, comfort needs, hygiene concerns, and employee use. 
• Noise Reduction Rating, or NRR, matters when selecting earplugs or earmuffs, but overprotecting employees can make it harder to hear alarms, radios, equipment, forklifts, or coworkers. 
•  Hearing protection should be practical. If PPE is uncomfortable, dirty, hard to use, or not realistic for the job, employees may wear it incorrectly or avoid using it altogether. 
•  Calibration matters. Sound meters and dosimeters need to be properly calibrated so the data behind the hearing conservation program is reliable. 
•  Engineering controls should be considered whenever possible to reduce workplace noise before relying only on PPE. 
•  The heart of a good hearing program is protecting people’s hearing for life — at work and beyond.
