Description
Background: Hearing protection devices (HPDs) are often used in the workplace to prevent hearing
damage caused by noise. However, a factor that can lead to hearing loss in the workplace is improper
HPD fitting, and the previous literature has shown that instructing workers on how to properly insert
their HPDs can make a significant difference in the degree of attenuation.
Methods: Two studies were completed on a total of 33 Hydro One workers. A FitCheck Solo field
attenuation estimation system was used to measure the personal attenuation rating (PAR) before and
after providing one-on-one fitting instructions. In addition, external ear canal diameters were measured, and a questionnaire with items related to frequency of use, confidence, and discomfort was administered.
Results: Training led to an improvement in HPD attenuation, particularly for participants with poorer PARs before training. The questionnaire results indicated that much HPD discomfort is caused by heat, humidity, and communication difficulties. External ear canal asymmetry did not appear to significantly influence the measured PAR.
Conclusion: In accordance with the previous literature, our studies suggest that one-on-one instruction is an effective training method for HPD use. Addressing discomfort issues from heat, humidity, and communication issues could help to improve the use of HPDs in the workplace. Further research into the effects of canal asymmetry on the PAR is needed.
