Why Should You Choose Custom-Moulded Over Disposable Earplugs?

Custom Molded Vs. Disposable Earplugs

Custom-moulded earplugs, sometimes called Personalized Hearing Protection, are just as, if not more, effective for the prevention of noise-induced hearing loss as are disposable earplugs. There have not been head-to-head studies of the relative effectiveness, but two major long-term retrospective studies of the effectiveness of hearing loss prevention programs can provide insight.

Choose Custom-Moulded Over Disposable Earplugs Abstract

In 1989 Franks, Davis and Krieg (Franks, 1989) reported that noise-exposed employees of a company that provided Employee noise protection custom earplugs to all of its employees had changes in hearing over a ten-year period that were no different from their non-noise-exposed colleagues and peers.  The company had six facilities around the United States with noise-exposed employees as well as a cadre of employees of similar age and gender who were not exposed to workplace noise. All of the employees studied had been with the company for the ten-year period studied. Audiometric, health and hobby histories, as well as noise-exposure levels were known for all employees. A ten-year segment of the records was used for the analysis.

It was company policy to provide custom earplugs for use at work or home as well as to provide disposable earplugs to employees to use outside of work. Analysis of the data revealed that the changes in hearing that were observed were not due to exposure to workplace noise. Having resolved that and adjusting for age, statistical analysis showed hypertension and diabetes increased the propensity to have worsening hearing for women. For men, the factors were hypertension, diabetes, and use of firearms.

In 2011, Heyer, et al. (Heyer N, 2011- view abstract) reported a retrospective analysis of hearing conservation programs for three foam ear plugs different companies, all of which relied upon premoulded or slow-recovery foam disposable earplugs to protect employees from noise-induced hearing loss.

  1. > Company 1 made automobile body components,
  2. > Company 2 made automotive parts,
  3. > Company 3 was a major food processing company.

 

All of the employees had been at the study sites for longer than the period of time studied. Noise-exposure and hearing protector use histories were established for each employee as were audiometric records including relevant medical and hobby histories. In this study there was not a cohort of fellow non-noise-exposed employees, so the outcome was compared to a standardized set of data (American National Standards Institute, S3.44-1996 (R 2006)). The noise-exposure levels in the three companies studied were similar, as were they to the noise-exposure levels in the Franks, et al. (1989) study. Heyer, et al. found that two factors were associated with changes in hearing: age and noise-exposure level. Because of the strong effects age and noise-exposure level had on the data, it was not possible to assess the influence of other factors.

Had the pre-moulded disposable earplugs been used as effectively as the custom-moulded earplugs, then noise-exposure level should not have been a main effect associated with changes in hearing; with age factored out, noise-exposure level was as much a primary risk as would be expected for the unprotected.

Summer Hearing

Protect Your Hearing This Summer

NOISE TO LOUD Summer activities like concerts, swimming and diving–especially in colder waters, fireworks, and outdoor yard work like mowing can cause damage to the ears and your hearing. In order to protect your ears from permanent damage caused by summer activities, it is important to know what activities to avoid, when to wear protective earplugs, and when to see an audiologist.

Summer Sounds

The average summer sounds: boats, firecrackers and lawnmowers produce decibel levels that can increase or cause hearing loss and tinnitus. Inside the ear are small, delicate hairs that help conduct the noise that constitutes your hearing. Injury to these hair cells comes from exposure, sudden or prolonged, to loud noises like lawnmowers, leaf blowers, and fireworks at close range. Protecting hearing during these activities by wearing protective listening devices can help prevent hearing loss now and into the future.noisy fireworks

Exposure to loud noise can also cause temporary or permanent tinnitus. Tinnitus is defined as a nagging buzzing, whistling, whining, or screeching noise in head or ears that varies in intensity and can be intermittent or constant. Some tinnitus sufferers describe the noise as being as piercing and sharp as the signal used in the emergency broadcast system. An audiologist can create custom made ear protection that allows a person to hear while simultaneously protecting the ears.

Earplugs

Protecting your hearing this summer can be as simple as wearing custom earplugs when mowing, attending concerts, working with machinery or engaging in other noisy activities. Earplugs for water sports and activities can keep water from the ears, protecting your ears while helping to prevent your body reacting to cold water conditions through exotosis. An audiologist can provide custom fit protective molds for your ears. Custom fit means more comfort and a greater chance of use like communication, but that’s not the only reason to see an audiologist.

Regular checkups with your audiologist are as important as regular checkups with your eye doctor. Your sense of hearing is a precious gift that needs to be maintained through proper care and prevention. Summer sounds and activities damage hearing, so take precautions and see an audiologist to head off any hearing health problems before they happen.
