Disposable And Reusable Ear Plugs Testing The Ear Canals Fit Or Not

- Aug 29, 2018 -

Testing the Fit:


The degree of noise reduction that the ear plugs provide depends upon 


proper insertion. Improper fit will reduce their effectiveness. The 


plugs noise reduction can be tested subjectively by pressing firmly 


cupped hands over the ears while listening to a steady noise. If the 


plugs are properly inserted, the noise levels should seem nearly the 


same whether or not the ears are covered.
