Increase Noise Isolation

Here are a couple of additional molding tips to help improve sound isolation:

• Use the foam tips for maximum noise isolation - if you are using the foam and still need additional isolation, move up to a larger size than what you are currently using. 
  • Compress the foam tips with your fingers, to as small as possible, before being inserted into the ears. This will allow the foam to expand in the ear canal for maximum noise isolation. This also prolongs the life of the foam tips

• Use a bite block while molding—this opens the ear canals and allows the material to get a little deeper

  • A bite block is anything that you can put between your back top and bottom teeth that holds your jaw open about an inch

• Mold as instructed and let cool for one minute; then gently press into the ear again and let cool for the full five minutes

• Angle the tip into the direction of the canal as you're pushing the mold into your ears

  • Each ear canal (R and L) can be a different size, what size of tip that works on one, might not work on the other. Try different tip sizes and combinations of types of tips in each ear, if needed.
