Hearing Protection

Custom hearing protection is:

  • Comfortable – made to fit the user’s ear
  • Easy to insert – just slides into the ear
  • Accurate – since they cannot be worn “wrong,” they always give the same attenuation
  • Good retention – they will not fall out or move around in the ear
  • Sanitary – can be washed and sterilized; no need to handle the canal portion of earmold with dirty hands
  • Visible – can be made in safety orange or royal blue colours to be easily recognized by supervisors (other colours are also available)
  • Cost-effective – average life is two years

Types of Custom Hearing Protection:

Musicians Earplugs™

  • Replicate the natural response of the ear canal so that sound heard with these earplugs has the same quality as the original, just quieter
  • Sound quality of speech and music is preserved so it sounds natural, not muffled
  •  3 Different attenuator filters are available (ER – 9, 15 & 25).  The number corresponds with the amount of sound reduction provided in dB.
  • Non-Custom ear plugs for musicians are available from Limestone Hearing Care Centre and are very inexpensive.  These plugs provide 12 dB of protection


  • Maximum noise protection
  • Use where there is no need to hear or preserve sound
  • Commonly used in industry and recreational activities


  • Good for low frequency noise not over 105 dB with intermittent high frequency noise over 105 dB (carpenters and railroad workers and shooters)
  • Similar to “Sentinel” with a sound bore drilled through the mold with a small filter

Sleep Molds

  • A smaller version of the “Sentinel” mold made to fit comfortably in the ear while sleeping to reduce intruding noise from outside or inside your home – like the person beside you snoring!!
