Impression Guidelines

ACS Ear Impression Requirements:

Your audiologist will most likely know how to take good ear impressions, suitable for custom hearing protection and in-ear monitors. Just to be sure, please mention the following requirements and they’ll know exactly what you mean.

  • Foam otoblocks are preferred (cotton is okay)
  • Up to or beyond second bend in the ear canal – silicone material must reach the otoblock to form full canal detail
  • Full canal, concha and helix information on the impressions
  • Any bumps or holes in the impressions bigger than 2mm will not be accepted
  • 3D ear scans accepted

If you have any further queries please contact the ACS customer service desk on (646) 559 5642.
