3. Instruction for insertion depth
For adults, the average length of the ear canal has been estimated to be
23-28mm and the maximum insertion size of the hearing aid is 9.2mm.
So the distance from the ear tip to the tympanic membrane after wearing
the hearing aid is at least 13.8mm, which is greater than the lower limit of
10mm specified by OTC.
Therefore, the device is safe and complies with OTC regulations.
