About the Thin Tube Molds
The numbers TT1 through TT4 relate to the degree of loss,
and the necessary gain. As the number gets larger, the fitting
becomes more closed and the amount of possible gain increases.
Reasons for Thin Tube Fittings
To better achieve the patient’s goal, it’s helpful to identify the reason for a Thin Tube fitting.
Retention: The dome or fitting piece provided by the manufacturer won’t stay in the ear canal because of:
imperfect size of dome
lack of retention in the canal
length restrictions of the tubing
Feedback: feedback is still a concern with the dome attachment.
Occlusion: occlusion is still a concern, and even with the custom product, there may still be some need for modification. (This was previously not possible with the dome!)
We’re more than happy to help answer all your questions about Thin Tube earmolds before, during, and after the fittings. Please give us a call!
