Standard Pre-bent Earmould Tubes for BTE (Behind the ear) Hearing Aids
For earmoulds used with BTE (behind the ear) hearing aids the quality of tubing is very important.
For high powered aids the tubing should be thick-walled with a hole diameter of 2mm.
Use of standard tubing on high powered aids may cause feedback.
Earmoulds need to be re-tubed regularly. Replace the earmould tubing as soon as it begins to harden.
It is surprising how much the tubing can affect the sound quality.
All Behind The Ear (BTE) hearing aid tubes harden and should be changed at least every six months. Many people find it beneficial or necessary to change them more frequently. BTE hearing aids become uncomfortable and more difficult to wear as the tubes become progressively stiffer. Also, it is claimed the sound transmission through hearing aid tubes deteriorates as the tubes harden.
*What Makes Tubes Harden? Oil from the skin and products used on a person’s hair cause tubes to harden. Additionally, people who spend more time outdoors find their tubes need changing more frequently because the UV rays from sunlight and extremes in temperatures cause tubes to harden faster.
* All the tubes in this listing are industry standard size #13 and fit most BTE hearing aids for adults. This Outside Diameter and a name describing the wall thickness are commonly used to identify the different tubes. The descriptive names and Outside Diameters (O.D.) of the tubes referred to in this listing are as follows:
Normal Wall-0.118” or 3.0 mm O.D.
Medium Wall – 0.122″ or 3.2 mm O.D.,
Thick Wall- 0.138” or 3.5 O.D.
Notice*** Tubes that have been modified, installed, attempted to be installed, have come in contact with a personal hearing aid or earmold or used in any way CANNOT be returned for exchange or refund because we cannot resell Personal Healthcare Consumables.
