What is an iros hearing aid?
For clarity, the IROS is an open fitting on the same side as the hearing aid – essentially, an open fit (unoccluded) hearing aid. Many of the topics of this Symposium were devoted to the problem of measurements via couplers used at the time for unoccluded (open) coupling of the hearing aid to the ear.
What is the function of an Earmold?
The earmould’s main purpose is to conduct sound from a behind-the-ear (BTE) hearing aids into your ear. It also helps ensure that the hearing aid rests securely on your ear. A well-fitting earmould helps prevent feedback whistling from the hearing aid by preventing sound leakage.
What is a trench vent?
Trench Vent: A groove or channel along the bottom of the canal. It is used when drainage or discharge from the ear is a problem, or if there is no room to install an internal vent in the canal.
What is a common reason for venting?
In many cases, a vent can lessen that “in a drum” feeling. Vents are most useful when the hearing loss isn’t serious enough that the amplification required would “leak” out through the vent and reach the microphone, causing a feedback loop.
How do vents affect hearing aid performance?
With a vented, occluding earmold, the input sounds may be increased or decreased at the eardrum depending on the vent diameter. With a completely closed earmold, the input is decreased by almost 20 dB in the high frequencies. Less attenuation is noted as the vent diameter increases.
What is a Libby horn?
Libby Horn Tubing. Special tube designed to increase gain over conventional tubing. Ideal when using an analog hearing instrument and fitting a high frequency hearing loss.
How do you spell earmold?
An earmold (also spelled; ear mold, ear mould or earmould) is a device worn inserted into the ear for sound conduction or hearing protection.
What is an occluded ear?
From Wikipedia, the free encyclopedia. The occlusion effect occurs when an object fills the outer portion of a person’s ear canal, causing that person to perceive echo-like “hollow” or “booming” sounds generated from their own voice.

What is the difference between an iros and an occluded mold?
An IROS fitting is not a truly non-occluded mold; instead it is a modification of an occluded style with a very large, open vent which allows low-frequency sounds to enter the canal unaided, while the high frequencies are amplified. By cutting away part of the canal where the vent opening would be,…
