Use blue silicone ear impression material (less expansion) Earmold material: I prefer using a 70 Shore silicone (not too soft as it has to go through the canal at its tightest spot), Canal length: This largely depends on where the narrowest point is. We will cover the first three factors during this course, as earmold acoustics is perhaps an intermediate level course which would require a class of its own. These can be made with a variety of vents and can even be fully occluded, meaning they seal the ear canal completely and allow for optimal sound for those with severe to profound hearing loss.. The thin tube earmold is a great solution for individuals who are concerned with how an earmold appears cosmetically. It is indeed true that many changes to the acoustic parameters of a modern hearing aid can be readily adjusted with a few clicks of a mouse or computer keyboard, using the manufacturers fitting software. The case is connected to an earmold or an earpiece by a piece of clear tubing. The first area of concern is canal length. Pull the ear outward and upward while easing the mold into the ear canal. Fabrics that are woven, have a warp and a weft, and are woven on looms. Preferred: Parallel Routine Hearing Test May Help Diagnose Autism Earlier, RT: For Decision Makers in Respiratory Care. Notice how low frequency gain is affected due to changes in the venting characteristics relative to the sound bore, but high frequency gain is unaffected. One of the likely factors contributing to the disregard of earmold acoustics and how they contribute to a successful fit can be attributed to the popularity of open-canal (OC) technology. The earmold needs to be as inconspicuous as possible within the limits set by the acoustic requirements of the patient. Thus, it is prudent to revisit some of the basic science surrounding earmolds and earmold acoustics, especially as it relates to thin tube/thin wire mini-BTE technology. Kuk4 determined that the canal portion of the earmold contributes the most to maximum gain requirements of the BTE.

Matte - The smooth matte finish helps hide the earpiece in the ear when using clear or one of Westones many skin tone or DisappEar color choices. If the mold is difficult to insert, especially in the helix tip area,to address that issue,you can ask for a reduced helix. A larger earmold concha, an extended helix, or a raised tragus will not prevent acoustic feedback because the concha, helix, and tragus do not contribute to the earmold seal. Attributes related to the ear can play a role in determining which type will work best. Occluding earmolds are designed to seal the ear canal completely. Available in all materials and acoustic modifications. Acoustic dampers (or resistors) remove energy from the frequency response; they decrease the peaks and dips of the freq response. When weare dealing with a tiny ear canal, a tubing anchor may require a larger space. It provides the path between the receiver and the ear canal. The effect of sound directionality and digital noise reduction will go down. The ear impression, using the correct size oto block, must make contact with the entire canal wall, as shown in Figure 1.
