Hearing Aid Earmolds
The first step in using hearing aid earmolds is taking an impression of your ear canal. The next step is creating a mold. Once you have your mold, you can make a decision on the type of hearing aid earmolds that are best suited to your needs. There are two types of earmolds: hard and soft.
People who are prone to outer ear infections (otitis externa) or have perforated eardrum or myringotomy tubes should use swim molds when exposing the head to water.
Creating a tight acoustic seal
One of the most important aspects of hearing aid earmold design is creating a tight acoustic seal. This allows the wearer to avoid exposure to damaging noise levels. This seal is achieved by selecting the right material for the hearing aid earmold.
There are two kinds of molds available to create a tight seal. The first is the shell mold, which resembles the receiver mold but is made with a belled receiver plate. Its seal is excellent and will work for most cases. Another type is the half-shell mold, which is convenient to insert and remove. Both of these molds offer a good acoustic seal and retention in the ear.
Another type of mold is made with silicone. This material is hypoallergenic, which is helpful for people with allergies. However, the silicone in earmolds may not be right for every person. If you are unsure about how to insert earmolds, your audiologist will walk you through it step-by-step. While the process can seem strange, it is not painful and will not make you feel uncomfortable or groggy.
Each mold captures a person’s unique ear shape and size.
Taking an impression of your ear canal
Taking an impression of your ear canal is a necessary step in fitting a hearing aid. The impression will last a few minutes and is performed by a hearing health professional. He or she will also check your ears for wax and debris. If they find any, the hearing health professional will remove it.
A large syringe or impression gun is used to take the impression. A material will be dispensed into your ear canal up to the otoblock. The tip of the syringe or canula should be inserted into the external ear canal. The material should be filled up to six millimeters.
Hearing healthcare professionals usually take an impression of your ear canal when you first use a hearing aid. This impression is important because the earmold will be custom-made for your ears. You may experience some discomfort while wearing a hearing aid, but this is completely normal and is necessary for proper use of the device.
Creating a mold
Creating a mold for hearing aids is a critical step in the process of custom fitting hearing aids. It allows an audiologist to create a product that is precisely shaped and sized to your ears. The process is painless, and requires little time on your part. Your audiologist will insert a protective foam or cotton block in your ear and then apply a molding material. This material hardens in a matter of minutes. The audiologist will then send the impression off to a lab for manufacture.
A mold for hearing aids can be difficult to create if there is a buildup of earwax or skin flakes in the ear canal. It’s also important to make sure your hearing care professional has ruled out any ear problems before creating a mold.
Because no two ears are the same, earmolds must be custom-fitted to each person’s ears. No two molds are exactly the same size or shape, so you must be sure to discuss the shape and size of your ears with your audiologist. Custom fitting earmolds ensure maximum comfort and optimal performance for your hearing aids. The proper fit can reduce feedback and screeching noises.
Soft vs. hard earmolds
The main difference between hard and soft hearing aid earmolds is the material they are made of. Vinyl earmolds are generally made of polyvinyl chloride (PVC), a material that is particularly well-suited for soft ears. The materials of this type provide better acoustic seals and stay in place without the use of glue. However, they can be difficult to adjust and are susceptible to hardening and turning yellow or brown if exposed to sunlight.
When choosing an earmold, the type of material should be dependent on the patient’s hearing loss and the type of hearing aid. The earmold material is also important because the earmolds should be able to fit deep inside the ear canal without sliding out. The choice of material also depends on how sensitive the ear is, the level of hearing loss, and the desired appearance of the hearing aid.
Soft earmolds are often made from polyethylene, which is a semi-hard wax that can be easily molded, but has some limitations. Polyethylene can cause allergic reactions in some people and is less cosmetically appealing. In contrast, silicone is flexible and provides a good fit. Silicone is also very durable and is often the material of choice for hearing aids.
Creating a semi-skeleton mold
There are two common mold types used for hearing aid earmolds. The open skeleton mold and the half-shell mold. The former is more forgiving and comfortable, while the latter is more rigid and offers good retention. The latter is used for BTE hearing aids, and is similar to a full mold but without the center part.
Creating a semi-skeleton mold requires a great deal of planning and preparation before a patient can actually try on the earmold. The process requires the patient to fill out a form that provides specific information about the patient’s ears and the final product that the patient wants. This information includes the style and material that the earmold should be made of, as well as the venting that should be used. In addition to this information, the patient’s hearing loss must also be stated on the form.
If the concha area of the ear is unusual, the semi-skeleton mold can help to achieve a comfortable fit. Semi-skeleton molds are also easy to retain. These molds are designed for mild to moderate hearing losses, and are also the most suitable for people who are concerned about appearance.
Silicone vs. plastic earmolds
When choosing a hearing aid earmold, you have several options. Silicone earmolds offer a comfortable and secure fit, and are more resistant to tearing and breaking than plastic earmolds. However, silicone is not as cosmetically appealing as plastic, and it’s difficult to modify. Plastic earmolds can be difficult to fit into your ears, and some patients may be allergic to plastic or acrylic.
Earmold materials are also important to consider. Hard earmolds tend to be more flexible and don’t require a complete seal on the ear canal. Instead, they can be fitted to only fill the anterior portion of the external auditory meatus, leaving the remainder of the ear open. The type of hearing aid you choose will determine which type of earmold you need.
Hearing aid earmolds are an important component of hearing aids. Whether you want a hard or soft one will depend on your personal preference. The choice will depend on your hearing loss and the size and shape of your canal.
Conch vs. canal earmolds
When it comes to hearing aid earmolds, the two main options are conch and canal styles. Conch earmolds sit in the bowl of the ear, while canal earmolds fit inside the ear canal. These styles vary in appearance, and both are suitable for people who have mild to severe hearing loss.
The main difference between canal and conch earmolds is the material used to make them. Canal-fitting earpieces are made of silicone or acrylic. In contrast, conch-fitting earpieces are made with a softer material, such as silicone.
While both styles have their benefits, they do have some drawbacks. One drawback is that the earmold may not fit properly. The ear is unique to every person, and the earmold should fit properly to provide optimal hearing support.
Conch earmolds are designed to be more secure. They can be vented the same way as canal-style earmolds. Moreover, some molds are made with concha locks, which prevent the earmold from moving out of the canal.
Non-occluding hearing aids are very similar to occluding earmolds, but they have two key differences. Non-occluding hearing aid models have a smaller canal portion and a larger vent for air circulation. This design allows for more comfortable sound quality and a better overlay of amplification over natural hearing.
Non-occluding hearing aids are available in several styles and colors. Their style and material can be customized to match the patient’s clothing or skin tone. For a discreet appearance, the earmold’s style should be appropriate.
Non-occluding hearing aids come in two shapes, dome and full-shell. Dome style earmolds look like a small cone. The size of the dome is determined by the shape of the individual’s ear. The openness allows natural sound to pass through and allows the aid to ventilate properly. Both types are available in several sizes, including custom-made earmolds.
Earmold styles are available in different styles and types, based on your level of hearing loss and the anatomy of your ear. Custom-made earmolds are usually more comfortable and offer better retention than universal domes. Custom-fit earmolds also come in basic styles. These can be used with almost any hearing aid. The main difference between these two styles is the bore size.
A BTE hearing aid is worn behind the ear, and transmits sound to the earmold via a thin, flexible tube. Earmold Styles: Earmold styles vary according to level of hearing loss, and the style of hearing aid with which they’re paired.
