If you have a hearing problem and have recently had a hearing test completed, then you may have learned that your hearing ability has reduced significantly over the last few years. If so, then you may want to invest in new hearing aids. However, many newer aids can also be adjusted, thanks to digital technology, to elevate the sounds you hear. In certain cases, digital adjustments may not be adequate and a new hearing aid is required. Keep reading to learn about a few situations that may require a new aid.
Your Ear Molds Are Old
Certain types of hearing aids are made to fit inside your ear. In the ear and in the canal aids are two of the more common types of hearing aids that sit inside the ear itself. The types of aids are personalized and made to fit the specific shape and size of the ear. To get the right fit, your audiologist will use either a methyl methacrylate or a silicone based material in the ear to create the mold.
Over time, the ear can stretch out a bit due to the pressure of the hearing aid on the soft tissues of the ear. When this happens, sounds can seep out from around the edges of the hearing aid and cause feedback, whining, and screeching noises. These noises may not occur when the hearing aid is set at a lower sound level, but they may show up when the hearing aid is turned up a bit.
If feedback issues are noted and you have an inner ear hearing aid, then a new mold will be needed. The aid with the attached shell will then be created for you.
You Have The Wrong Type Of Aid
Hearing issues can often be assisted with the help of any number of different hearing aid varieties. However, severe hearing problems cannot always be helped with in the ear types of aids. The aids typically have vents that allow some of the sound to escape, and this can create feedback. Also, because the microphone and the amplifier sit relatively close to one another, sounds may be picked up by the microphone, regardless of how tight the aid fits into the ear.
If your hearing aid no longer works well for you, then it may be time to switch to a receiver in the ear or a behind the ear variety of aid. Both of these options feature microphones that sit behind the ear and amplifiers that sit in the ear canal. This helps to separate the two parts of the aid so feedback is not such a big concern. You may still want to speak to your audiologist about a hearing aid device with a strong feedback reduction feature though.

I have struggled with allergies my entire life, and my health issues kept me from enjoying playgrounds and outdoor sports like the other kids. When my daughter started to sniffle and sneeze when she turned seven, I knew that I didn't want to stop my child from experiencing a fulfilling childhood. After a meeting with an allergist and a blood test, I found out that my daughter was allergic to pollen during the spring, summer, and fall months. I decided to allow my daughter to start shot therapy. While my daughter built up an immunity to the allergens, I decided to lessen symptoms by using natural health techniques. I found a variety of options online. Unfortunately, I had to weed through a great deal of information to find out what worked and what didn't. Let my research and trials guide you, so you can find out what really works.
