No matter how stylish or advanced your   hearing aids  are, you are bound to hear whirring sounds when you use them. While sometimes these sounds are normal, sometimes it indicates that something is wrong with your device. Although the quality of sound you experience in your hearing aid device may be very good, these whirring sounds (called feedback sounds) may affect your hearing experience in some way. There are many newer digital hearing aids available today that come with feedback reduction. When sound is returned to the microphone from the receiver, it creates a feedback sound and therefore re-amplifies, causing a whirring sound. It creates headache-inducing screeching or squealing sounds, and those sounds are annoying!   Causes of feedback sound ●Excessive accumulation of ear wax ●Poorly fitted or improperly installed hearing aid tubes ●Cracked or broken tubes ●Deformed sound disassembled microphone ●Excessive volume at certain frequencies   Types of Feedback Sounds Hearing aid d

Introduction of CIC hearing AIDS One of your primary concerns when you find yourself in need of hearing aids may be visibility to others; one study found that making hearing aids virtually invisible increased the likelihood of people purchasing them by 30-40%. If a less conspicuous option is what you find yourself gravitating toward, completely in the ear canal (CIC) hearing aids are the prudent and ideal choice. Just as the name implies,  CIC hearing aids  are located completely inside your ear canal, which makes them very small and discreet. They are invisible to passersby except when someone is looking directly into your ear. The CICs are custom made as they are made from a mold taken from your ear canal. That means you’ll feel comfy with them, and they won’t move around inside your ear. Here’s how they work Sound flows into your ear canal, where CIC hearing aids process and amplify it, then send it into your ear canal to your eardrum. They are slightly different from invisible-in-t

The position of the hearing aid microphone can have an important effect on its performance. In their study, Lybarger and Barron (1965) found that in   BTE hearing aids , those with the microphone at the top performed better than those with the microphone at the bottom. In addition, Berland and Nielson (1969) reported that among the three types of hearing aids, ITE, BTE and supra-aural, the gain was 7-10 dB higher in the 2000 and 5000 Hz frequency range compared to the other two types of hearing aids due to the advantage of the microphone position of the ITE hearing aid. This is mainly due to the action of the pinna and the position of the ITE microphone in the ear. The microphone setup of the ITE has a superior localization ability compared to the BTE, whether worn in one or both ears, in quiet or in noisy environments (Orton and Preves, 1979). Also, the former showed a 7% superiority in word recognition (Randolph et al., 1977). In addition, the high frequency response of microphones l

The RIC is an open fitting digital hearing aid that has gained worldwide popularity since its introduction at the turn of the century. The appeal of RIC hearing aids The  RIC hearing aid  is placed behind the ear in a body that contains the microphone, amplifier and processing chip, while the receiver (speaker) is placed in the ear canal via a thin wire connection. This design means that the size can be smaller than traditional behind-the-ear hearing aids and produces a more natural sound with less acoustic feedback (whistling). Ability to hear high frequency sounds The first symptom of hearing loss for most people with hearing loss is the absence of high frequency sounds (e.g. finding themselves unable to hear an electric bell, birds chirping in the park, etc.). RIC hearing aids excel at amplifying high frequency sounds, while still producing a natural sound effect. Therefore it is very suitable for people with early detection of hearing problems or mild to moderate hearing loss, but

What is a hearing aid? What types of hearing aids are there? Hearing aids  are amplification devices that help people with hearing loss to improve their hearing and improve their speech and communication skills. There are several types of hearing aids such as cassette, spectacle, behind-the-ear, in-the-ear and canal hearing aids, among which in-the-ear hearing aids are the most widely used. Completely in-canal hearing aid: It is the smallest hearing aid that is placed in the deep ear canal and is completely unnoticeable, which is called “hidden hearing aid”. When should I wear hearing aids? Both adults and infants should be fitted with hearing aids when their average hearing loss is ≥40dB, and their hearing cannot be improved by medication, surgery and other treatments, and they are diagnosed by doctors as having irreversible hearing loss.   Who is a good candidate for hearing aids? Anyone with deafness of any nature who wishes to improve their ability to communicate verbally can be a

Unlike hearing aids that use traditional disposable batteries, rechargeable hearing aids have built-in batteries that do not need to be removed periodically. Instead of removing the batteries yourself, you plug the hearing aid into a charging unit each night, in a similar way to how a smartphone is charged. Let’s look at the advantages of rechargeable hearing aids in detail.   Stable performance Rechargeable hearing aids are a good choice for people who live in colder areas where zinc-air batteries have difficulty working properly due to low temperatures. In dry and cold environments, the zinc-air battery consumes power too quickly, resulting in unstable hearing aid performance, intermittent sound or poor sound quality. In comparison, lithium batteries perform better in low temperatures.   Environmentally Safe The best choice for those who are passionate about environmental safety – lithium battery rechargeable hearing aids. Lithium battery rechargeable hearing aids avoid the fate of d

Q: Do RIC hearing aids have a blocked ear problem?   A: Plugging is a problem that occurs when the external ear canal is closed (usually when wearing custom hearing aids or plugged earmolds) and some hearing aid users tend to experience a plugging effect, which can cause discomfort. The most common symptoms are a feeling of stuffiness and loud speech.   RIC-type hearing aids  are unique in that they have open ear plugs that allow air to flow in and out of the ear, solving the annoying problem of blocked ears. Q: Are RIC hearing aids suitable for people who wear glasses?   A: Glasses wearers can be uncomfortable and unattractive when wearing an earbud because the earhook and the frame of the glasses are stacked together. Unlike conventional earbuds, RIC technology separates the receiver from the main body of the hearing aid, so a thin, hidden wire is used instead of an earhook, making it ideal for people who wear glasses.   Q: Are RIC hearing aids suitable for elderly users?   A: Compar
