HOW DO I HANDLE FEEDBACK SOUNDS FROM MY HEARING AIDS?

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 devices emit three types of feedback sounds.

●Acoustic feedback – When the amplified sound from the hearing aid speaker is picked up again by the microphone, it makes a louder, harsher sound that is unsettling to the user.

●Mechanical feedback – Even though it may be really hard to deal with it, it is easy to fix. It is caused by the vibrations that occur when the hearing aid speaker comes into contact with the device housing.

●Electronic feedback- This happens when there is a problem with the circuitry of the hearing aid.

 

How do I handle feedback sounds?

Don’t hit the device hard, for example on the desktop, thinking it will stop the noise. No, it won’t. Instead, it may damage the internal parts of your headset.

Never try to fix it yourself just because you have mechanical knowledge, unless you repair hearing aids for a living. You may not be able to diagnose and fix the problem. Take it to your audiologist without a second thought!

Don’t throw away your device out of frustration. Your hearing aid machine only needs a few minor adjustments.

Switch to a digital hearing aid. You have many reasons to do so. Not only will you have an enhanced hearing experience, but modern digital hearing aid devices also feature feedback suppression. However, if you are already a digital hearing aid user and you can still hear these disturbing sounds, then you may have some problems with your device.

Check the fit of the device. Push the device as deep into the ear canal as possible to create a tighter seal. Improperly fitted hearing aids may allow amplified sound waves to escape and return to the microphone. This can cause sounds to be re-amplified while they appear to be distorted. Ask your audiologist to fit the hearing aid properly and make sure the machine has the correct size ear tips that fit and don’t just lie loosely in the ear canal.

Check for earwax buildup. If sounds hit hard lumps of earwax, they may bounce out of the ear and re-amplify, creating an annoying sound.

It is recommended that a professional audiologist be consulted to analyze the problem that is causing the feedback sound. If there is a problem with the device, he or she will make fine adjustments or adjustments. He or she may also recommend that you use a digital hearing aid with feedback suppression

ADVANCES IN HEARING AID TECHNOLOGY: IMPROVING LIVES FOR THE HEARING IMPAIRED

图片
Hearing aids are becoming increasingly popular as a solution for those with hearing loss. With the aging population, the demand for hearing aids is expected to increase in the coming years. Advances in technology have made hearing aids more powerful, smaller, and easier to use. There are two main types of hearing aids: behind-the-ear ( BTE ) and in-the-ear (ITE). BTE hearing aids are worn behind the ear and have a small tube that connects to an earpiece that sits inside the ear canal. ITE hearing aids are worn inside the ear canal and are custom-made to fit the individual’s ear. Recent developments in hearing aid technology have led to the development of “smart” hearing aids. These devices are capable of connecting to smartphones and other devices, allowing the user to control the hearing aid through an app. They can also adjust to different listening environments, such as a noisy restaurant or quiet office. Another recent development in hearing aid technology is the use of artificial

hearing Loss   is a widespread issue that can greatly affect communication and overall well-being. It is essential to take proactive measures to protect our   hearing   and maintain good   auditory health . This article provides valuable tips and strategies for safeguarding our ears from noise-induced hearing loss. Limit Exposure to Loud Noises: One of the most effective ways to prevent hearing loss is by minimizing exposure to loud sounds. Encourage individuals to avoid or reduce their time in noisy environments, such as attending excessively loud concerts or sporting events. In situations where exposure to loud noises is unavoidable, it is crucial to use  earplugs  or earmuffs to reduce the intensity of sound and protect the delicate structures of the inner ear. Utilize Volume-Limiting Devices: With the prevalence of personal audio devices like smartphones and MP3 players, it is important to promote the use of devices with volume-limiting features. These features restrict the maximum

Binaural hearing brings you a better hearing experience

hearing   impairment in one ear for an extended period may lead to a gradual increase in the   hearing Loss   of the weaker ear and can impede the development of the hearing pathway. In a similar vein, hearing deprivation in one ear may compromise the ability to locate sounds accurately. When an individual cannot judge the direction of a sound source, it can lead to potentially hazardous situations. Additionally, hearing difficulties are often exacerbated in noisy environments, and individuals may struggle to discern critical information. For instance, even in quiet settings, it may be possible to miss essential sound cues. Asymmetric hearing loss during childhood can lead to developmental barriers to language acquisition, intellectual hurdles, and difficulties in communication, highlighting the importance of early intervention. Binaural hearing offers several benefits, such as eliminating hearing deprivation in the weaker ear. For children, early intervention is crucial for developing
