Hearing Aids
About nine in ten patients with hearing loss can be helped by hearing aids. Today’s digital devices are smaller and more powerful than ever, and include many state-of-the-art features designed to improve comfort, convenience and clarity. They are available in a variety of sizes and styles, so finding one that appeals to your lifestyle needs and cosmetic preferences should be easy.
Choosing a Hearing Aid
If you are experiencing hearing loss, odds are good that you’ll benefit from a hearing aid. But choosing the right one is no simple task. Today’s hearing aids are smaller and more feature-packed than their predecessors, offering an array of options.
Narrowing the choices down can be tough, but there are a few important things you should take into consideration before choosing a hearing aid.
What Are Your Hearing Needs?
First, you’ll need to have an audiologist assess your hearing loss. Severity is measured in degrees, based upon your hearing loss range in decibels. It ranges from normal (-10 to 15 dB) to profound (91+ dB), with a total of seven different degrees.
Equally important is the frequency of your hearing loss. Conductive hearing loss resulting from damage to the outer or middle ear affects low frequency sounds, while sensorineural hearing loss, in which damage occurs to the inner ear, results in a loss of high frequency sounds.
You’ll need to choose a hearing aid that targets the frequencies you have trouble comprehending.
What Are Your Lifestyle Needs?
Functionality is an important consideration. With so many available features, you’ll need to decide which ones matter most to you. Popular features include:
- Directional microphones
- Feedback suppression
- Amplifiers
- Digital noise reduction
- Wax guards
- Automatic volume control
- Bluetooth® connectivity
Extra features cost money, so speak with your audiologist to get an idea about the pros and cons of these features.
You’ll also have to take into account your lifestyle needs. Whether you enjoy quiet, intimate gatherings with a few close friends or an active outdoors lifestyle that includes a lot of background noise, there is a hearing aid designed specifically for your activity level.
What Is Your Cosmetic Preference?
Cosmetic preference is a key factor in choosing a hearing aid. Since you’ll be wearing it every day, it’s got to not only feel good but appeal to your confidence.
Hearing aids are available in a variety of sizes and styles, some visible while others are implanted deep within the ear canal, rendering them virtually undetectable. Many are custom-molded to fit each individual’s ears.
What Is Your Budget?
Finally, there is cost. Price will be a factor, but be sure to consider your specific hearing needs when making this decision.
Investing in a cheap hearing aid that is ineffective is a waste of money; conversely, you don’t want to overspend on features that won’t benefit you. Your audiologist can offer suggestions that will point you in the right direction.
Hearing Aid Technologies
Hearing aid technology has improved drastically over the past couple of decades. Early devices relied on vacuum tubes and bulky batteries, but today’s instruments take advantage of digital signal processing, microchips and computerization. Keeping track of the latest technological features can be challenging, but we’ll cover a few of the more popular options here.
Analog technology still exists, but fewer and fewer manufacturers offer these devices, and many have phased them out entirely. Analog units employ a particular frequency based on your audiogram and all sounds are amplified in the same manner, whether speech or background noise. Some analog hearing aids can be programmed for different listening environments.
Digital programmable hearing aids use digitized sound processing to convert sound waves into digital signals. A computer chip determines whether the signals are speech or noise and converts them into clear, amplified signals. Advantages in digital processing are significant: it offers improved programming ability, a more precise fit and a number of features designed to improve or enhance functionality, including:
- Gain processing reduces background sounds and microphone noise to offer a clearer sound for the listener, with less clinical adjustment needed.
- Digital feedback reduction (DFR) relies on cancellation systems to eliminate or reduce feedback.
- Digital noise reduction (DNR) reduces background noises for improved speech recognition.
- Directional microphones utilize dual microphones, focusing one on the sound source while the other decreases background noise, to enable the user to better determine directionality.
- Wireless connectivity with Bluetooth® devices provides great flexibility.
While the choices may seem overwhelming, working closely with your audiologist at the Sacred Heart University Audiology Clinic can help you figure out which technology and features are perfect for your needs.
