The Hearken Philosophy

Hearken is committed to hearing life with passion. As such, we provide much more than just hearing aids, we provide hearing rehabilitation. Most people think that getting hearing aids will be like getting a new pair of glasses. Unfortunately, it is not that simple. You have probably heard of many people that have been unhappy with previous hearing aid purchases. Many of these unhappy hearing aid users were not provided the necessary rehabilitation to their hearing. Most people with hearing loss have had trouble hearing for years, and their auditory nerve has started to atrophy. Just like a muscle that is not used will get weaker, our ability to hear after years of hearing loss becomes weaker, and is in need of rehabilitation.

If proper aural rehabilitation is not provided, one of two things is likely to occur.

  • The hearing aid wearer will think the aids are too loud and end up keeping the hearing aids in a drawer at home instead of in their ears,
  • The hearing aid wearer will hear slightly better than they did without hearing aids, but still not as good as they could be hearing. At Hearken Hearing, we firmly believe in the value of aural rehabilitation, and we will work closely with you over the course of weeks, months, and years, to provide the proper amplification.

Dr. Pettit and his staff are extremely kind and helpful and make me feel very welcome. Dr. Pettit is always willing to spend whatever time is necessary to make any adjustments I need and to be sure I am completely satisfied with my hearing aids. I highly recommend the services at Hearken Hearing!!

Hearing Aids

Hearing aids are instruments that amplify sound and assist with speech recognition. They come in many shapes and sizes, and are customizable to meet specific hearing needs and preferences.

Generally speaking, all hearing aids contain the same components: receiver (microphone), amplifier, speaker, battery, and program/volume control. Hearing aids function in the same way your auditory process does. First, sound is picked up by the microphone. This sound is then amplified and fed to your ear by the speaker. The sound your ear receives is processed by a chip which uses algorithms to balance and clarify sound. The hearing aid is powered by a battery.

Hearing aids come with many different features, as well. Telecoils are an optional feature; these allow your hearing aid to connect to a hearing loop system, an assistive listening system that feeds amplified sound via electromagnetic waves directly to the hearing aid. Some hearing aids come with wireless features, such as Bluetooth, which allow you to connect to your smartphones and personal electronic devices. These also assist in the amplification of sound.

Hearing Aid Styles

Hearing aids are worn in several different styles in your ear.

receiver in canal hearing aids


Receiver-in-canal (RIC) hearing aids look like BTE hearing aids, but there are some minor differences. The plastic casing worn over the ear holds the microphone and amplifier, while the receiver rests in the canal. The receiver picks up sound through thin electric wire encased in plastic tubing, which is fitted in the ear canal. Like BTE hearing aids, RIC hearing aids offer ease of control and discreet design. They may also be inconvenient for glasses-wearers.

In the Ear (ITE)

In-the-ear (ITE) hearing aids are available in two styles. Full shell and half-shell ITE hearing aids are worn in the open face of the ear. They are made from a custom mold of the wearer’s ears. As such, they are more visible than BTE or RIC models. ITE hearing aids treat mild to profound hearing loss. While ITE hearing aids accommodate people who wear glasses, because of how they are worn, they may pose difficulty for people with dexterity issues. The program controls on the hearing aid and the battery door are generally smaller.

In the Canal (ITC) & Invisible in Canal (IIC)

In-the-canal (ITC) hearing aids are one type of ITE hearing aids. Customized to a mold of your ear canal, ITC hearing aids sit deep in your ear canal and are usually not visible. ITC hearing aids are available in completely-in-canal and invisible-in-canal styles. Because they are worn deep in the ear canal, they accommodate active lifestyles and offer discretion as they are usually not visible. ITC hearing aids treat hearing loss degrees from mild to severe. Due to their small size, removing them, changing batteries, and switching between programs may be difficult.

Behind the Ear (BTE)

Behind-the-ear (BTE) hearing aids are made of two main parts. The electronic components of the hearing aid are housed in a plastic casing, which sits on the back of your ear. The sounds received will be fed through a plastic tube that sits in your ear canal.

BTE hearing aids accommodate a wide range of degrees of hearing loss, from mild to profound. The way they are worn is preferred for their discretion, as they are often barely visible. BTE hearing aids are also very easy to control, which makes them preferable to people who experience dexterity issues, such as arthritis. Unfortunately, because of their positioning on the ear, they may be inconvenient for people who wear glasses.
