What exactly is a hearing aid?

They are sound processors enclosed in a case that fit in or above and behind the ear. Hearing aids contain microphones and speakers that compress, alter and shape the sounds of an immediate environment and project the processed sound to the eardrum to enhance audibility and comprehension to one with damaged hearing. Essentially, hearing aids are a highly customized personal computer that is small enough to fit in your ear.

Hearing Aids Features

Hearing aid technology is rapidly evolving which means on-going support, upgrades and repair. Nearly every year there are improvements to speech processing which controls noise suppression in noisy environments, feedback cancellation which prevents whistling, and device design developments that offer smaller sizes and greater reliability.  

Hearing aid manufacturers provided advancements in nearly all of the following features:

  •  Tinnitus Reduction –(“Ringing in the ears”)
  •  Cross-Hearing- (amplifying and routing sound between instruments for those that have lost hearing in one ear)
  •  Device integration – the ability to route other audio sources to the hearing aid and to enhance patient control over what they want to hear
  •  Device learning
  •  Patient programming
  •  Waterproofing

Hearing Aid Systems

Hearing aids are capable devices all by themselves but, you can now have integration of streaming technology, speech and music that can be routed directly to the hearing aids from mobile phones and devices, television, radio and public address systems utilizing Bluetooth or loop systems in particular.

Hearing Aid Styles

ABC Hearing works with you to find the hearing aid that maximizes ease of use and comfort. Hearing aids come in two general families.  


Completely-In-The-Canal (CIC) CIC hearing instruments are not easily visible. The hearing device is housed in a tiny shell that fits deep into the ear canal with the faceplate at the canal opening.


In-The-Canal (ITC) larger than a CIC whose shell extends into the concha – the bowl shaped area beyond the ear canal opening. The canal portion of the shell does not need to sit as deep in the canal as the CIC.

In-The-Ear-100x100In-The-Ear (ITE) larger than a ITC whose shell fills beyond the concha- the bowl shaped area beyond the ear canal opening. The shell size accomodates greater power in the hearing aid circuitry for moderate to severe losses and for those that require the larger size for easier handling.

Behind-The-Ear-100x100Behind-The-Ear (BTE) hearing instruments are extremely flexible for all types of hearing loss.There are two styles both of which have evolved into much smaller physical sizes for all hearing loss needs.

Receiver-In-The-Aid ( RITA ) This is the traditional BTE where the speaker (receiver) is housed within a curved shell that sits behind each ear. The sound is delivered through a clear tube to a mold that has been customized to comfortably fit inside each ear.

Receiver-In-The-Ear-100x100Receiver-In-The-Ear ( RITE) For this BTE style , the speaker (receiver) is separate from the shell. The speaker typically is inserted into a custom earmold or stock earpiece and fits inside the ear canal where sound is direct from the speaker to the ear. Only a thin wire joins the speaker to the electronics housed in the shell which fits behind the ear.
