Learning Hub

The Canadian Hard of Hearing Association (CHHA), Sudbury Branch, is dedicated to educating the general public as well as those who have hearing loss about its issues and preventions.

About FM Systems

An FM (Frequency Modulation) System utilizes radio waves and is a wireless system and is useful when the speaker is more than a few feet away (up to 150 feet) The microphone and receivers are battery operated and generally use rechargeable batteries. Since it uses FM radio waves it will also transmit sound through objects and walls.

About Hearing Aids

Hearing aids are an important tool in effectively managing your hearing loss.  Today there are a considerable number of choices in the styles and features available in hearing aids.  The benefits of well fitted hearing aids can dramatically improve your quality of life. 

About Hearing Loops

A hearing loop or audio frequency induction loop system, is wireless technology that sends an electromagnetic signal directly to an individual’s hearing aid like they have a little speaker in their ear.

About Hearing Loss

Hearing loss has become quite prevalent. In the past, an accepted statistic was ten percent of the population as being estimated to have some level of hearing loss. Today, that number has increased.

About Infrared Systems

Infrared systems are another wireless system that uses light waves to transmit sound. They are available for home/personal use and in larger area situations and provide a high quality sound fidelity for music and speech, making them excellent for watching TV or listening to music.

About The Cochlear Implant

Learning to hear and listen with a cochlear implant can be an exciting journey.  It can also be fraught with frustration for many.  CHHA-Sudbury Branch provides resources and peer mentoring for recipients of a cochlear implant and those considering a cochlear implant.

About The Ear

The ear consists of three major compartments, the outer ear, the middle ear and the inner ear. Sound vibrations are collected by the outer ear and travel down the ear canal to the eardrum (also know as the tympanic membrane). When the sound waves reach the eardrum it causes it to vibrate in rhythm with the sound energy it is absorbing.

About The T-Coil

Many assistive listening devices work best in conjunction with a T-Coil. a T-coil, or telecoil, is a small copper coil in a hearing aid that functions as a wireless antenna that links to a sound system or PA system, delivering customized sound to the hearing aid wearer. It is an option on most hearing aids and is generally in all cochlear implant processors.

About Tinnitus

Tinnitus is a medical term and is defined as the perception of sound when there is no external sound present. Tinnitus is frequently referred to as ‘ringing in the ears’, but this is misleading as tinnitus can also include numerous other sounds such as buzzing, hissing, roaring, whistling, pure tones, etc.
