What is involved in a hearing test? Would I notice my hearing loss? What are some common signs of hearing loss? Will hearing aids restore my hearing to normal? Will my hearing aids help in the presence of background noise? Why do I need two hearing aids? How do I go about getting my hearing tested?
The Hearing Instrument Specialist will take a case history to discuss hearing challenges and medical history. An otoscope is used to examine the ear canal and ear drum. The Specialist will also measure the health of the middle ear by performing immittance and acoustic reflex tests. In a soundproof booth, via foam plugs or headphones, both pure-tones and speech sounds are presented. You are asked to indicate when a tone is audible and to repeat words when presented. A bone conductor is also used to assess the hearing of the inner ear. The results are transcribed onto an audiogram.
An audiogram is a graphic representation of the results of a hearing test. During a hearing test, sounds are presented at a variety of pitches or frequencies. The softest sound the individual can hear at each frequency is recorded on the graph. The Hearing Instrument Practitioner uses the results of the hearing test to establish if there is a hearing loss, the nature and degree of the hearing loss and hearing instrument options.
Not necessarily. Hearing loss often develops slowly and subtly. In fact, it is quite common that the signs of hearing loss are first detected by family and friends. Unfortunately, many people who suspect they have a hearing loss are reluctant to seek help. Untreated, hearing loss can have a negative impact socially, psychologically and cognitively. Having a hearing test as soon as a loss is suspected is really the best advice.
What are some common signs of hearing loss?
You
struggle to understand conversations in groups or in the presence of background
noise.
You
frequently misunderstand parts of conversation or need to ask people to repeat
them selves.
You
believe that “everybody mumbles” or “people don’t speak as clearly as they
used to.”
Friends
and family have complained that the level at which you listen to the television
or radio is too loud.
You
find you can’t hear as well if you can’t watch people's faces or if people try
to talk to you from another room.
You
become anxious, irritable, or exhausted from the effort to hear. Will hearing aids restore my hearing to normal?
The most common type of hearing
loss is sensorineural or ‘nerve deafness’.
Because the nerves required to transmit signals to the brain are damaged,
simply making sounds louder will not always make them perfectly clear. Hearing aids are designed to provide varying
amounts of volume for different frequencies and intensities. This allows the Hearing Instrument
Practitioner to program the hearing aid to amplify the sounds you are missing
without making sounds you already hear too loud. As a result, speech understanding is improved
and less listening effort is required. Understanding speech in background noise is one of the most common complaints for those with hearing loss. Advancements in hearing aid technology, directional microphones for example, are designed specifically to improve speech understanding in noise. The overall benefit will depend on a variety of factors such as degree of hearing loss, frequency of use and the style of hearing aid selected.
Two hearing aids are often recommended for
individuals that have binaural hearing loss, which means a hearing loss in both
ears. Our brain uses cues from both ears to determine which direction sounds
are coming from, allowing us to locate the source of the sound. Wearing only
one hearing aid comprises this ability and therefore, is not as effective as
wearing two. Providing stimulus to the brain from both ears allows for better
spatial awareness, fuller sound quality and improved speech understanding in
noisy environments. You can use our website’s Find Member feature to locate an AHIP member in your area.
