Hearing Loss Specialists Assess Hearing Ability And Range With Audiograms
When someone hears the term 20/20 vision, it is generally understood that reference is being made to the presence of normal or sharp vision – in other words, someone had an eye test and does not need glasses. From a more technical standpoint, 20/20 vision means that the person can clearly see at 20 feet what they should normally be able to see at that distance.
Unfortunately, when the subject turns to measuring hearing loss or clarity, the general public might not be as well informed, or as diligent, as they are with assessing their sight or vision. People will make casual references to seeing an eye specialist or going for an eye exam, but might often express concern or uncertainty about having a hearing test.
Perhaps this trepidation is in reaction to a suggestion or recommendation that they need to schedule an audiogram? After all, this is a somewhat technical term that might not be readily understood (they usually put drops in your eyes for an eye test but what do they give you for an audiogram?).
In actual fact, an audiogram is neither a procedure nor a test – it simply refers to the printed record or graphical representation of hearing test results. It is this printout or charting that allows hearing loss specialists to assess:
- How well a person hears different types of sounds
- Whether there has been any hearing loss, and
- The extent of that hearing loss (range of frequency)
Without getting too technical, the frequency ranges of normal hearing and hearing loss are expressed in decibel levels (db HL), and specialists will use audiograms to confirm the following results:
- Normal hearing
- Mild hearing loss – soft sounds (low frequencies) are not heard
- Moderate hearing loss – understanding speech (50 db HL) is difficult
- Severe hearing loss – conversations must be conducted loudly
- Profound hearing loss – a hearing aid is needed to communicate
Based on the above progression of hearing impairment, and an acceleration in frustration and lack of enjoyment of everyday activities per level, any suspicion of hearing impairment should be addressed with an appropriate urgency. This is done by scheduling a hearing test with a Toronto hearing clinic such as Bravo Hearing Centre.
A Hearing Test Centre Can Confirm Your Hearing Loss And Course Of Treatment
Hearing loss can occur when sounds are not properly conducted through the ear or when sound signals are not fully transmitted from the ear to the brain. There can be several causes for such situations, including:
- Issues relating to anatomical structure
- Hereditary/congenital factors
- Trauma or damage to the ear
- Health/medical reasons
Treatment should be sought as soon as possible if any impairment is suspected. This would begin with a visit to a hearing test centre, where one of their specialists can perform a free hearing test. The results of that test, shown on an audiogram, will determine the next steps, and specifically whether a hearing aid will be required.
If you suspect that you or a family member may have any degree of impairment, call the specialists at Bravo Hearing Centre today> at 416-207-9711
