I am writing about the hearing test in Canberra. I mean Helen King, she’s a Canberra Audiometrist. An Accredited Practitioner and Qualified Audiometrist and also a member of Aid Audiometrist Society of Australia. Perhaps, you are having a hearing problem, I want to let you know that you are unique and deserve the best treatment and this is exactly what Helen will give you at the appropriate time.

There is an offer of a 60-day return option on your hearing aids and they also offered different payment options. Nevertheless, I will work you through the rudiment of hearing loss.

Hearing Loss and Audiometry

Hearing loss accompanies age however it can affect anybody. Studies show that at any rate 25% of people over 50 years of age experience hearing loss, and 50 percent of people over 80 years of age experience it as well. However, an approach to test for hearing loss is using audiometry.

An audiometry test helps your hearing functions. It tests both the intensity and the tone of sounds, balance issues, and different issues identified with the function of the inner ear. A doctor who specializes in diagnosing and treating hearing loss is called an audiologist.

The unit of measure for sound intensity is the decibel (dB). A healthy human ear can hear calm sounds like whispers. These are around 20 dB. A loud sound, for example, a jet engine is somewhere in the range of 140 and 180 dB. The tone of a sound is measured in cycles each second. The unit of measure for tone is Hertz (Hz). Low bass tones measure around 50 Hz. Humans can hear tones between 20-20,000 Hz. Human speech generally falls in the 500-3,000 Hz range.

Reason for Audiometry

An audiometry test is performed to determine how well you can hear. This might be done as part of a routine screening or in light of an observable loss of hearing. The common causes of hearing loss include:

  • Birth defects
  • Injury to the ear
  • Inner ear illnesses, like Ménière’s sickness or an immune system infection that influence the inner ear
  • Chronic ear infections
  • Inherited conditions, like otosclerosis, which happens when a strange development of bone keeps structures inside the ear from functioning properly
  • Customary openness to loud noises
  • Burst eardrum
  • Damage to the ear or openness to loud sounds for a significant stretch can cause hearing loss. Sounds louder than 85 dB, for example, you hear at a stage performance, can cause hearing loss after a couple of hours. It’s acceptable to utilize hearing protection, for example, foam earplugs, in case you’re presented to loud music or industrial noise consistently.
  • Sensorineural hearing loss happens when hair cells in the cochlea aren’t working properly. The cochlea is the part of the ear that makes an interpretation of sound vibrations into nerve motivations to be shipped off the brain. Sensorineural hearing loss can likewise happen because of damage to the nerve that conveys sound data to the brain or damage to part of the brain that measures this data. This sort of hearing loss is generally permanent. It tends to be gentle, moderate, or serious.

How Audiometry Works

There are a couple of tests engaged with audiometry. A pure tone test measures the quietest sound you can hear at different pitches. It includes utilizing an audiometer, which is a machine that plays sounds by means of earphones. Your audiologist or an assistant will play an assortment of sounds, like tones and speech, at different spans into each ear in turn, to determine your range of hearing. The audiologist will give you instructions for each sound. In all likelihood, they’ll request that you lift your hand when a sound gets audible.

Another hearing test permits your audiologist to evaluate your ability to distinguish speech from background noise. A sound example will be played for you and you’ll be approached to rehash the words you hear. Word acknowledgment can be useful in diagnosing hearing loss. A tuning fork might be used to determine how well you hear vibrations through your ears. Your audiologist will set this metal gadget against the bone behind your ear, the mastoid, or utilize a bone oscillator to determine how well vibrations go through the issue that remains to be worked out by the inner ear. A bone oscillator is a mechanical gadget that communicates vibrations like a tuning fork.
