How to Read a Costco Hearing Test

Understanding Your Hearing Examination

The style to a hearing aid fitting often begins with a feeling that your hearing is not equally it should be or that your hearing has worsened. This feeling may originate from situations where you lot accept to ask for sentences to be repeated or when other people mutter that the television is besides loud while you regard it as comfortable. Making a serious mistake, family pressure, or safety concerns are also reasons people often cite for seeking a hearing solution.

If you doubtable a hearing loss contact a hearing care professional as soon every bit possible.

A hearing care professional determines with the help of a hearing test whether or not a hearing loss is present. If no hearing loss is nowadays, you won't demand any further aid. In the instance where a hearing loss is present, the kind and degree of your hearing loss is determined individually for each ear and entered in an audiogram.

How to Read Your Hearing Test

Hearing is graphed on an audiogram, a graph of the softest sounds you can hear. The graph is laid out like a piano keyboard, with low to loftier frequencies (low to loftier pitches) going from left to right, ... and the graph is laid out from soft sounds on the top to loud sounds on the bottom.

And then once your graph is filled in (ten represents the left ear, o the correct), ... it shows your hearing sensitivity for different frequencies at different intensities (at different pitches and different volumes).

Hearing is Non measured in percentages. Instead, it is measured in an arbitrary unit of loudness chosen the DECIBEL. The decibel (dB, or dB HL) is a logrithmic calibration. Physically, every 6 dB increment represents a doubling of sound pressure level. Perceptually, every ten dB increase sounds twice every bit loud.

Every increase of 10 decibels (10 dB) sounds twice equally loud. 20 dB sounds twice equally loud as x dB... 40 dB sounds twice equally loud as thirty dB and viii times as loud as x dB (10 to 20 to 30 to 40 = ii x 2 x two = viii).

Normal hearing ranges from 0 to 20 dB in all frequencies.

From here on, the assumption is that you have a sensorineural hearing loss (that y'all have nerve damage to the inner ear). Nerve damage, unless sudden, is permanent.

For conductive hearing losses, encounter your otolaryngologist (your ENT physician). For sudden hearing losses, see your otolaryngologist inside a day. If yous cannot, become an immediate medical evaluation elsewhere.(side by side)

If yous have a standard audiogram, highlight the twenty dB line that crosses the graph from left to correct.

If all of the X's (for the left ear) and all of the 0's (for the right ear) fall above the line y'all simply drew, you have normal hearing. If anything is below that 20 dB line, you take a hearing loss.

Your hearing loss is classified according to how far downwardly the graph the marks become, and in what freqencies the loss occurs. (The next folio requires about 55 seconds to load at xiv.4kbaud. Delight open up your browser to at least equally wide equally the row of glass beads below this paragraph.) Here are some mutual hearing losses...

In a standard audiogram, the numbers across the tiptop of the graph get-go at 250 Hertz ("Hz," or cycles per 2d) and proceed to 8k Hz (8000 cycles per 2d), with the following one octave intervals: 250 / 500 / 1k / 2k / 4k / 8k. Every octave -- every interval across the pinnacle -- forms a square with every 20 decibel (20 "dB") modify going down.

Some other common variations include putting the left and right ears on different graphs, and using a dissimilar interval for the frequencies across the elevation. The most mutual variant uses the post-obit frequency intervals: 250 / 500 / 1k / 2k / 3k / 4k / 6k / 8k. If you have this kind of graph, the right half of the pattern of your hearing examination will be stetched out, as shown below, on the right:
