## How do I interpret my audiogram?

Looking at the audiogram graph, you will see two axes: The horizontal axis (x-axis) represents frequency (pitch) from lowest to highest. The lowest frequency tested is usually 250 Hertz (Hz), and the highest is usually 8000 Hz.

## How do you calculate hearing loss from an audiogram?

Take the thresholds for four frequencies (500,1000,2000,3000) for each ear and average them. Increase by 1.5% for each dB above 25dB for each ear. Multiply the better ear by 5 (to weight it more heavily). Add that number with the worse ear and divide by 6 to get your hearing handicap.

## What does the symbol on an audiogram represent?

An Audiogram is the universal way to represent someone’s hearing in the form of letters and symbols. An O represents the right ear while an X represents the left ear. These Xs and Os represent air conduction thresholds.

## What does an audiometry test measure?

An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear.

## What does AC masked mean on an audiogram?

Masking means that one puts in some “noise” in the opposite ear while testing an ear. The reason to do this is to prevent sound from the side being tested from going over to the good side This is called the “cross-over problem”.

## What does UCL mean on an audiogram?

Uncomfortable Loudness Level
Uncomfortable Loudness Level (UCL) is defined as the hearing level at which a stimuli becomes uncomfortable for the listener.

## What are the 2 axes in an audiogram?

An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer. The Y axis represents intensity measured in decibels and the X axis represents frequency measured in hertz.

## What are the 4 levels of deafness?

The Four Levels of Hearing Loss â€“ Where Do You Fit?
• Mild Hearing Loss.
• Moderate Hearing Loss.
• Severe Hearing Loss.
• Profound Hearing Loss.

## What is a normal UCL?

Average UCL is similar for people with normal hearing or sensorineural hearing loss with thresholds below about 50 dBHL, with a gradual increase in UCL as hearing threshold increases (Kamm et al., 1978).

## What should the SRT number be on hearing test?

An SRT is considered to be normal if it falls in the range of -10 to 25dB HL (Hearing Level). Even though an individual might obtain a value within this normal range, this does not always mean that he has completely normal hearing acuity.

## What does pure-tone average mean?

Pure-tone average (PTA) is the average of hearing sensitivity at 500, 1000, and 2000. This average should approximate the speech reception threshold (SRT), within 5 dB, and the speech detection threshold (SDT), within 6â€“8 dB.

## What is uncomfortable loudness level?

Audiologists often use Uncomfortable Loudness Levels (ULLs) to identify the sound levels that are perceived as â€śtoo loudâ€ť. ULLs of less than 80 dB HL can be considered as abnormally low. In cases of severe hyperacusis the ULLs can be as low as 30 dB HL.

## What does dB HL stand for?

Decibels in hearing level, or dB HL, is com- monly used in audiology because it refers to the decibel level on the audiometer. The reference level for dB HL is â€ś0,â€ť which is related to the average threshold in decibels sound pressure level (dB SPL) for the average, normal-hearing listener. In Fig.

## How is PTA test done?

Pure tone audiometry is a hearing test using an audiometer that sends tones into the client’s ear and vibrations through the bone. It measures the frequencies at which the client is able to hear 50% or more of the tones.

## What does a 40 dB hearing loss mean?

Mild Hearing Loss: Between 26 and 40 Decibels. Moderate Hearing Loss: Between 41 and 55 Decibels. Moderate to Severe Hearing Loss: Between 56 and 70 Decibels. Severe Hearing Loss: Between 71 and 90 Decibels. Profound Hearing Loss: Between 91 and 100 Decibels.

## Does 50 dB hearing loss mean?

If you can only hear sounds when they are at 30 dB, you have a mild hearing loss. You have a moderate hearing loss if sounds are closer to 50 dB before you hear them. To find out how loud common sounds are, visit the noise page.

## What is a difference between dB SPL and dB HL?

Decibel (dB) Decibel refers to the loudness of sounds. … dB SPL vs. dB HL Loudness of sound is typically measured in sound pressure level (dB SPL). The output of hearing aids and assistive listening devices is displayed in dB SPL; however, auditory thresholds (on an audiogram) are measured in hearing level (dB HL).

## Is 16000 Hz a good hearing?

People under 50 should be able to hear the 12,000hz and people under 40, the 15,000hz. Under 30s should hear the 16,000hz, and the 17,000hz is receivable for those under 24.

## Is 18000 Hz a good hearing?

The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there.
