A useful visual aid to understanding hearing tests is a chart called an an audiogram. According to Healthy Hearing, an audiogram is a visual display of which sounds you were able to hear during your hearing test. It can assist you with determining how severe your hearing loss is. You may be provided with an audiogram after your hearing test, but if you weren't, it's easy to convert written data to a chart.

Moderately Easy

### Things you need

• Pencil
• Ruler
• Graph paper
• Coloured pencils

## Instructions

1. 1

Draw an "L" shape on graph paper. Make the bottom (horizontal) leg 14 blocks wide and the vertical leg 13 blocks tall.

2. 2

Label your horizontal axis "Frequency in Hertz (Hz)." Label your vertical axis "Hearing Level in Decibels (dB)."

3. 3

Starting at the top left, write the following numbers in descending order on the vertical axis. Place one number at every line on the graph paper: -10, 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 120.

4. 4

Starting at the bottom left, write the following numbers from left to right on the horizontal axis. Write one number every two lines: 0, 125, 250, 500, 1000, 2000, 4000, 8000.

5. 5

Color the rows of your graph as follows. Bottom three rows: dark pink; label this area "Profound Hearing Loss." Next two rows (going up): light pink; label this area "Severe Hearing Loss." Next three rows: yellow; label this area "Moderate Hearing Loss." Next two rows: light blue; label this area "Mild Hearing Loss." Next three rows: leave white; label this area "Normal Hearing."

6. 6

Chart the readings for your left ear. Your data will have a frequency listed with a corresponding decibel value. For example, for a frequency 250 Hz, you may have 20 decibels listed. Mark this point on your graph (where the lines for 250 Hz and 20 decibels meet) with a small "x". Repeat for all readings on your left ear.

8. 8

When you are done plotting your scores, join the "o" marks with lines, and join the "x" marks with lines.

#### Tips and warnings

• Make sure you know what the "x's" and "o'"s represent (left or right ear) by jotting down on the side of the graph which is which.
