Melody A3 Fit Range Chart

Note: ALL of your test points from your hearing test must fit inside the blue area for this hearing aid model to help you. If any test points fall outside the blue area, we cannot help you. This is our strongest hearing aid model

To use this chart, you will need a copy of your hearing test (audiogram). If you do not have an audiogram, you will have to go to an audiologist to be tested as most family physicians do not have the test equipment to test your hearing.

Each test point on your chart denotes the intersection of a frequency at which you were tested (the frequencies are marked as hertz rates, usually 125 - 8000Hz, along the top of the graph), and the loudness that the tester had to turn up the sound before you heard it (marked as decibels, usually 0 - 120dB, along the left hand side of the graph). Your left ear test points are marked in X's and connected by a line, and you right ear test points are marked in 0's, also connected by a line.

If, instead of a chart, you just have two sets of numbers, the idea is the same: take each test point of hertz rate and associated decibel and plot it on the fit range chart on the left. 

Hertz Rate 250 500 1000 2000 4000 6000 8000
Right Ear Decibels 50 55 60 65 75 80 95
Left Ear Decibels 50 55 60 75 85 90 95

If all the test points fall within the shaded area of the chart, then this hearing aid has sufficient amplification to rectify some or most of your hearing loss.
