3.7.10 Single Frequency
Single Frequency tests the hearing aid at a single selected frequency using a given stimulus. This allows you
to get an impression of the hearing aid at specific important frequencies.
If selecting a pure tone or warble tone stimulus a bar representing the fundamental frequency together with
harmonics will appear on the graph. If selecting a noise stimulus a FFT spectrum shows on screen.
The Single Frequency measure is useful in order to see how much the hearing aid distorts the signal.
