The Test is done at many different frequency so to produce the graph of the audio path response.
The purpose of the Test is to compare the audio path gain of a system composed of an amplifier and loudspeaker but you can test also only a loudspeaker or earphone. The phone generate a list of tones(frequencies), the signal is acquired from the microphone and the relative power is calculated for each frequency. Please note that 0dB is an undetermined value so the measures are relative and not absolute values.
