System and method of audio testing of acoustic devices

A method of testing audio performance, the method comprising:

• providing a two-way mobile voice-enabled communications device, the device comprising a microprocessor, a microphone connected to the microprocessor, a speaker connected to the microprocessor, an auxiliary input/output device connected to the microprocessor, a memory connected to the microprocessor, and a software module stored in the memory which configures the microprocessor to route signals from the auxiliary input/output device to the speaker;
• producing a speaker electric audio test signal on an audio generator external to the two-way mobile voice-enabled communications device;
• providing the speaker electric audio test signal as input to the auxiliary input/output device from the audio generator;
• directly routing the speaker electric audio test signal using the microprocessor of the mobile voice-enabled communications device from the auxiliary input/output device to the speaker;
• outputting from the speaker a speaker acoustic audio output signal corresponding to the speaker test electric audio signal;
• providing the speaker acoustic audio output signal from the speaker as an input to an external microphone;
• outputting a speaker electric audio output signal corresponding to the speaker acoustic audio output signal from the external microphone to an external test system;
• and
• analyzing the speaker electric audio output signal output from the external microphone on the external test system.
