Abstract
A method includes generating, by a noise generator of an apparatus, a noise signal stream. The method includes outputting, via an audio output device of the apparatus, the noise signal stream towards an audio input device of a personal communication device. The noise signal stream travels from the audio output device towards the audio input device via an audio-sealing pathway. The method includes receiving a recorded representation of the noise signal stream from the personal communication device. The recorded representation of the noise signal stream is a function of a transformation of the noise signal stream, by the audio-sealing pathway, and characterizes an audio transfer function of the audio-sealing pathway. The method includes determining, by the controller of the apparatus, whether or not the audio-sealing pathway satisfies an operational criterion based on the recorded representation of the noise signal stream and a reference transfer function associated with the audio-sealing pathway.
