Method and system for conducting hearing aid compatibility testing of a mobile communication device
View Patent ↗Embodiments relate to a system for conducting hearing aid compatibility testing of a mobile communication device. The system comprises: a simulated hand for supporting the mobile communication device during the testing; a probe; and a processor. The processor is configured to cause the probe to be positioned in a sequence of positions in proximity to the mobile communication device relative to an audio output component of the mobile communication device during the testing and to determine a field strength of a field radiated by the mobile communication device at the sequence of positions based on an output of the probe at each position.
