First Claim
1. A hearing assistance device, comprising:
- a processor;
a radio frequency transceiver connected to the processor;
an acoustic input;
a magnetic input; and
a detection circuit connected to the processor, the detection circuit including multiple band pass filters configured for uplink and downlink frequencies associated with cellular communications, and wherein the detection circuit is adapted to monitor a radio frequency signal to detect a cellular telephone in proximity to the hearing assistance device based on the monitored signal,wherein the processor is configured to switch between the acoustic input and the magnetic input when the cellular telephone is detected in proximity to the hearing assistance device using the detection circuit.

Abstract
The present subject matter relates generally to methods and apparatus for detecting cellular telephones using hearing assistance devices. In an embodiment, a hearing assistance device includes a processor and a radio frequency transceiver connected to the processor. A detection circuit is connected to the processor, the detection circuit including a band pass filter and where the detection circuit is adapted to monitor a radio frequency signal to detect a cellular telephone in proximity to the hearing assistance device based on the monitored signal. The hearing assistance device includes an acoustic input, a magnetic input, and a switch for selecting between the acoustic input and the magnetic input. The processor is adapted to actuate the switch from the acoustic input to the magnetic input when a cellular telephone is detected in proximity to the hearing assistance device.
