1. A microphone transmitter comprising:
a portable housing;
a microcontroller;
a microphone receiving sound arriving via a first port and a second port located in the portable housing and generating a microphone input signal, the microcontroller providing a noise-control signal based on whether noise or voice is arriving at the microphone ports, and generating a noise-attenuated signal output in the absence of voice;
a transmitter circuit operable for transmitting the noise-attenuated signal;
an accelerometer circuit configured to generate an orientation signal based on a sensed orientation of the portable housing,
a power source configured to power the microcontroller, the microphone, the transmitter circuit, and the accelerometer circuit,
wherein the power source, the microcontroller, the microphone, the transmitter circuit, the accelerometer circuit are located within the portable housing, and
wherein the microcontroller receives the orientation signal and operates in a high gain mode when the portable housing is in a horizontal position or in a low gain mode when the portable housing is in a vertical position.
