摘要：A system for controlling noise for a sound receiving device directs noise towards the sound-receiving back side of a bi-directional microphone and directs the user's voice away from the back side. The bi-directional microphone is electrically connected to plug adapted for mating with an external microphone input jack of the sound receiving device. A resistor is connected in series with the bi-directional microphone and operates to attenuate the detected sound signal of the bi-directional microphone in order to overcome signal enhancement expedients of the sound receiving device, such as compression and clipping due to for example automatic gain control.
