Abstract: A system and method for passively balancing electroacoustic transducers so that sounds other than the transducer's output can be detected. A transducer producing audio output based upon an input audio signal can operate in reverse to produce a signal in response to the impact of external sound upon the transducer from another source. This “reverse” or “microphone” signal represents the sound from the other source. Transducers are operated in monophonic mode, each in opposite polarity to the other thus canceling out and leaving only the microphone signal created by the transducers, i.e., a signal representing the external sound. The microphone signal can be amplified, and can be filtered and processed to identify and/or obtain various types of information about the sound received by the transducers.
