Abstract:
1. A method of matching an output of an auxiliary signal transducer with a reference signal transducer where the auxiliary signal transducer and reference signal transducer receive audio signals from a common signal source along different respective signal paths with different acoustical characteristics wherein the signal path of the reference signal transducer is line-of-sight and the signal path of the auxiliary signal transducer is not line-of-sight, such method comprising the steps of: determining a signal amplitude output value provided by the auxiliary and by the reference transducers through the line-of-sight signal path of the reference transducer and the not line-of-sight signal path of the auxiliary transducer within each of a plurality of different frequency ranges in response to the audio signal received along the respective signal paths; and adjusting the signal amplitude output value of the auxiliary transducer within at least some of the plurality of different frequency ranges based upon the respective signal amplitude output value of the reference transducer.
