Claim:
1. An orientation detector comprising: a first microphone transducer having a first position, a second microphone transducer having a second position, and a reference microphone transducer spaced from the first microphone transducer and the second microphone transducer, wherein each microphone transducer is configured to emit a respective signal in correspondence with an acoustic signal received by the respective microphone transducer; a separation unit; and an orientation processor configured to determine an orientation of the first microphone transducer, the second microphone transducer, or both, relative to a source of the acoustic signal based on a comparison of a first computed signal-separation associated with the first microphone transducer and the reference microphone transducer to a second computed signal-separation associated with the second microphone transducer and the reference microphone transducer; wherein the separation unit generates the first computed signal-separation and the second computed signal-separation.
