An electronic hearing protector, comprising: a first ear cup assembly comprising a first front exterior microphone that provides a first front microphone signal and a first rear exterior microphone that provides a first rear microphone signal; a second ear cup assembly that includes a second front exterior microphone that provides a second front microphone signal and a second rear exterior microphone that provides a second rear microphone signal; a processor that receives the first front microphone signal and first rear microphone signal, and provides a first front channel signal by delaying the first rear microphone signal by a time equal to a propagation time between the first front exterior microphone and the first rear exterior microphone and by subtracting the delayed first rear microphone signal from the first front microphone signal and provides a first rear channel signal by delaying the first front microphone signal by a time equal to a propagation time between the first front exterior microphone and the first rear exterior microphone and by subtracting the delayed first front microphone signal from the first rear microphone signal; a first filter that receives the first rear channel signal and provides a low pass filtered signal; a second filter that receives the low pass filtered signal and provides a notch filtered signal; a summer that receives a first signal indicative of the first front channel signal and a second signal indicative of the notch filtered signal and provides a summed signal; a transducer within the first ear cup that provides an audio signal within the first ear cup indicative of the summed signal. a first ear cup assembly comprising a first front exterior microphone that provides a first front microphone signal and a first rear exterior microphone that provides a first rear microphone signal; a second ear cup assembly that includes a second front exterior microphone that provides a second front microphone signal and a second rear exterior microphone that provides a second rear microphone signal; a processor that receives the first front microphone signal and first rear microphone signal, and provides a first front channel signal by delaying the first rear microphone signal by a time equal to a propagation time between the first front exterior microphone and the first rear exterior microphone and by subtracting the delayed first rear microphone signal from the first front microphone signal and provides a first rear channel signal by delaying the first front microphone signal by a time equal to a propagation time between the first front exterior microphone and the first rear exterior microphone and by subtracting the delayed first front microphone signal from the first rear microphone signal; a first filter that receives the first rear channel signal and provides a low pass filtered signal; a second filter that receives the low pass filtered signal and provides a notch filtered signal; a summer that receives a first signal indicative of the first front channel signal and a second signal indicative of the notch filtered signal and provides a summed signal; a transducer within the first ear cup that provides an audio signal within the first ear cup indicative of the summed signal.
