1. An apparatus, comprising:
a bone conduction microphone that obtains vibration signal data;
an air conduction microphone that obtains tonal signal data; and
a signal processor that processes the vibration signal data and the tonal signal data, to produce combined data representative of a vocal communication that substantially reduces or eliminates at least one of a first noise associated with the vibration signal data or a second noise associated with the tonal signal data;
wherein the vibration signal data is represented as a first fast fourier transform of the vibration signal, wherein the tonal signal data is represented as a second fast fourier transform of the tonal signal, and wherein the signal processor processing the vibration signal data and the tonal signal data to produce the combined data comprises the signal processor determining whether a first running average energy of the vibration signal is greater than a second running average energy of the tonal signal.
