1. A method for beamforming audio signals received from a microphone array, the method comprising: receiving, by an electronic processor communicatively coupled to the microphone array, at least one audio signal from the microphone array; determining a plurality of beams based on the at least one audio signal; receiving, by the electronic processor, from a vibration microphone communicatively coupled to the electronic processor, at least one vibration signal; time aligning the at least one audio signal and the at least one vibration signal; determining a plurality of correlation values, each of the plurality of correlation values based on one of the plurality of beams and the at least one vibration signal; determining a peak correlation value based on the plurality of correlation values; and selecting one of the plurality of beams based on the peak correlation value.
