Systems and methods for beamforming audio signals received from a microphone array. One example embodiment provides an electronic device. The electronic device includes a microphone array and an electronic processor communicatively coupled to the microphone array. The electronic processor is configured to estimate an ambient noise level. The electronic processor is configured to compare the ambient noise level to a first threshold and a second threshold, the second threshold being lower than the first threshold. The electronic processor is configured to determine a beam pattern for the microphone array based on the comparison of the ambient noise level to the first threshold and the second threshold. The electronic processor is configured to apply the beam pattern to an audio signal received by the microphone array.
