1. A method comprising:
receiving, by at least one processor of a device, a first signal representing an output by a piezoelectric micro-electromechanical system (MEMS) bone conduction sensor of the device;
receiving, by the at least one processor, a second signal representing an output by a piezoelectric MEMS acoustic transducer of the device, wherein the piezoelectric MEMS acoustic transducer is separate from the piezoelectric MEMS bone conduction sensor;
determining, by the at least one processor, that the first signal representing the output by the piezoelectric MEMS bone conduction sensor is indicative of an absence of voice activity; and
in response to determining that the first signal is indicative of an absence of voice activity by a user, generating, by the at least one processor, a control signal that causes the second signal from the piezoelectric MEMS acoustic transducer to be muted.
