Abstract

An acoustic module includes a plurality of acoustic sensor devices and a plurality of sound ports configured to couple the plurality of acoustic sensor devices to an ambient environment. The plurality of acoustic sensor devices includes at least a first acoustic sensor device and a second acoustic sensor device. The plurality of sound ports includes at least a first sound port, a second sound port, and a third sound port. The first acoustic sensor device includes a first transducer having a first side coupled to an ambient environment via the first sound port and a second side coupled to the ambient environment via the second sound port. The second acoustic sensor device includes a second transducer exposed to the ambient environment on one side via the third sound port. The first sound port, the second sound port, and the third sound port are positioned in the acoustic module such that the third sound port is at least approximately aligned with a midpoint between the first sound port and the second sound port.
