Abstract
An acoustic sensor module includes an acoustic sensor device including a transducer and an enclosure configured to encapsulate and seal the acoustic sensor device within the enclosure. The enclosure includes a first sound port configured to couple a first side of the transducer to an embodiment environment via a first acoustic channel formed in the enclosure. The enclosure also includes a second sound port configured to couple a second side of the transducer to the embodiment environment via a second acoustic channel formed in the enclosure. The enclosure additionally includes a notch formed on a surface of the enclosure. The notch is configured to enable detection of a leakage path, within the enclosure, between the first sound port and the second sound port around an outside of the acoustic sensor device.
