MEMS microphone with multiple sound ports

An acoustic sensor device, comprising:

• a package including at least a substrate and a lid over the substrate;
• a microelectromechanical system (MEMS) transducer formed in the substrate, the MEMS transducer comprising a cantilever structure;
• a first sound port on the lid above the MEMS transducer, the first sound port coupling the MEMS transducer to an ambient environment via a first acoustic channel formed in the package;
• and
• a second sound port on the substrate below the MEMS transducer, the second sound port coupling the MEMS transducer to the ambient environment via a second acoustic channel formed in the package,
• wherein positions of the first sound port on the lid and the second sound port on the substrate are such that the first sound port and the second sound port are aligned with the MEMS transducer in a manner that ensures that the first acoustic channel and the second acoustic channel have a combined second acoustic impedance that is less than a first acoustic impedance of the MEMS transducer.
