A hearing device and subassembly therefor includes a sleeve member configured for at least partial insertion into a user's ear canal, the sleeve member defining a cavity that receives and retains at least a portion of a sound-producing electroacoustic transducer. The sleeve member includes a cable interface, wherein an electrical interface of a sound-producing electroacoustic transducer received in the cavity is accessible via the cable interface. The device also includes on or more sensors integrated with the sleeve member and positioned to sense a biomarker or other condition when the sleeve member is at least partially inserted into the user's ear canal. The hearing device includes conductive traces integrated with the sleeve member, where at least one conductive trace is electrically connected to the sensor and electrically connectable via the cable interface.

Receiver housing with integrated sensors for hearing device

A micro-electromechanical system (MEMS) transducer assembly includes a transducer including a condenser microphone, an integrated circuit electrically connected to the transducer to receive an output voltage from the transducer, wherein the integrated circuit comprises a test signal generator configured to induce a test acoustic response in the transducer, and an evaluation circuit configured to compare the test acoustic response to a baseline acoustic response to identify a fault in the transducer.
