An implantable medical device having an acoustic element includes a control module coupled to the acoustic element, an acoustic sensing module coupled to the control module, and a patient alert driver module coupled to the control circuit. The patient alert driver module generates a patient alert drive signal for activating the acoustic element to emit a patient alert signal. The control module includes an isolation circuit for isolating the acoustic sensing module from the acoustic element in response to the patient alert drive signal.
