Systems and methods for adapting the performance of an acoustic communication link with an implantable medical device (IMD) are disclosed. An illustrative method includes initiating an acoustic link with the IMD, measuring an initial performance of the acoustic link, determining whether the initial performance of the acoustic link is adequate, adjusting an operating parameter related to the acoustic link in the event the initial performance of the acoustic link is inadequate, measuring a performance of the acoustic link in response to the adjusted operating parameter, and setting the operating parameter to a prior setting if the measured performance of the acoustic link does not improve in response to the adjusted operating parameter.
