  • Dynamic Speaker Management with Echo Cancellation
    Publication number: 20140135078
    Abstract: A system for echo cancellation includes a dynamic speaker management (DSM) module, a current/voltage sensing amplifier, a sound pressure level (SPL) model module and an echo canceller. The example DSM module is receptive to a far-end signal and is operative to develop a modified far-end signal and a plurality of parameter outputs. The example current/voltage sensing amplifier is coupled to the modified far-end signal and develops an amplifier output, a voltage (V) parameter output, and a current (I) parameter output. The example sound pressure level (SPL) model module is coupled to the plurality of parameter outputs of the of the DSM module and is operative to develop a predicted SPL. The example echo canceller module is responsive to the predicted SPL and to a near-end signal and operative to develop an echo-canceled output signal.
