Patent ID: 7693294

Claim:
A method of reducing the audible side effects of dynamic current consumption in a listening device having a plurality of subsystems, the method comprising: in a subsystem, executing at least one processing event within a processing window based on a timing schedule, the processing window being periodic; monitoring in-audio-band dynamic current caused by the at least one processing event, and transforming the in-audio-band dynamic current to out-of-audio-band dynamic current, including at least one of: after the execution of one processing event waiting a first time interval different from a second time interval defined by the timing schedule, and after the first time interval executing the other processing event so that the one processing event and the other processing event are spread out within the processing window; waiting a random delay time from a trigger event, and after the random delay time, executing the processing event based on the timing schedule; and executing a dummy processing event within the processing window.
