Abstract
A method for operating an induction cooktop having multiple induction heating coils includes monitoring a characteristic of the heating coils indicative of audible noise generated by simultaneous operation of multiple induction heating coils. Upon indication of audible noise from the monitored characteristic, an operating characteristic of at least one of the induction heating coils is varied so as to change the audible noise into a pre-defined, stored audible noise pattern that is desirous to a consumer or user of the cooktop.
