摘要： The present invention is directed to systems and methods of distinguishing acoustic noise from valid plate contacts in vibration sensitive devices such as vibration sensing touch panels. The energy content of the detected vibration spectrum can be analyzed for features characteristic of noise, for example a higher relative contribution from high frequencies due in part to preferential coupling of above coincidence frequencies over below coincidence frequencies.
