Abstract: There is disclosed a computer-implemented method of generating audio signals for an array of woofers and an array of tweeters housed in a computing device, the method comprising: receiving a plurality of input audio signals to be reproduced, by the array of woofers and the array of tweeters, at a respective plurality of control points in an acoustic environment; and generating a respective output audio signal for each of the woofers and tweeters by applying one or more cross-talk cancellation algorithms to the plurality of input audio signals to control a pressure at each of the plurality of control points, wherein the array of woofers consists of two woofers and the array of tweeters consists of at least three tweeters.

Abstract: A monitoring device for monitoring a screw joint of an object includes a base plate to be attached to the object and a top plate to be attached to one part of the screw joint, wherein the base plate and the top plate are positioned parallel to and on top of each other and wherein both plates each includes at least one electrode that capacitively interact with each other. The monitoring device is characterized in that the electrodes are shaped and positioned such that at least one electrode of one of the plates interacts with at least two different electrodes of the other one of the plates depending on the rotational position of the plates relative to each other. A monitoring arrangement having at least one monitoring device of this kind and a monitoring method are also provided.
