WebBeamforming microphone arrays are always circular and come in three main patterns: random, spiral, and ring. (In contrast, NAH microphone arrays are always rectangular.) The ring array performs well when the exact distance to the source is unknown, but it lacks dynamic range. The spiral array gives better results, but you can generally achieve the WebIn der Akustik. In der Akustik wird Beamforming meistens dann eingesetzt, wenn Messungen in der Nähe des Messobjektes nicht oder nur mit großem Aufwand möglich sind, z. B. bei landenden Flugzeugen oder vorbeifahrenden Zügen. Daher wurde in der einschlägigen Literatur auch schon der Begriff „akustisches Teleskop“ eingeführt. Die …
