Prof Dr Malte Peter with the grating that the researchers used to test their predictions. The small black loudspeaker that generated the sound waves can be seen on the right-hand side of the grating's frame, while the microphone stage that travelled along the grating during the experiment to measure the propagation of the waves can be seen on the far right.
