Perhaps I misunderstand this, but aren’t waveform arrays are meant more for uniformity than output? At least in the case of lightbulbs, adding 10 1800 lumen lights in an array would not result in additional light at any given point unless the light was focused, wouldn’t the same be true of sound?
- KaiserPro 6y agofor light, you are mostly correct. LED strips over a sheet with a diffuser produces a more useful light. But, as light is in the Thz range, doing any meaningful beamforming is exceedingly difficult. Because speakers are well within the range of controllability, its perfectly possible to alter the phase to steer the audio output. this is possible because changing the phase moves the peaks and troughs of the waves to "move" the sound to where its wanted.
