Ambisonic rendering is a way to simulate the precise locations of sounds in 3D, and an ambisonics algorithm has allowed researchers to create rich virtual ‘soundscapes.’Researchers decided to test the limits of ambisonic sound reproduction through their ‘AudioDome’ loudspeaker array. Humans’ spatial acuity is high in front of our faces but decreases around the sides of our head, and the researchers’ experiments obtained very similar results from listeners in the AudioDome, proving that the loudspeaker array can reproduce sound locations at a spatial scale beyond the human limits of perception.
