Iosono是一款由弗劳恩霍夫研究所和Iosono GmbH于2004年推出的音频系统，基于波场合成技术。该技术源于荷兰代尔夫特理工大学在1980年代的发展，通过特定算法生成必要的次级声波，再由大量扬声器（约300-400个）协同工作，将三维音频场景在房间内重现，提供全面沉浸式的听觉体验，超越传统环绕音响系统只能在有限区域内的‘甜蜜点’再现原始三维声音。

Iosono is the product name of an audio system presented by the Fraunhofer Institute and the Iosono GmbH in 2004. It is based on wave field synthesis, a method to use secondary audio sources to recreate primary wave fields, that was developed at Delft University of Technology in the Netherlands in the 1980s.
Given a 3D audio "picture" of the scene, a specialised algorithm generates secondary sound waves necessary to recreate it in the particular room and then instructs a large number of speakers (300-400) to generate the "audio hologram". While traditional surround sound systems can only recreate the original 3D sound in a small "sweet spot", Iosono claims it can recreate the original audio in the whole room.
