Method for sound reproduction in reflection environments, in particular in listening rooms

Abstract

The invention relates to a method in which, primarily in listening rooms, instead of the spatial sound of the respective environment, the spatial sound of a third room can be made substantially enveloping in the perception of the listener. The third room spatial acoustics perceived instead of the listening room spatial acoustics act in the same way in terms of hearing physiology as the spatial acoustics of natural rooms, namely enveloping in terms of the spatial sound (in distinction to direct sound). This type of spatial enveloping effect can also be incorporated emotionally by the listener into the auditory event, and has no sweet spot problem (there is a large preferred listening area instead of a preferred listening spot) and lets deep frequencies take effect in a way through which subwoofer speakers can generally be omitted.

Description

technical field [0001] The invention relates to a method for playing sound in reflective environments, especially in listening rooms. Various methods are known in the prior art for playing sound in a listening room, in particular via one speaker (mono), via two speakers (stereo) or via four or more speakers , where two front speakers and two rear speakers (so-called 5.1 surround playback configuration) with a central speaker and optional woofer in surround playback have been established in the market. In order to enhance the stereo sound experience, especially in the field of home audio, in recent years it has increasingly also been possible to provide additional loudspeakers, which are also placed partly in the upper part of the listening room and are oriented here at the listening position, and technologically advanced movie theaters use a large number of additional speakers. Background technique [0002] Here, particularly large gains are made in the area of ​​spatial p...

Problems solved by technology

However, even in this method there is the above-mentioned problem: the diffuse sound of the excitation of the listening room is in many cases and especially when playing music not suitable for the audio played and for this reason lies between the direct sound and the spatial sound. The balance of the ratio tends to be affected by
