|The Best Sound For Your House|
A new technology allows that to any listener of a audio/video system benefit of the best seat, independently of the place where we locate the advance will be without a doubt of great interest for more and more the numerous proprietors of an equipment of cinema in house, since thanks to him, up to eight people will be able to enjoy their sonorous quality, exactly experiencing the same sensation of surrounding sound.
The system is one of first that applies the diffuse?lógica? to the audio one, assigning rules to the data of sound and providing instructions to a processor so that it can give priority to certain information. In the equipment of cinema in house installed in a means room so large, the best sound always experiences the listener who is in the middle. The other spectators of a film can hear too displaced the special effects of a scene, which reduces the intensity of the auditory experience. After years of investigations on how the humans we perceived the sound, the engineers of audio have introduced the new software in the amplifiers?home to theater? that automatically he detects the acoustics of the room, the situation of the loudspeakers and another information with respect to eight different points, to process the sound later so that each listener can enjoy the best seat. The system is called MultEQ and has been developed by Chris Kyriakakis and its colleagues of the Audyssey Laboratories, Inc.. The technology is product of its investigations around the call?audio-immersion, made in Integrated Media Systems Center (IMSC) of the University of Californian Southern. The MultEQ algorithm uses the data provided by a microphone placed by the listener in anyone of the listening positions. Then, the equipment of audio is calibrated emitting a tone of test through the main and surrounding loudspeakers, a tone that is modified by the unique characteristics of design and situation of each loudspeaker. The listener will repeat the process for each place (for example, for the three seats of sofa '). During normal listening, each position will receive a phantom of different sound. During the calibration, the MultEQ detects how different is each position of listening and it compensates them independently, modifying the sound of simultaneous way to improve the experience of each person in the room. The same method can be used in other surroundings, like the interior of automobiles, where the reflections produced by the windows and other obstacles, like the proximity with certain loudspeakers, can affect to the listeners located in the seats. The system also will serve so that the musicians can try with orchestras located to thousands of kilometers, without for that reason they must feel remote of the group. They will experience the same sensation that if they were in the middle of all its companions.
