Changing the playback room size

[syntheticwave]

The most important deterioration during the reproduction process is caused by strongly differences of the playback room regarding the recording room. As far as a sound event becomes reproduced in the original recording area a formidable perception is firmed normally.

Unfortunately we cannot really adapt the playback room acoustics until. Possible is only treatment in the frequency domain. That adapts the coloration of signal and reverberation, but we cannot adapt the size of the reproduction area until.

By a new procedure become possible such changes virtually by retarded radiation of the first reflections. The procedure is very expensive because near field rendition by a huge speaker field, working by the acoustic curtain principle would be need. It becomes able to enlarge or decrease the virtual playback room size. More info is available by www.wave-field-synthesis.de.

Should such principle become the solution of the most acoustically caused problems?

Another way to acoustically double the size of your room is to lower the temperature to -327 deg F,which will cut the speed of sound in half...

Also very expensive,and VERY low WAF. :-(

Hi Don,

formidable thougth! Its -199,4 degrees Celsius, I have set this value in the http://www.syntheticwave.de/Download/Speakerfield.xls
Excel. You see by the speaker elevations, it works, doubled wave amount caused a doubled perceived seize! If you activate the macro it moves the waves by the RUN button.

But what would be you way for warming up the listener?

Your proposal woud have one advantage: The WAF would be fast increasingly if your wife would watching the picture longer as 10 minuts.
