JVC developed the "Near Speaker Surround" technology, which promises personal Surround sound without spreading loud noise, via a single speaker enclosure listening System.
The new technology applies JVC?s digital signal processing to sound reproduced with low volume from a single speaker enclosure placed close in front of a listener. According to JVC, the listener enjoys impressive surround sound on par with a multi-channel speaker system without heavy noise leakage into the surrounding environment.
With the spread of DVD software and digital broadcasting, it becomes possible to create a powerful multi-channel surround sound environment in the home. However, it can be difficult to find a place for rear speakers and wiring. Listening at loud volumes can bother neighbors as well. This generated the need for an easy-to-set-up system by which users can enjoy surround sound without worrying about noise leakage into the immediate environment.
JVC developed products featuring 3D-Phonic and Root 4 front surround sound technologies that enable users to enjoy surround sound easily. The new provisionally named Near Speaker Surround technology uses a 2-channel front surround sound system adds the new idea of considering how sound volume affects the surrounding environment.
This new technology provides a new listening style by placing a single enclosure-type dual speaker with built-in amplifier near the listener for listening to multi-channel content such as DVD software and digital broadcasting.
When any speaker is placed near a listener, sound volume can be turned down
to reduce ambient noise leakage. With typical technology, this results in losing the spatial broadness and impressiveness multi-channel surround sound can deliver. But JVC?s signal processing technology reproduces impressive surround sound with a sense of realism and broad spatial field that would not seem possible from such a speaker located close in front of the listener.
Each channel of the multi-channel signal is processed uniquely to create a binaural signal equivalent to what a listener would hear in a multi-channel surround sound field. This sound field is similar to what would be heard in a spacious theater, even though the speaker unit is placed near the listener.
Listeners get a surround sound effect by listening to sound with normal headphones when the signal generated by spatial acoustic field creation and processing technology is binaural. In reproducing this effect with two speakers, ?transaural processing? cancels undesired sound other than the binaural signal intended for each ear. In addition to this, JVC?s Near Speaker Surround technology adds unique signal processing to achieve sound image localization with minimal acoustic phase reversal and individual variation.
JVC will exhibit this technology at the JVC booth at the A&V Festa 2006 being held at Pacifico Yokohama from September 21-24 (Thursday to Sunday).
