JVC develops Near Speaker Surround Technology

September 11th, 2006 · No Comments

JVC has developed what it calls “Near Speaker Surround Technology” for 2-channel front surround sound systems.
The system applies proprietary signal processing to audio reproduced at low volume from a single active-speaker enclosure placed close in front of the listener. JVC says the result is a surround sound experience on par with a conventional multi-channel speaker system, all without any heavy noise leakage into the surrounding environment.
The company, which has three patents pending on the tech, will exhibit it for the first time at the four-day A and V Festa which opens at Pacifico Yokohama, Japan on September 21.
Near Speaker Surround joins existing JVC sound processing technologies 3D-Phonic and Root 4.
Using traditional components, placing a speaker close to a listener, sound volume can be turned down to reduce ambient noise leakage, but this typically results in a reduction of “spatial broadness” and impact. NSST restores this spatial awareness. The Japanese giant says NSST can create a soundfield equivalent to a sound pressure level of 70dB even if it reduces the ambient sound pressure by approximately 56 percent.
