Audyssey Introduces Its Latest Technology: Audyssey Low Frequency Containment

Audyssey LFC Prevents Low Frequencies From Going Through Walls

LOS ANGELES, CA--(Marketwire - April 7, 2011) - Audyssey, a global leader in audio technology for the home audio, automotive, mobile and theater markets, today announced Audyssey Low Frequency Containment, or Audyssey LFC. The new technology prevents low frequencies from traveling through walls, minimizing disruption in neighboring rooms or apartments with minimal impact on bass enjoyment.

Everyone, at one time or another, has been annoyed by the unpleasant thumps of a neighbor watching a movie or listening to music late at night. While high frequencies are easily stopped by walls, low frequencies go right through them.

"As home theater evolved over the years, bass became fundamental to the movie-watching experience. But for anyone in the next room or next door, it is also the biggest nuisance," said Chris Kyriakakis, Audyssey's CTO. "It's very difficult to acoustically isolate a room because it involves additional construction. We researched how bass wavelengths interact with wall materials and we created a technology that solves the problem at the source."

To attack the issue at its very core, the researchers at Audyssey first determined the range of frequencies that most readily pass through walls. Once the range was identified, they developed a process not only to reduce the level at those frequencies, but also to apply psychoacoustic processing that restores the perception of low bass for listeners in the room. Audyssey LFC is not a simple filter; rather, it dynamically monitors the low frequency range and engages only when it finds the offending frequencies. The result is a win-win situation for everyone. No more angry neighbors and no loss of enjoyment for listeners.

Audyssey LFC will first appear in AVRs in September of this year.
