Why Room Acoustics Matters

. You consider playing the clip on your car stereo, but you don't, because you know it just isn't the same thing. Besides the breeze and the ocean smell, what's the difference? Let's talk room acoustics. "But it sounded great in the store ...?!" We will begin our room acoustics discussion with a trip to the hi-fi store. The clerk eagerly whisks you into the inner sanctum of his shop: "the Grotto". Damped lights, walls covered with felt, and a leather couch right at the center ...

Your Room, from Interior Design to Acoustics

If you're into designing your own room, why not make sure it's perfect from an acoustics stand-point as well? Let's consider where we should put the TV and loudspeakers so they don't only look great, but sound great, too. My colleagues in Germany have modeled a living room with furniture and four speakers placed inside, with the goal of analyzing the eigenmodes of the room ...
