First, the system runs measurements to find out how a room-and the positioning of the speakers and listening chairs within that room-is affecting the sound, and then it figures out how it can adjust the sound to hit that target curve. Room-correction systems employ what’s known as a “target curve,” a certain balance of sound frequencies they’re trying to achieve when you’re sitting in your favorite listening chair.
If the system’s designers ignored good audio science, it could end up producing a boring, dull sound-or an unnaturally glaring sound. If it fails to correctly determine your speaker configuration, for example, it can make voices sound boomy or thin, or create distortion that makes the system sound harsh. The sound may also become more enveloping.Ī bad room-correction system does the opposite.

Movie dialogue will sound more realistic, not harsh, thin, or bloated. Explosions in movie soundtracks will slam rather than just boom. The notes in a bassline will have the same level as they do on the original recording. The goal is to correct for the effects that a room’s acoustics have on the sound by using microphones to analyze different sounds emitted from the speaker(s) and tailoring the sound accordingly.Ī good room-correction system makes the sound more natural and pleasing. Room correction is built into most AV receivers, many subwoofers, a few pieces of stereo gear, and even some wireless speakers from Sonos, Amazon, and Apple. Fortunately, the automatic room-correction system built into your audio components can do the job for you-but unfortunately, not all room-correction systems do the job equally well. Correcting for those effects requires a solid understanding of physics, familiarity with some key bits of audio research, and a specialized microphone and audio-measurement software. The shape, size, and contents of a room have a huge, and often negative, effect on how an audio system sounds.

But figuring out how to make speakers sound their best in a particular room comes pretty close to rocket science. Speakers sound different when you use them in different rooms.
