Room Acoustic Correction
In the second round of measurements, your room’s sonic characteristics are evaluated. Using this information, AccuEQ is able to prevent standing waves from forming by adjusting frequency response.
What is a Standing Wave?
Standing waves occur when sound waves of the same frequency collide, creating acoustic peaks in certain areas of your room. They are a result of sound reflecting from parallel wall surfaces and the floor and ceiling. Standing waves distort your perception of sound, meaning you don’t hear “the real thing”. Acoustic treatment panels can be used to absorb these peaks, but can be expensive and not practical for everyone. AccuEQ does the same job without the cost or inconvenience.
Speakers are generally measured and tuned in an acoustically “dead” chamber, free from unwanted echoes and standing waves. However, in the real world, every room suffers from echoes that can interact and change the levels of certain frequencies due to the effect of standing waves.
The combination of speaker tuning and the acoustic properties of your room changes how your speakers should actually sound. AccuEQ eliminates standing waves so the speaker sounds as the designer intended. Higher frequencies are untouched. The speaker voices the recording’s emotion with unique personality.
Peaks from standing waves negatively affect sound quality.
AccuEQ adjusts frequency response to eliminate peaks and improve clarity.
Corrected Frequency Response
Above chart shows the corrected frequency response (red), which now fits within specific level parameters. The result: clearer, more accurate sound.
Customization and Memory Presets
While AccuEQ fulfills the task of correcting your room’s acoustics so your equipment reaches its fullest potential, it’s true that everyone has different tastes when it comes to sound. We therefore include three memory presets you can use to save your own customized EQ settings, perhaps tailored to suit different content such as movies, music, or games.
