Why is Room Correction Necessary?
To the left is a 2 dimensional simulation of a 1ms wave pulse
from a pair of conventional speakers into a room similar to the
above. Because the dispersion exceeds 60 degrees,
undesirable energy from each speaker is reflected back into
the room within a few thousandths of a second. This reflected
energy is out of sync with the original signal.
A few milliseconds later, the first wave-front is about to reach
the listener, while the reflected energy is close behind. These
early reflections alter the original tonal balance. As they occur
within the fusion time window, the brain cannot separate the
sounds.
