Problem Curve
: Here is a problem curve. The small variations in blue are OK. They are 2dB or less and
you likely will never hear them. However, the variations in the red circles are bad. While the ear is not so
sensitive to dips in the response, it is very sensitive to peaks. The response peaks are what makes a
speaker sound "harsh" and cause "ear fatigue" (You listen for a while then turn it off because it starts to
irritate your ears). With this curve you want to pull down those peaks to put them in line with the rest
of the signal response. Once that is done the system should sound just about right.
