How is pitch and intensity related?

The results, when plotted as equal pitch contours, show the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity,  the point at which the effect reverses varies with intensity level.

Explanation: brainlest??

the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.

Therefore intensity makes a tone lower or higher in pitch.

i think its y= -4x-14
