I know what it is....but then again I don't. What does it sound like? What should I be listening for to determine whether I have it? Just curious... Thanx
During very loud bass effects, you can hear port noise as a "chuffing" sound. It is basically turbulent flow of air in the port which is audible. Spread your fingers apart and blow your breath with pursed lips through them with about 8 inches between your hand and lips. That roughly approximates the sound of port noise.
