What would cause a knock sound in the dash after turning off the AC-heat?
The knocking sound could be the doors of the vents closing when you turn it off,they are controlled by vacume.Or it could be the plastic making the sound due to change in temperature. If it is a early to mid 90's Chevy it is most likely the actuator solenoid that controls the recirc or fresh air. If it is it will knock for about a minute and 30 seconds when you start the vehicle and about the same wheen you turn it off.
Most likely a bad hub. Try turning the steering wheel right or left and see if the sound changes or goes away while turning. If it goe away or significantly changes when you turn left it is probably the right hub and vice versa when you turn the other way. If you hear a popping sound when turning it is the constant velocity joint.

A solid surface like thick glass with little give will reflect sound towards the listener more than it absorbs it. Beware of turning the sound up too with much with thin glass and finding the resonant frequency of the glass. This will cause constructive interference and cause the glass to bend until it shatters.

It comes like any other sound. Since lightning displaces a column of gas by turning it into a hot plasma, and it does so very quickly, the sound is very intense. So if the thunder does not originate on very flat land, there will be very many echos that cause it to sound like it "rolls". Even thermal gradients in the air, or density gradients made by falling rain can cause echos.
