High and low speed fans sound the same.

[Twisted2]

If my fan is running on what I believe to be low speed, and I turn on the A/C, the sound of the fan doesn't seem to change. This is as heard from sitting inside the car. Should the two speeds sound drastically different?

I wonder the same thing myself.
