effect of loose air filter to U-tube connection

I removed the duct tape from the connection between the air filter housing outlet and the plastic U-shaped tube and then drove the car around. The noise was noticeably louder. I replaced the duct tape with an extra thick layer and the noise was muffled quite a bit. Verdict is that the noise is the air recircuation valve.

I have noticed in several threads that some people unplug the air recirculation valve vacuum hose. Is this advisable?
