My guess, based on your description of a "whoooop" every few minutes, is
that it's slippage on the compressor clutch when it engages... if it's
coming from under the hood. I had a similar problem years ago with a '88
Integra. The air gap between the clutch and pulley can usually be measured
with a feeler gauge and it's probably too wide. In my case it involved
reshimming the clutch.
