Mark,
I installed an oil pressure gauge to know exactly what my pressures were.
After learning that my pressure was ok from the gauge, I replaced both
sensors with proper new pressure sensors.  This didn't stop the buzzer.  So
my "solution" was to ground out the high rpm sensor to the extra ground tab
on the distributor.  I also started running thicker oil, straight 50w,
living in a warm climate I was not worried about extreme cold dry starts.

So I guess my advice is to install an oil pressure gauge to really know what
your pressure is, even if temporarily installed(like getting a kit like I
did http://www.youtube.com/watch?v=1YxyNDV_xgY ) .   Could be worn
out/improper sensors, worn oil pump, or worn engine.... or any combination
thereof.

Ultimately I replaced my engine at 160,000 miles, had lifter issues and was
worn out.
I now have a permanent gauge up front <http://is.gd/bJW2i>.

good luck
