I’ve been trained to ignore that sound. That didn’t answer your

Sounds like you need to check the batteries in your noise cancelling
headset. Those pumps come with different output pressures so pick the
appropriate pump for your system. The pumps I installed in 211LF 20+
years ago have in excess of 1000 hours now. I tested them for possible
back flow and installed them in parallel without check valves.
