not enough data, seriously
not all pumps make the same, or same amount, of noise
the MCP600 goes from DEAD silent to fairly silent, a function of the tolerance stack of the rotating parts
so which MCP600 do I select for testing ? need a sample to do correctly
and the only MCP650 I have is a prototype, regular units here this week; then I will need to hear a number of them to get a 'feel' for the variation between units
Gabe and I both did a 'sleep test', pump in a loop in an empty case at night in the bedroom
- below the background noise level, but that doesn't say much
