So 7-volting gives about 11.7dbA drop, 9-volting 6.2dBA below the 12v noise level. With the perfect case, you'll lose 1/12 of your flow for every volt down you go, but with flow resistance it's a fair ...
Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...
