You have available to you of two pump styles: pump A at 1000 gal/min produces a 100 dBA SPL at a given distance, and pump B at 500 gal/min produces a 90 dBA at the same position. For a noise control point of view, which combination of pumps would be most acceptable for developing a flow rate of 2000 gal/min? Explain.
