Treat the Wall Behind the Noise. Maximum Noise Reduction: 12 decibels if noise source sprays noise out into room, 46 decibels if noise is sprayed directly onto wall (such as noisy vent on the back of a machine). Advantages: No inconvenience to workers How much QFA? Treat the wall behind the machine with about twice the square footage of the "noise shadow" of the machine on the wall.
The Control philosophy controlled to a mill load setpoint by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was incorporate an additional loop whereby mill speed is automatically adjusted to control mill weight/load.
