A Site Survey is also done with a Sound Level Meter. It is done a specific work area. For example, at Hobbs Fibers the entire plant is not loud. Only the 3rd line and 4th lines are loud. These lines have manufacturing processes that create a lot of noise. You can use a sound level meter to measure the noise from that machine.
