How does background noise affect measurements?

Background noise can cause considerable error in measurement when the background noise level is close to the level of the noise source of interest. When it is not possible to eliminate or reduce the background noise, a correction factor may be applied to the overall measurement to find the level of the noise of interest. The user must first make a measurement of just the background noise, without the noise source of interest. Then make another measurement with the source of interest. If the difference between the overall measurement and just the background noise is greater than 7dB, then the error due to the background noise is less than 1dB.
