An analysis of passive seismic recording performance
... Noise can enter through the digitizer power supply, through inductive pick-up in the sensors, signal lines or digitizer. Although resistive leakage in signal lines can be a source of noise, most noise is from EMI or EFI: Interference below 105 Hz is usually magnetically-induced, and is known as EMI ...

Sound level meter
A sound level meter or sound meter is an instrument that measures sound pressure level, commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental and aircraft noise. However, the reading from a sound level meter does not correlate well to human-perceived loudness, which is better measured by a loudness meter. The current international standard that specifies sound level meter functionality and performance is the IEC 61672-1:2013.
