How do you measure low-frequency hum?

Sound level meters can be used to measure and quantify low frequency noise. Class 1 sound level meters (as defined in the standard IEC 61672-1) will provide more accurate measurements at low frequencies as they are required to meet stricter tolerances and have a wider frequency range.
