There are small speakers that can directly amplify the noise output, and judge the source by the sound to determine the size and frequency of the noise.
Plug directly into a wall outlet (power outlet), no battery required;
The speaker plays EMI sounds and amplitudes are demodulated to identify EMI sources (such as AM or shortwave radios, motors and arcs).
