What is a common source of industrial noise?

Electric motors are a common source of industrial noise due to the mechanical and electrical processes involved in their operation. As electric motors operate, they generate vibrations from moving parts and electromagnetic noise from their magnetic fields. This noise can be particularly pronounced in industrial settings where motors are often used in large numbers for various applications such as conveyors, pumps, and machinery.

The high operational frequency of electric motors, along with their interaction with loads, can lead to significant levels of noise. In contrast, while transformers, computer systems, and wirelessly connected devices may generate some noise, they typically do not produce the same level of industrial noise commonly associated with electric motors. For instance, transformers mainly emit noise from the magnetostriction of their cores, which is generally at a lower intensity compared to that produced by electric motors. Therefore, the prominence and impact of noise generated by electric motors in industrial environments make them a significant source of industrial noise.
