Why do I hear a low humming noise?
You hear a low humming noise due to a variety of reasons, including tinnitus, which is a condition characterized by internally generated sounds not coming from an external source, or electrical humming caused by ground loops, poor wiring, or electromagnetic interferences. The humming noise can also be attributed to household appliances, electrical devices, or even medical conditions such as Music Ear Syndrome, which triggers phantom music or sounds in some individuals.
