But, tracing the origin of the noise has been difficult because, apparently, not everyone can hear it. It could also be difficult to get the government to do anything about the hum as regulations typically only cover decibel levels that could lead to hearing damage or loss. Though, Dr. Darius Kohan, a neurotology at Lenox Hill Hospital and Manhattan Eye, Ear and Throat Hospital said that it is unlikely a low-frequency hum could cause damage to one's hearing.
