is this "the hum" some people complain about in cities?
- baerrie 3y agoPossibly? In this paper they say the frequency needs to be between 2.4-10,000 Mhz and to be over a certain power threshold. Also the individual needs to be within a certain distance and have sensitive enough hearing (over 5000 hz).
- svilen_dobrev 3y agoprobably not. There is very low-freq hum in cities (because of cars wheels, airconds, all those rotating+vibrating things), which can be (un)heard if one goes above and then beyond/down edge of some hill at end-of-city - and will stop hearing it (absorbed by earth mass). But it is difficult to "hear" inside the city as your body also vibrates with it..
- NikkiA 3y agoNo, the hum is around 80Hz normally. This is much higher frequency.
