Having a Vacation Rental here in North Central New Mexico, I have ..one at least 6 occasions, had people ask how close to Taos we are. The reason invariably, is that they are affected by the low frequency Taos Hum that eminates from the Taos area and radiates up to 60 miles or more.
Normally my response is about 60 miles. Not one has ventured here!
Once, I was camping, and could have sworn I heard "The Hum'. Turns out is was a gang of hummingbirds in a juniper tree ..um..having a party!
Another time, as we doing some construction here and had lines strung ...I thought I heard 'The Hum' for weeks, only to discover that the wind was 'playing' the string we had strung! Shucks!

The Hum is a generic name for a series of phenomena involving a
persistent and invasive low-frequency humming noise not audible to all
people. Hums have been reported in various geographical locations. In
some cases a source has been located. A well-known case was reported in
Taos, New Mexico, and thus the Hum is sometimes called the Taos Hum.
Hums have been reported all over the world, especially in Europe. A
"Hum" on the Big Island of Hawaii, typically related to volcanic action,
is heard in locations dozens of miles apart. The Local Hawaiians also
say the Hum is most often heard by men. The Hum is most often described
as sounding somewhat like a distant idling diesel engine. Typically "the
Hum" is difficult to detect with microphones, and its source and nature
are a mystery to the listener.
The "Hum" is sometimes prefixed with the name of a locality
where the problem has been particularly publicized: e.g., the "Bristol
Hum" or the "Taos Hum". It is during the 1990s that the Hum phenomenon
began to be reported in North America and to be known to the American
public, when a study by the University of New Mexico and the complaints
from many citizens living near the town of Taos, New Mexico, caught the
attention of the media. However, in the 1970s and 1980s, a similar
phenomenon had been the object of complaints from citizens, of media
reports and of studies, mostly in the United Kingdom but also in other
countries such as New Zealand. It is difficult to tell if the Hum
reported in those earlier cases and the Hum that began to be
increasingly reported in North America in the 1990s should be considered
identical or of different natures. During the last decade, the Hum
phenomenon has been reported in many other cities and regions in North
America and Europe and in some other regions of the world.
