Hi Folks, A while back I asked for help in determining the source of =
some noise showing up on my Helicorder. This is an update to that =
question.
I have excluded auto traffic, as the noise happens weather it is =
weekends or work days, at about the same time.
I have excluded the schools in the area for the same reasons
I have excluded construction for the same reason.
I am not 100 percent sure of these exclusions, but for the most part, =
I think it is something else.
I have gone back several days on the Helicorder to see if I could find =
patterns, and I have found that all is quiet starting about 5:00 pm =
local time, 00 UTC. Things remain quiet until 08:35 am, 15:35 UTC. =
During the hours 8:00 am to 5:00 pm the noise comes and goes sometimes =
lasting less than one mins and sometimes lasting 5 to 10 mins.
The sensor, a Lehman, is in my basement. It is on a concrete floor =
next to a concrete wall, and the house above is wood and brick.
Could this noise be the sun? At about the time the noise begins the =
sun rises above the trees and shines on the east side of our house, =
which is also the wall near the sensor.
Could this warming of the wood and bricks, above the basement, and =
their expansion cause the noise. As the clouds block the sun during the =
day, might this cause the intermittent noise during the day? The noise =
stops about the time the sun no longer hit the house.
I could test this theory on a overcast day and I will do so, but I =
just wanted to get your input.
