- Hello all, Am a new member today, so I will give my hum-hearing
background. Have heard the hum loudly & intrusively & at times
unbearably so, since moving to a very quiet location in l999. It took
me a month or two to begin to notice it. Since then, it has changed
the quality of my life for the worse, but also provided some learning
experiences along the way, . . . ! I have heard it 24/7, with the
rarest of exceptions, for 4 years and counting. I can hear it outside
the house, when it is loud, but it dissipates as I walk away from the
structure (house). It is very noticable in the car, (enclosed
structure) when one comes into the driveway, even without the engine
turned off but very amplified with it turned off, Even when one is
not thinking about or expecting to hear it. Often it shocks me all
over again, that I have to actually live with this horrid pulsing
drone, with its' offkey pitch, its' erratic rhythm, and general
depressing and obnoxious tone, so very low and so very loud. Windows
open or closed, house or car, do not make a significant difference,
if any. It is worst in bedrooms, 4-sided of course!, and that makes
your last sanctuary, sleep, compromised. And so the problem grows, no
escape does seem unfair. What is this noise? When I was a neophyte, I
searched the local area, I put my head up against every imaginable
surface, I phoned my Hydro company, I hoped for an an electrical
outage, I asked neighbours, embarrassing & anxiety-provoking, if they
could hear it, I couldn't accept my roommates' inability to hear it,
asking too often, "Now can you hear it, can you hear it now?". I went
to an ENT doctor, I went to an audiologist, I spoke to very helpful,
really the first significant help, accoustic expert, Vibrasonic in
Vancouver, B.C. Canada. Then a Professor of engineering of some kind,
a bit of a genius accoustic people said, from the University of B.C.,
offered to test my house free of charge, as an ongoing exercise for
students. END of PART ONE!
- Dear Forum:
I have enjoyed greatly my interaction with this forum, but now I
find my e-mail too cluttered to continue on an active basis. (This is not
the first forum for that experience. Another, about Mooney aircraft owners'
affairs, became likewise saturated; too many messages and too little time
available to do justice.. etc.).
By now you have my e-mail address, and you may communicate
privately on the technical basis for hum.

Under "Edit My Membership" on the Yahoo groups website, did you know
that you have 3 options for message delivery to you? --
- Individual emails. Send individual email messages.
- Daily digest. Send many emails in one message.
- No email. Don't send me email, I'll read the messages at the Web
The Daily Digest option sends one daily e-mail containing from 1 up to
25 messages, and in additional daily batches each up to 25 messages,
depending on the number of daily messages. This option will
dramatically cut down on the number of e-mails that one receives.
The No Email option sends no e-mail, and one can use the Yahoo website
user interface for reading and replying to posts. This is the option
that I use, and I save my posts (and some others' posts) on my
computer by forwarding the post to my e-mail address.
