Or a calm, clear night in this case. I'm glad you enjoyed it. What this
recording fails to convey is the mind-altering sense of spaciousness which is
for me one of the Bay's most remarkable features. That's what I am hoping to do
with my homemade SASS.

Hi All,
Sorry for the slight off topic but there are many tech people here and I was
hoping someone could point me in the right direction...
I friend of mine is suffering from ME/CFS and as a result of that
she can’t even be exposed to the tiny radiation generated from most
electronical equipment. One of the things she misses the most living in this
18th
century style of life; is listening to music as the loudspeakers are really bad
to her. However, she can use a modified phone that carries the sound by pipes
conducting air pulses. Does any one out there perhaps know any way of
developing something similar to replace the loudspeakers and be able to listen
to music?
Headphones
are out of the question...
Any help is
welcomed, many thanks! you can answer me privately to
santiagoimberti@...
Cheers,
Santiago Imberti

Surely simply having them a long way away would be good enough to reduce the EMF
to background levels. How long are the pipes for the phone? And how is she going
to turn it on and off?
You could of course play music through the phone.
Are you able to provide some links to this aspect of the condition? I'm
sceptical.

Santiago,
Years ago I knew someone who was highly sensitive so I can sympathise.
I have two suggestions to try but I can't say either will work. It is
possible that high frequenies may trigger it as well as electronic
radiation.
Is it possible to try a cover like a blanket over the speakers to cut
the higher frequencies and/or grounded metal screens in front of the
speakers to baffle off any radiation. I don't know if you have fire
guards where you are, but they are made of fine metal mesh and look
OK.

Is it possible for her to use magnetically shielded speakers? I guess I don't
quite understand the implications of her disease.
In our 'contemporary' world, you do indeed need an electromagnetic transducer
of some sort to move the air in order to hear the sound.
So, no matter how you slice it, you need some electronics somewhere. And a
source of recorded sound or a radio receiver.
I know that they make special air-driven headsets for patients in MRI machines
so that they can listen to music. That would be fine, but again there is an
electromagnetic transducer located remotely to produce the driven air.
Perhaps the ideal solution is an old Victrola that is hand cranked. However, I
don't know if it could be modified to play modern LPs.
But the Victrola is a completely mechanical device, no electronics.
Maybe you can be more detailed about what exactly she can be exposed to and how
far away.
Is there any electricity in her house, i.e., mains wiring of 110 or 220 VAC?
Best regards,
Greg

Hi All,
Thanks for your suggestions and ideas.
Scepticism is indeed one of the main things they have to deal with. But I bet
any sceptic that gets to spend a few days with a ME pacient will soon cast those
doubts away. My friend history and links to more info on the disease can be
found in
http://www.cfids.org/about/catalyst-anne.asp
I'll go back to her with your suggestions and ideas to see how we can go from
there. But I having a acouple of questions/comments on your answers:
>Long horns, plus maybe
metal fiber clothing?what exactly are these? do you have any link to it?
>Maybe you can be more detailed about what exactly
she can be exposed to and how far away.
>Is there any
electricity in her house, i.e., mains wiring of 110 or 220 VAC?
She lives in Stockholm, Sweden so yes to electricity 220. She can be exposed to
some of the normal electrical things but for very shorts periods of time. If the
exposure is too long she suffers and it is detrimental to its health (hence my
initial quest for a way for her to listen to music for more than a few minutes a
day). So everything is turned off at the house most of the day.
In the case of the phone, the signal goes to a transformer for the air pipes
that are about 1.5 meters long. Since the electricity on the phone is very low
that seems to work all right.
Ok, that is for now, many thanks to all and I'll be glad to receive more coments
or ideas.

If it's ok for a phone to be 1.5m away, surely she can tolerate speakers, say,
3m away? I thought phones operated on about 50V, so not that low.
Does she have any way of measuring EMF levels? If not then I think getting a
meter might be the best way to proceed. Guessing what levels there might be
based on one's perception of how much power a device uses is probably not going
to lead to the most efficient solutions.

Dear all.
As some of you might know the natural circumstances for some seabirds have
been disasterous in the North-Atlantic ocean for some years. The Arctic Ten
is one of those speeces suffering from the global changes.
In big parts of Iceland hardly any Tern-chicks have been seen since 2004.
Therefor I and my wife were delighted when we saw some chicks of among the
Terns this evening.
Please feel free to enjoy the recording at

As Olympus and other pocket-recorders have been discussed on this list
recently I would like t draw your attention to the LS-11. In this recording
I covered the mics with a dead chicken from Røde and used the low-cut filter
due to the wind.

Thanks for listening.
Mostly, I use a Rode NT4 into a Sony MZ-RH10 mini disk recorder using the Hi-SP
compression.
I high attenuate frequencies lower than about 200Hz and boost the higher
frequencies starting around 2kHz.

Hi all
Recently I was out in the Nationalpark Thy in Northern Denmark, to record
ambiences just after sunset, when I came across an extremely weak humming-sound.
Barely audible without the recorder gain at max. It turned out to be hundreds of
mosquitoes inside a small forest. I started recording, and then when I made the
announcement into the mic, I noticed the mosquito-hum raising in pitch for a
short moment. I made different experiments, and it seemed they only reacted to
my voice each time, and not any other sounds I made.
Has anyone come across that phenomenon? Is it a known fact that mosquitos can
"hear" humans, and distinguish them from other sounds? I've never heard of that.
I put up the recording on SoundCloud, but it probably requires some good
headphones to hear the phenomenon:

I'm no authority on mosquitoes however I remember reading once that
mosquitoes are attracted to people (and other animals) by the carbon
dioxide in the breath that is exhaled... It was probably your breath
when you speak that excites them...

That is absolutely fascinating, and I could hear the effect very well, even
through simple computer speakers.
Perhaps the mosquitoes are attuned to the human voice since it implies a
source of food (i.e. our blood)? Whatever the cause, it is very interesting
- thank you for posting it!

I've heard the same thing... but not all of the sounds he made had the same
effect. And besides, I suspect (but of course don't know for sure) that he
was not near enough to them for his breath to have such an immediate effect.
And I presume he was still breathing, even while not talking... :-)

I did a little more listening and some Googling.
Google found this <http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1088611/>,
which includes a link to an interesting paper (Active auditory mechanics in
mosquitoes) which in turn shows female mosquitoes to be particularly
sensitive to sounds at around 250Hz, and males at around 450Hz.
Looking at a spectrogram of your recording, there are two distinct bands of
mosquito sounds, one centered at around 350Hz, the other at 700Hz. When you
speak, the frequency of each of these bands increases, then falls back to
its original level. When you whistle, and when the birds call, nothing
happens.
The obvious next step would be to play your recorded voice to them through
a loudspeaker, to see if it has the same effect.

Interesting phenomenon. It may be that the mosquitoes are reacting to the
increased CO2 that you are expelling as you talk. I believe they are
attracted to CO2 to help them find their food source. When you hummed with
your mouth closed, you may not have expelled as much CO2.
It would be interesting to see how they reacted to you blowing without
making any sound along with doing Ray's experiment to check the effect of
sound with no CO2.
You might want to wear some repellent for the test though!

Thank you for sharing.
A couple of suggestions on this "phenomena" has suggested CO2 or heating from
your mouth to your mic, but shouldn't the mosquitoes/mic have been reacting when
you whistle then?
At least to me it sounds like they react to your voice frequency.
I can be something else of course...
I might try to do the same experiment if I find the time.

mosquitoes inside a small forest. I started recording, and then when I made the
announcement into the mic, I noticed the mosquito-hum raising in pitch for a
short moment. I made different experiments, and it seemed they only reacted to
my voice each time, and not any other sounds I made.

"hear" humans, and distinguish them from other sounds? I've never heard of that.

headphones to hear the phenomenon:

anything very intelligent anyway. After all, they are only mosquitoes...)
