Roy,
re: LFA Sonar / US Navy
I checked and read http://www.oceanmammalinst.org/mgpaper.html
which is very interesting and concerning.
Beside myself I know of others within your list who are suffering of
tinnitus (ringing in the ear at different noise levels). My tinnitus (in
both ears, two steady high pitching noises, sometimes additional 3. and
4.intervalling noises) started 10 years ago and bothers me for 24 (!) hours
a day; there are times when the noise level decreases a bit, but never
disappears; a the maximum loudness I feel like lacking energy.
I wonder whether radio and micro waves could possibly cause tinnitus as
well. I remember that about 10 years ago the first cellular phones were
introduced here in our valley.
Maybe others from your list with tinnitus could give a short report about
their tinnitus suffering and whether they are aware if their tinnitus
started also with the introduction of the cellular phone in their area.
Can anyone help me to give some clarifications:
1 Can Low Frequency Active Sonars (referring to above mentioned article,
see web site) be classified within the ElectroMagnetic Spectrum, as are the
electromagnetic fields (power line- and microwave frequencies)?
2. What is a comparative sound of 110 - 120 dB, can humans hear it?
3. What does dB stand for? Could you give another sample for dB (in
Dummies' language), like using the water hose to demonstrate Voltage,
Current, Power, Conductor etc.
4. What is the human's ear range in dB? Below AND above that range, are
you aware of any possible damage/negative side effects to the ear? If there
are negative effects to the human ear, what are they?
5. If I assume that the dB range is within the human hearing range, which
frequencies within the electromagnetic field (within our EMF/EMR debated
issue) are you aware of that can cause adverse effects to the human ear?
What are the effects in case you are aware of? .
6. What about the ears of domestic animals (cats, dogs, horses, cows: any
known studies that report about negative effects or damages to their ears
caused by
a) Low Frequency Active Sonar
b) radio/micro waves.
If there are studies available, please give references.
Thank you, Hans.
PS.: It is us, who have to dig up and present the already existing but
hidden information about EMFs/EMRs' adverse health effects to the ignorant
& biased industry/government!
