Re: sound wavelengh and parabola size

["Jim Morgan" <>]

I ran a quick test on my dual science Telinga and found that at 50 and 60 H=
z
the gain was the same, however at 80 Hz there was a very noticeable increas=
e
in gain and at 200 Hz even more gain. All four frequencies were originally
the same power level.



So what I seem to be getting is a gain that increases exponentially with
frequency but with the lower frequency gain flat from 50 to 70 Hz. Didn't
test below 50 or over 200 Hz.



Klaus do you basically agree with this or am I miss interrupting my test.
