Hi all,
Im interested in building a type of oscilliator.. which send out high SPL sound Pressure waves, say like I got my hi fi loude speaker I want to put throught a high sound pressure ie (To feel it not exactly hear it..!!! is this possible..
the SPL in db Im after is about 140DB.. any help or links will very helpfull..
or does anyone know the frequency that Ive heard once, on a television Programe, that makes one blush.. red) as I remember its a really weird low hum.. dont know anything on that..
thanks in advance

140dB !
Your going to need a load of power and some very big and efficient speakers to hit that!
Like several of multi Kilowatt level amplifiers and about 6 -10 subwoofers that are around 15 -18 inches in diameter!
If you can get around that 20 hz mark at that SPL you will pee yourself.
That will make you blush very red!
Hi,
thanks for the replys,... perhaps I went a bit over the Top with the SPL level
(lol) .... I'm Just very interested in acoustics and the raw power of Sound..
A Audio hearing person.. in his training days... done a Joke on his colleges he set up a Subwoofer and put a certain frequency through the woofer.. and they really SH*t themselves..
how awfull is that...
thanks for the replys guys anyhow...!!
A note of a particular frequency that causes you to soil yourself.
Mythbusters concluded that no such thing exists, but only a fraction of the sentient beings on the planet actually want to believe them. They would much rather believe in overunity and HHO and other outrageous propositions.
Myth??? I don’t know!
What I tried to get the 7 story elevator shaft to resonate in the dorm at school. By resonating, it should take less power. It is hard to fins speakers that run well at 15-20hz.
I remember reading in an issue of Playboy magazine (yes I read the article too) there was a Brown Note at 57 Hertz. Police supposedly used it for crowd control
