An experiment.

November 18, 2008

So I'm trying some experiements to see if I can find a path for us to

explore.

I've asked my exwife to send me some recordings of her speaking using

offending words and sounds. I will then take that recording and see

if there's a filter I can apply that will filter out the frequencies

that are triggering.

Just some quick experiments using my own voice seems to produce

positive results. Here's an FFT of me making an sssss' sound.

action=view & current=SSSS.jpg " target= " _blank " ><img

border= " 0 " alt= " Photobucket " ></a>

Here's an FFT of the same recording except that I have removed the

peak frequencies.

action=view & current=SSSS_filtered.jpg " target= " _blank " ><img

g " border= " 0 " alt= " Photobucket " ></a>

I wonder if our ears are amplifying the offending frequencies more

than others? These FFT's show how a microphone intrepts them, but of

course we may hear them differently. We would never know because

that is all we have ever known. Maybe they are not amplified by

them, but are tickled by them? (see my previous post.)

An FFT (fast fourier transform) is just an amplitude vs frequency

plot of a sound.

I haven't spent a lot to time honing in on the frequencies that are

triggering, but my inital stab seems to be between 9kHz and 11kHz.
