My apologies for not explaining what I wanted to do and why - can’t blame you all for being mystified!
Here goes: I suffer from tinnitus, and while there’s no cure, there are lots of remedies that help some people but not others. Trouble is, people try to make as much cash out of you as possible with these treatments, since T sufferers are so desperate.
One of the latest remedies is called ‘neuromonics’. With this, you find your T frequency by matching what you hear to a tone generator, then you listen to music that had had ‘white noise at this frequency’, as they describe it, overlaid onto it. You do this for many hours, then you switch to versions of the same music but without the noise. Miracle results have been reported (but then , they say that about every other T treatment).
The problem is, the people who developed this charge $5,000 for the treatment! And there’s no money back guarantee - they won’t even refund a portion of the fee.
So lots of T sufferers have been trying to do ‘DIY neuromonics’, since overlaying music with white noise is a simple matter.
But the big problem is knowing what ‘white noise at the frquency of the T’ actually means. If your T is a pure tone, of course, it’s a misnomer - the ‘white noise’ will be a pure tone as well. And the neuromomics people won’t tell you anything.
So, I’ve decided on trying white noise of maybe half or quarter of an octave, centred on my T frequency, and broaden or narrow it if that doesn’t show any results. But I want to be sure the cutoff is as clean as possible, and that the noise is centred accurately and has exactly the bandwidth I want.
I could mess about with equalisation curves, but maybe there’s a surer way, where you can actually type the frequencies you want into a dialogue box.
This is so important to me that I don’t want to do it by trial and error if I can get some expert advice on how to do a proper job. Thanks.
