How loud are you supposed to play the white noise? I presume on headphones.

The white noise is supposed to be played back at the same volume the tinnitus manifests itself.
That white noise MUST be notched at the frequency of the Tinnitus itself. Using not notched white noise won't do anything.
I use headphones but may work on speakers as well.
Don't think people around you may like a constant (low level) background noise for an hour or so.
As soon as the white noise is switched on (in my particular case) and the volume adjusted the ringing grows louder after a few seconds.
I re-adjust the volume now and then.
After an hour of listening (doubled the time myself) I still hear the ringing a bit louder.
As said... notching above 8kHz has not proven to be very effective.
I still hope more improvement can be had but sofar it is just lowered in amplitude a bit.
Of course taking multivitamins and not exposing myself to music might have been accountable for the effect as well.
Maybe it's the notching therapy.
In any case I should continue this 'treatment' daily for several months to be sure IF it really does something in my case.
Everyone's Tinnitus may be different, different causes, different manifestations, different reasons.
As I just woke up one morning I supspect it's a brain issue and hope to be able to 'teach' my brain otherwise I will have to learn to deal with it.

I think I found out a bit more about my Tinnitus.
Sometimes it is caused by a (partially) blocked ear canal.
I had that a while ago and had my ears rinsed.
That didn't go as it used to go (have had my ears rinsed before)
When I had this and my ears got rinsed the water came out quickly and had 'hyper hearing' with extended clarity for about an hour or so.
Then hearing went back to 'normal' again.
The last time it did not happen and the nurse said there is still water in there.
Seemed plausible.
The brain is a mighty thing and adjusts L and R ears to be the same even if they aren't in reality.
When one ear is partially blocked and builds up slowly the brain simply increases the gain so you hear 'balanced'.
When this is undone (rinsed) the brain has to re-adjust for the greater clarity again and dials back again.
When one ear has a smaller FR (due to blockage or whatever) the brain dials up the gain for high frequencies to match that of the other ear.
I noticed the peep of 13kHz had gotten a second (lower piched) beep as well so matched that one as well,
The website mentioned that with notched noise therapy the notch needs to be checked and readjusted as normally it lowers in frequency during the 'treatment'.
That seems to be the case here as well.
11.6kHz so filtered that out as well now and will continue.
At the same time I noticed I could hear up to 14kHz on the right ear but the left ear was much softer and cut out at about 11kHz.
So it supports the idea that the left-right balance issue is what causes my problem.
Will start dropping drops of oil in my ear again to soften the wax.
See if it clears and if not back to the GP and have it looked at again and have it rinsed again.
Hoping this can still be resolved and isn't an age thing.

It's good that something is shifting, Frans. Probably a sign of not being 'age related' since if it were, it would probably stay put whatever you did.
My hearing is reliable up to 14khz and after that, either the headphones or my ears drop away. Probably a bit of both. The noise I get is just under what I think is the threshold of my hearing but very difficult to determine the pitch.

Well when you use your Sennheiser HD650 you can rest assured that it runs all the way up to at least 30kHz. Double that of what we can hear. Took me quite a while to determine the frequencies. After notching one hour the 11.6kHz is gone again. Leaving only the more irritating and louder 13kHz. You can try this one: www.audionotch.com/app/tune/it can also sweep with noise bands. |

Sorry to hear you're hearing cranial test tones, Frans. Just more evidence that youth is wasted on the young. ;-)
My parents and siblings have suffered from tinnitus and I'm starting to get it too. I like to consider it my auditory bias signal. Fortunately, so far, it's been at a low perceptual value so I can 'bias' it out. However, it is always present with an eery left-right stereo effect that is neither in my head or out of it, existing in a soundstage dimension of unknown origin.
OUCH! Took the audionotch test and didn't notice the volume on my SS amp was turned up. Ouch! A good tube headamp wouldn't hurt like that, right? ;-) Not sure of the exact frequency for me, but my sinuses are cleaned out and any ear wax deposits melted away. Thanks, internet! LOL!

Oh ..... I forgot to say.
This also might help .. it does with me, I think.
Drink more water!!

Oh ..... I forgot to say. This also might help .. it does with me, I think. Drink more water!! Yes Ian. And too much coffee really kicks it up. Interestingly enough moderate amounts of alcohol seems to kick it down. Seems to make sense since the theory goes it's caused by overactivity in certain neurons in the auditory centers. But can't be drinking all day. I have read some doctors have had some success with benzodiazepines. There is a phase 2 drug trial going on with something called OTO-311. It's injected into the ear, and is an extended release drug. Quite a number of people have shown significant relief. But it's not approved yet, so a few years away. Lots of other drugs being tested as there is now a market for it now. Combat veterans. Who knows we may be able to get our youthful hearing back one of these days. --You can tell I haven't had my coffee this morning with all the edits I done! |

I don't think I'd like to be one of the 'dummies' for testing, Ron. Injections into the ear?  BTW, my old Sennator has gone back to be looked at, but I now have a portable Kameleon here thanks to Syd. It's tremendous. I'm really chuffed with it. I haven't got batteries in yet, so it's running off a USB charging lead (5v) and the Senn is back to its former glory. Now, I can play that quite loud and the ear noises don't worsen........ Could be headphone peaks? |

Are you using the HD650 filter? Using the SeNNator as a pre into the Eddie Current Black Widow I can listen at lower levels, but hear everything clearly, and deeper into the mix. I really thought using the two amps would cause a decrease in clarity but it doesn't. Except maybe at the highest frequencies where they might be rolling off just a bit. Hard to say it's subtle if it's even there. It is amazing how it fixes the bass issues with the 650. Not boomy one note bass, but deep and clear. Each note on the bass guitar, especially if it was direct injected sounds distinct. Do you hear the bass that way as well? Enjoy your new toy. Maybe Juke will make you one if you ask nicely.  |

Yes, I put the hd650 filter into it and the dt770 into my mains driven. The Sennator is having a Dutch holiday.
I hear a very deep, rubber band like bass!! It is quite physical feeling at times because it can go so low. Funny thing is that on some recordings, there is no bass and on others, it's gut wrenching.
Even an IPod Touch works with it. Volume is absolutely fine and the IPod output isn't too good really. Quite weird using an hd650 with an IPod but even podcasts are vastly improved. Way more natural sounding.
Syd has done me proud!!! I saw this little portable out of the box this morning and took a listen, expecting maybe a lesser mains driven like sound. Not at all. I instantly fell for it plus the fact that Syd is an amazingly neat builder. Looks drop dead gorgeous.
I first noticed just how good he is a few years ago when he sent me a configurable amp he'd made. The build again was superb. He's very talented.
So a panic set in. Should I supply my friend with this or pretend it's not available. Well, he ain't getting it, I've decided now. It's just too good to sell off to someone using a Sony Mdr1a!!!
Syd has a second unit which he's sending down to me would you believe so I'll just get another pair of batteries and a lead for him.
The portable units are way better than I thought tbh. So now I have one for the hd650 and another for the ct770. When the Sennator comes back, I'll have to decide what filter to put into the third one. My mate wants an Mdr1a, and for me, I wouldn't mind something portable either. Either an Mdr1a (which I can try when it arrives) or something else. Trouble is that there aren't filters for MSR7 or vmoda yet. Spoilt for choice, I am.
I must admit, I'm very taken by the portable unit since it works plugged in without charging or portable. Serves two uses.

Sounds like an early Christmas for you! All those choices. Eventually I hope I can get a proper Kameleon to use with my HD800's. But priorities you know. Enjoy yourself.

I think I have found the root cause of my Tinnitus. Measured both my ears (HD650, no EQ in this case) and my left ear rolls off above 8kHz where my right ear has become more sensitive in that part. The brain tries to compensate and this causes the Tinnitus.  Have been putting drops of sunflower oil in my ear for a week now as I suspect/hope some ear gunk was 'squashed' against the ear drum whilst rinsing it. Maybe that affects the highs only (I hope) Perhaps it is just my hearing gone bad though. Could hear up to 15kHz with both ears just fine about 6 months ago. Anyway.. visiting the GP on Monday. Let them check if the entire eardrum is squeeky clean or not. Today and yesterday the Tinnitus was very 'soft' and barely audible. Haven't listened to music in more than 2 weeks now and stopped the notch therapy as there were no further improvements. Hoping the ear drum is not entirely clean and that's what causes the hearing loss. If not and it remains stable this way I am going to convert one of the portable Kameleons into a hearing 'correction' device. Boosting treble in the left ear and lowering it in the good ear. That should give proper tonal balance again. |

That's interesting. One ear is different so the brain could be compensating. It would be really good if the main cause of tinnitus is something along these lines. If the hearing is damaged in one ear, I wonder whether a hearing aid in the poor ear to raise the missing bits to match the right ear would diminish the noise once the brain resets itself?

I think you are on to something. When I had an audiogram done in a sound proof chamber (a Cold War shelter) I had a 2 dB drop at 6000 Hz. All the other frequencies were at 0dB up to 8000 Hz. That's as far up as they test. I had a very very slight ringing at around 6000 Hz. (Being a semi-semi-semi-semi-not-pro musician, and lover of music I ran to my doctor right away and he sent me to the ENT doc for the audiogram).
Anyway, she even knew from the audiogram that I had been a hunter, was right handed, and shot a 20 gauge double barrel. She explained that my brain was trying to fill in for the slight loss hence the mild tinnitus. 2 dB isn't considered hearing loss but I still had the tinnitus. Hasn't changed much since then unless I am exposed to a sudden loud sound. A few years ago it started to really increase in my right ear, and my hearing was going down hill too. Ran to my GP. I had a big piece of wax that had adhered to my eardrum. Took him 3 tries with warm soapy water before it came out. It was like someone had taken out an ear plug. It took several days before the loud ringing stopped. Hoping this is what is going on with you. She also said you really can't get a completely accurate picture of your hearing without having a professional audiogram done under proper conditions. That is to say in total quiet. That chamber was absolutely quiet. If you put a dB meter in there it would read zero. Wish I had one at home sometimes.
Hope things work out well Frans. It is a frustrating thing to deal with.
