A professor at West Texas A&M University may have discovered a way to help permanently decrease or remove tinnitus, a condition that causes a constant, and often irritating, ringing in the ears.
The American Tinnitus Association reports that tinnitus affects up to 50 million Americans. The causes of the condition vary but include hearing loss, exposure to loud noises, serious illnesses and consumption of substances such as nicotine, caffeine and medicine.
Leslie Dalton, a professor at WT's speech and hearing clinic, has spent the past 12 years developing tinnitus treatment mostly delivered through the use of a chip, software and large headphones. The chip sends a quiet and pre-programmed sound to the headphones, changing the channels sound takes to reach the brain.
Dalton, in his third year at WT, likens the process to reorganizing roads to change the way a vehicle reaches a destination. Whatever conditions lead to tinnitus affect the brain's normal functions, causing the ringing sound, he said.
"It causes the brain to reprocess in the wrong place," he said. "We return the hearing so that the normal part of the brain takes over."
Dalton has seen some success with his work.
Gretchen Mercer, who took Dalton's treatment a few times during the past year, said the method completely removed her tinnitus whenever she put on the headphones.
"The first time I put on the headphones, my whole body just relaxed," she said. "You hear nothing. It totally erases the tinnitus."
One of the goals with the tinnitus research is to create a prototype that can be distributed to local audiology clinics before the end of the summer, said Paige Brittain, owner of Headsets Inc., an Amarillo business that sells aviation and military headsets.
About a year ago, Brittain and Dalton helped start up another company, Dichonics Inc., with plans to later manufacture personal devices that can deliver the sound treatment.
"We will continue to improve the product," Brittain said. "But right now, we're just trying to put it together and put it in the hands of specialists."
While the treatment Dalton performs at WT provides no long-term fix for tinnitus, he said he thinks that giving patients daily access to a device at home would let them train their brains into ignoring the condition.
"Once we get to nano-technology, we can turn into a kind of hearing aid," he said.
While millions of Americans suffer from tinnitus, many more do not report the condition, said Diana Wise-McPherson, an Amarillo audiologist. She said most of her patients suffer from the condition.
"From past numbers I've heard, about half of the world's population has some kind of head noise," she said. "Now whether it bothers their life, that's another thing."
Treatments to relieve tinnitus exist, but none of them decrease or remove the condition, she said. Existing treatments include acupuncture and massage therapy, she said.
"People do all kinds of things, but there's nothing scientifically proven on the market that alleviates tinnitus," she said.
Other treatments include masking the tinnitus with other sounds or sending electricity into the ear's cochlea, Dalton said.
"But the patient still hears something," he said.
Mercer said she developed tinnitus about two years after contracting the West Nile virus in 2004. The virus caused some hearing loss, she said.
"In my experience, it can debilitating," she said. "It can drive you insane. It's a constant humming in your head. Sometimes, you can ignore it, but there are times when it's just loud and it gets worse."
Your cousin and Dick Cheney on a hunting trip would be an interesting day...............
Sometimes the ringing in my ears is so bad I can hardly hear the little voices in my head.
Who knows, if it doesn’t help the tinnitus, at least your ears will look younger!.............
That may be because it’s not FDA approved yet...........
I have had this as long as I can remember. I have had none of the things listed as possible triggers. We used to live near a major highway and it sounded like a big truck coming but I noticed that the truck never passed on by. LOL! I use a little sound making device at night that is louder than the ear noise and that blots it out.
***10 years of Fender and Mesa Boogie amps turned to 11 has left me with ringing ears.***
For me it was ..
4 years of B-52s and KC-135s.
8 years of steel fabrication shop noise.
31 years of Power Plant noise of which 21 years with blood anti-coagulants.
And I wore ear plugs!

A few shots of bourbon help! but then I’m seeing double.

That could be your problem..............

I attribute mine to a combination of many years of copying morse code through headsets AND in 1962 my sinuses ‘blew up’ in the Submarine School Escape Tank.
The ringing gradually got worse and for years I was able to ‘white it out’ but as I get older, it gets harder (whiting out) and I swear it is so loud people standing next to me should be hearing it.
Also, when I talk, I feel like I am ‘screaming’ so to compensate I tend to talk to ‘low’ so people naturally think because I am getting ‘old(er)’ I can’t express myself properly.
That is just as frustrating as the ringing...
VA not much help here either, though I haven’t really pushed it as I believe there are people out there with ‘real problems’.
Interesting, I’ve never heard that aspirin causes tinnitus...when I was trying to get pregnant in the late 90s and 00s, I started taking low dose aspirin daily, and it HELPED reduce the tinnitus for me, at times when I stopped taking it, the roaring and loudness returned...I started taking it again a few years ago for my twin pregnancy and it was reduced, have kept on taking it for heart/stroke prevention. Had a heart workeup done a month ago, and they said my arteries etc. are beautiful and clear, so something is helping! :-) They also credited my taking fish oil capsules for helping with clean arteries and lower cholesterol levels (especially triglycerides).
I’ve never been diagnosed with high blood pressure. Although my blood pressure is screw these days. It’s usually never high and when it is it never lasts very long.
My little thingy makes the sounds of waves on the shore, or waterfalls, or rain on the roof. Not quite the same as yours.:D
Thanks for the ping. Maybe this technique can be built into regular hearing aids.
