The Bionics Institute Claim They Have Found a Way of Objectively Measuring Tinnitus

[Nick47]

I wonder if this opens up further avenues to measure "reactive tinnitus"?

@UKBloke, I've considered this many times. If a patient brought in an instrument, like a fan or kettle, that exacerbates their tinnitus, we could record their baseline and aggravated states. Similar to a cochlear implant, the patient would serve as their own control.

However, then I wondered—how can we be sure that changes in brain responses aren't just due to sound processing, rather than truly representing tinnitus activity?

Here is a simplified write up of the findings.

This is what @DebInAustralia alluded to in January of this year.

Thank you, @Nick47, for the optimistic note today. As I've mentioned in earlier posts, this could be the major contribution—our generation's big step forward, or rather, our era's step forward—in cracking the mystery and, hopefully, eventually delivering a cure for tinnitus, hyperacusis, and maybe even deafness.

Getting a bit philosophical here: I noticed back in university that when you can't solve an intractable problem, you tend to change the question a bit. In this case, while we can't stop the ringing, how can we measure it? How can we prove or detect that it's there… subjectively? Or should I say objectively?

Before the Bionics Institute got started, "subjectively" might have been the only way to describe it. But now, with their success, it's becoming more objective.

Ah, my ongoing struggles with the English language!

It might depend on how they/we define sound processing. I mean, hearing with or without tinnitus is all sound processing to a degree, just "normal" or "abnormal" processing.

If they're measuring tinnitus "severity," then going off what I personally experience with reactivity, I'd expect to see a spike in the severity metric after exposure to problematic sounds/frequencies. I think, for now at least, I could overlook the "processing" question.

In the longer term, perhaps the answer lies in a longitudinal study, although that would be pretty crap for the patient as the expectation would be for their condition to worsen in order for us to retrieve the data we want. Maybe an independent control subject without tinnitus could be useful?

I must confess that I don't see the difficulty here. I see that you (Tinnitus Onset 1991) are one "year" older than me.

The folks in white coats would simply measure the initial tinnitus loudness at onset, and then, as the years go by, take new readings to track its progress.

No need to worry! If the tinnitus is chronic, it won't go away.

Yeah, it's been a long haul!

Good work, @DebInAustralia.

Get the questions in then...

That's what happened when I got tested there. You wear earphones, and they play a sound like the ocean, which then goes silent. I was amazed at how much louder my tinnitus was right after the sound stopped. Then, it gradually died down until the next sound played.

The thought occurred to me the other day:

We know that there seem to be several types of tinnitus. There are different responses among tinnitus sufferers to the same treatment: some improve, some get worse, and some are even cured.

Once the Bionics Institute puts its machinery on the market and it becomes available in audiology departments or ENT clinics, imagine this scenario: Patient A goes in for an examination, and the printout from the machine reads:

• Tinnitus: detected
• Volume: 10 decibels at the 6,000 kHz frequency
• Source of Tinnitus: 5 cm northwest of the dorsal cochlear nucleus

With this data, ENTs and audiologists would be able to build a knowledge base on which therapy or pharmaceutical option might best alleviate that specific type of tinnitus. I didn't say "cure"—that would be too optimistic, but it's not beyond imagination.

For instance, Patient B's brain scan might show significant activity in the area connected to the nerve in the jaw, indicating a potential case of TMJ. The quest for a single, one-size-fits-all pharmaceutical cure for tinnitus (such as Lidocaine) could then become more of an academic pursuit, perhaps reserved for further study and future research.

The introduction of the Bionics Institute device could bring tinnitus relief to the forefront, allowing for customized, personalized treatments for each patient.

A step forward? I suppose I'll believe it when I see it, as the saying goes.

I don't think it pinpoints the location of the tinnitus; it only indicates whether it's present and if it's mild or severe.

They play a low sound that completely masks the tinnitus. Then, they turn it off, allowing you to hear your tinnitus in full detail. Over time, you get used to it, and it no longer seems like such a big deal.

It's similar to going to the beach and then getting into a car. On the beach, you hear the low, steady sound of the waves, which drowns out your tinnitus. But when you get back into the car, an almost airtight space, that background noise disappears, and you hear your tinnitus at full intensity.

Oh dear! If that fell into the wrong hands—like those of governments or even non-government groups...
