Troubleshooting the Internal Feedback Loop: My Tracking Notes on Magnesium and the Noise Floor

Six weeks. That's how long I went without a drop of caffeine — no coffee, no cola, not even the decaf that still has a trace of it — chasing a theory that caffeine was overdriving my tinnitus and burying any real signal from the magnesium supplements I'd already started logging as part of my ongoing tinnitus tracking. At the end of those six weeks I pulled my notes and lined them up against the six weeks before. Same severity ratings, same rough nights, same 15kHz tone sitting exactly where it always sits in the mix. Zero correlation, as far as I could tell — which, if you've ever run a controlled test at your actual day job only to get a flat, useless graph, you already know is its own special kind of anticlimactic. As an audio technician who apparently never thought to protect his own hearing health until it was too late, I've gotten used to my experiments not going the way I expect.

A friend of mine homebrews IPAs out of a converted garage setup, and he keeps a log for every batch — water chemistry, hop schedule, fermentation temperature — because if something comes out wrong, he needs to know which variable actually moved. That's close to what my tinnitus tracking looks like these days, except instead of hops I'm logging ringing severity, sleep notes, and whatever supplement is currently in rotation. Years of making sure a vocal track never clipped at 0 dBFS taught me the same instinct — you don't wait for the meter to bury itself in the red before you start troubleshooting, you catch the drift early. I just never thought to point that instinct at my own ears until there wasn't much choice left.

Magnesium Earned a Permanent Spot in My Testing Log

Magnesium supplements kept showing up in forum threads about hearing health and tinnitus, usually described in vague terms — something about calming an overactive nervous system, something about glutamate and how the two might interact, though I don't fully understand the neurochemistry and I'm not going to pretend otherwise. I'm an audio technician, not a biologist. What I can actually tell you is what happened once I started tracking it night over night instead of just swallowing a capsule and hoping.

I'm not a doctor, an audiologist, or any kind of medical professional — just a guy with a tone stuck in his ears and a notebook full of numbers he made up himself. Before anyone tries anything here, talk to an actual doctor or audiologist first; nothing in this log is a substitute for that conversation. What I did was stick to a magnesium regimen that stayed inside the general recommended range for someone my age — I'm not going to quote you a milligram figure here, it's easy enough to look up on your own — and I logged the same three things every night: how loud the ringing felt on a scale I invented, how the sharper daytime sounds hit me, and how long it took to fall asleep.

What Changed Around Week Eight

Around week eight of logging, the pattern in my notes started to look different, though it took me a while to actually notice, because nothing about it was dramatic. There was no single night where the ringing switched off like a fader pulled to zero. It was smaller than that. I remember sitting in the driveway one evening, engine just switched off, waiting out of habit for that half-second brace before the tone rushes into a suddenly quiet cabin. It didn't come. I sat there a beat longer than I needed to, just checking. That not-bracing is what showed up as a pattern in the log around week eight — not one dramatic entry, just several nights in a row where I'd forgotten to flinch.

The sharper daytime sounds changed in a smaller way too. A chair leg scraping across the floor, a car alarm chirping down the street — that kind of thing used to hit like a spike jammed straight into the mix with no limiter and no warning. It still registers. It just doesn't slam the way it used to. I'm not going to walk you through a mechanism for why, because I don't fully trust my own theories on that front — I just know what the log says, night after night, page after page, usually written at whatever hour the house has gone quiet enough that the scratch of a pen on paper is the loudest thing competing with the ring.

Does Cutting Caffeine Actually Help? My Log Says No

That's what makes the caffeine experiment worth mentioning instead of quietly burying it. I expected cutting caffeine to be the bigger lever — it's the variable everyone online swears by — and it produced nothing I could measure over six full weeks. Meanwhile magnesium, taken consistently and without me cutting anything else out of my routine, is the one variable that actually tracked alongside a change in my notes. That doesn't prove causation. It's one guy's log, not a clinical study, and a correlation in a personal notebook isn't evidence anyone else should build a decision around. But it's the most honest answer I've got after months of running this.

Figuring out exactly what triggers a spike on any given night is its own separate rabbit hole I'm not getting into here. I'll also admit I didn't run a clean washout between supplements before starting the magnesium log, which probably muddies the caffeine comparison more than I'd like it to.

A Faulty Ground Wire, Not a Cure

None of this fixes the underlying damage. Years of standing too close to monitors and line arrays did what they did, and no supplement rewires a cochlea. What magnesium seems to affect, at least in my case, is how loudly my nervous system reacts to a signal that's already there — less like replacing a broken component and more like finding the frayed ground wire that was adding hum to an otherwise decent chain. The tone is still sitting in the mix. It's just not fighting for the lead vocal anymore.

I've got a running list of things that did nothing measurable — zinc, ginkgo, a handful of others — that I've started calling the supplement graveyard, and magnesium is the rare entry that earned a permanent spot on the log instead of getting crossed off after a month. There's also a longer three-month log I kept around the same stretch, if you want to see how this all lines up over a longer timeline.

Log One Variable at a Time

If you're going to test a supplement against tinnitus, change one thing at a time and give it longer than you think you need before deciding it failed. I nearly wrote off magnesium after the first month because nothing dramatic happened, and the only reason I caught the week-eight shift at all is that I kept logging through the boring stretch instead of closing the notebook. That's the real lesson here, more than magnesium itself: the variable that looks boring for six or seven weeks straight is sometimes the one quietly doing something underneath, and you won't know unless the log is still running when it finally shows up.

There's a separate log entry on focus and the mental side of dealing with a tone that won't quit if that angle fits your situation better than the magnesium side of things — I keep the two experiments separate on purpose, one variable at a time, same as everything else here.

Anyone still working around live sound or loud AV gigs right now, with ears that still work fine: wear the plugs. I spent enough nights wandering the green room corridor at Ryman Auditorium without a single earplug in reach, let alone in my ears, to know exactly how I ended up keeping this log in the first place. Everything since then is just troubleshooting the result.
