I was dumb enough to watch Mad Max in 4K Blu-ray in my enclosed home theater using my Nakamichi Dragon with four 12" subwoofers at 50% volume.
The result was that by the end of this 117 dBA peak-generating movie (132 dBC), my hearing was muffled in my left ear, and I could hear a faint ringing.
Two days went by, and I didn't pay much attention. I've always been a bass head who loves loud music, so I thought it would eventually go away. But after three days, the ringing became louder.
Naturally, I went to ENTs, audiologists, and ear, nose, and throat doctors. None of them had much to offer except Prednisone, a steroid nasal spray, and the clear statement that the ringing was here to stay—forever.
I started researching like crazy and stumbled upon Tinnitus Talk. I read countless threads, and one thing kept coming up: NAC (N-Acetyl-L-Cysteine).
At that point, I had been taking Prednisone for two days. My doctor then switched me to Dexamethasone IM after I told him I had read that Dexamethasone was superior for noise-induced hearing loss, with fewer side effects such as hydrops. He agreed, and I swapped to 10 mg of Dexamethasone IM for the rest of the seven-day course.
I could swear the Prednisone made my tinnitus worse, although my hearing seemed to improve in both my muffled ear and my good ear. The same happened with Dexamethasone, but without the increase in tinnitus.
Side note: I had never experienced tinnitus before this initial event.
Fast forward to fifteen days after this terrible experience, I developed hyperacusis. Any sound that had previously been pleasant or comfortable (80 to 90 dBA) now triggered the worst tinnitus imaginable later that night, and it made my ears feel muffled.
Desperate, I started taking Jarrow's NAC Extended Release. At first, I felt some relief in my hearing, and by day five of taking NAC (day twenty since the event), I could swear my hearing was the best it had been since it all started.
Sadly, that didn't last long. Just three days after that improvement, I experienced the worst tinnitus imaginable. It came rushing in fast and hard, and coincidentally, this happened right after I switched from Jarrow's ER formula to Thorne's IR 500 mg capsules.
That's when I realized I was getting worse, and I believe NAC had everything to do with it.
How could something that made me feel better for five days suddenly make my tinnitus worse?
The main problem was that I had somewhat habituated to my 1,500 Hz tinnitus, but after taking NAC, a completely new, more intrusive high-frequency tone appeared, and it was hell.
I even started to miss my previous 1,500 Hz tinnitus, which was drowned out by the new 7,500 Hz tone.
For the first time, I needed masking sounds like violet noise. Unfortunately, when I woke up the next morning, the same violet noise that had helped me sleep made my ear feel muffled. This only happened in the ear facing the sound, which was playing at just 5–10% of my phone's volume on the nightstand next to me. I stopped masking after that.
It's been two weeks since I stopped taking NAC and around five weeks since the regretful Mad Max event. I've now started taking Nicotinamide Riboside, Resveratrol, Acetyl-L-Carnitine, ALCAR, and NMN. But I can say with confidence that the high-frequency tinnitus that NAC apparently caused has not gone away as I'd hoped. I'm afraid it may become chronic, which would really be awful.
I'm posting this as a cautionary story for anyone considering NAC because of all the reported success cases. Maybe the dosage or the timing had something to do with it (the first five days seemed great), or maybe it was the switch from Jarrow's to Thorne.
Just be careful. There's still so much we don't know about these supplements, tinnitus, and hearing loss. Why did NAC cause me to develop a high-frequency tinnitus tone? I don't know. What I do know is that I'm done with NAC.
TL;DR: NAC gave me new high-frequency tinnitus tones. My tinnitus bother level went from 4 to 8, and it hasn't improved after two weeks of stopping NAC.
