If your audiogram shows hearing loss — especially a high-frequency dip, which is where most tinnitus lives — then yes, hearing aids are probably the single most effective intervention available, and the most undersold. Several reviews put the rate of meaningful tinnitus improvement after fitting at around two thirds.
The reason fits the central-gain model exactly. Tinnitus is in large part your auditory cortex turning up its internal volume to compensate for missing input. Hearing aids restore that input. The cortex has less reason to keep its gain cranked up, and the phantom signal softens. Many modern aids also include a built-in masker that plays a low background sound through the receiver, layered on top of amplified ambient sound.
Hearing aids are smaller and more discreet than most people expect. They are not a sign of giving up — they are usually first-line treatment. If you have hearing loss, the question is not whether to try them, it is whether to try them now or after another few years of unnecessary suffering.
If your hearing test is genuinely flat, aids are not the route, and the standard sound-therapy plus CBT path applies.
