Get same-day medical help (urgent GP, urgent care or A&E, as you would for sudden
vision loss) if hearing goes suddenly or fast, especially in one ear: treatment that works has to start within about
72 hours.
See a GP and ask for referral if the noise is only in one ear, if it pulses in time with
your heartbeat, if it comes with dizziness, a headache, or any weakness or numbness, or if it is new and not
explained by a loud event.
What actually has evidence behind it: hearing aids if you have hearing loss (most people
with tinnitus do, and often do not know), CBT, and sound therapy — which is what this is for. No supplement, ginkgo,
or drop has been shown to silence tinnitus.
Habits that help: keep background sound at night, protect your ears at gigs and with power tools,
keep headphones near 60% and take breaks, and do not put anything smaller than your elbow in your ear.
