Tinnitus Explained

An article by Rachel Levy, hearing aid specialist — Audition Solution, Ville Saint-Laurent.

A ringing that no one else hears, a hiss that fills the silence: tinnitus intrigues as much as it exhausts. Understanding where it comes from is already the first step toward relief.

Where does this sound no one else hears come from?

In the vast majority of cases, tinnitus is the auditory system's response to a lack of input: when certain frequencies stop arriving (age, noise, earwax plug), the brain turns up its “internal gain” and ends up generating a phantom sound. That's why tinnitus so often goes hand in hand with hearing loss — sometimes one so slight it went unnoticed.

Why is it worse at night?

During the day, ambient sounds partially mask the tinnitus and your attention is occupied. At night, silence removes any competition: the brain has nothing left to listen to but its own signal. Fatigue and stress — which increase the nervous system's vigilance — complete the vicious circle.

What actually works

  • Treating the hearing loss: when hearing aids restore the missing frequencies, tinnitus usually fades into the background — it's the most effective single measure.
  • Sound enrichment: soft background noise (fan, dedicated apps, built-in programs in hearing aids) removes the silence that makes tinnitus scream.
  • Habituation (TRT): teaching the brain to classify tinnitus as neutral, like a clock's ticking, until it filters it out on its own.
  • Managing stress and sleep: relaxation, exercise, regular sleep schedule — everything that calms the nervous system calms the tinnitus.

When to see a doctor promptly?

Sudden tinnitus, one-sided tinnitus, tinnitus pulsing with your heartbeat, or tinnitus accompanied by dizziness or a rapid drop in hearing deserve a medical consultation without delay.
