When you first discover that sound helps your tinnitus at night, a new question immediately replaces the old one. How long should it run? All night, or just until you fall asleep? If you set a timer, how long? And what happens if you wake up after the sound has already stopped?
These are not minor practical details. For many people with tinnitus, the difference between running sound for two hours and running it all night is the difference between a broken night and a manageable one. Getting the timing right is worth thinking through properly.
Why timing matters more than it seems
Sound therapy works by giving your auditory system something to process other than your tinnitus. When the sound stops, that competition disappears, and tinnitus moves back to the foreground. For a light sleeper, or for someone whose tinnitus tends to spike in the early hours, waking into silence can trigger a fully-alert 3 am with the ringing feeling particularly loud.
The auditory system is not fully switched off during sleep. Research on sleep-stage auditory processing shows that the brain continues to monitor its acoustic environment throughout the night, with arousal thresholds lowering during lighter sleep phases. A sudden transition from sound to silence is detectable even during sleep, and for a sensitised tinnitus nervous system, it can be enough to push you from light sleep to waking.
That is the core argument for running sound through the whole night: not just to help you fall asleep, but to protect the fragile transitions between sleep cycles that happen every 90 minutes or so.
The case for running all night
If you take one thing from this article, let it be this: for most people with tinnitus, sound therapy works better when it runs continuously through the night.
The logic is straightforward. The 3 am or 4 am wake-up is often the hardest moment with tinnitus. Your cortisol is at its daily low, your cognitive defences are down, and you have nowhere to direct your attention except the sound in your head. This is not the moment you want to discover that the background sound has turned itself off.
Running sound all night is also what allows habituation to extend into sleep. If your brain is repeatedly jolted into awareness by silence at 2 am, that pattern works against the gradual re-categorisation of tinnitus that habituation depends on. Consistent sound coverage overnight signals to the auditory system that the tinnitus is not the most salient thing in the environment — night after night, that message compounds.
Battery drain and speaker reliability are the practical objections. Both are real. A good solution is to use a dedicated device — a small Bluetooth speaker on the bedside table paired with an app set to a continuous overnight session — rather than relying on a phone set to screen-off. Overnight modes built for tinnitus are formatted to run without phone lock-screen interruptions and without draining the device trying to keep a display active.
When a timer makes sense
Not everyone needs all-night sound, and some people genuinely do better with a timer. The main cases for using one:
- You fall asleep quickly once the ringing fades, and you rarely wake in the night
- You find yourself waking specifically when the sound is still playing, as if it is keeping you in lighter sleep
- You are using earbuds rather than a speaker, in which case running sound all night is not advisable for ear canal health reasons
If any of these describes you, a timer is perfectly reasonable. The question is how long.
How long to set the timer
A common starting point is 60 to 90 minutes — roughly one full sleep cycle. The idea is to give yourself enough coverage for the most difficult part of the night (the transition from waking to sleep) while allowing the rest of the night to run without it.
The problem with 60 to 90 minutes is that it cuts out before the second sleep cycle begins, which is around 90 to 100 minutes after falling asleep. If your tinnitus tends to disturb the second or third cycle rather than only the first, a single-cycle timer leaves you exposed at exactly the wrong moment.
A more reliable approach, if you want to use a timer at all, is to extend it to three to four hours. This covers the first two full sleep cycles, which is when most people report the worst tinnitus-related disruption. By the time the sound stops, you are far enough into the night that waking into silence is less likely to produce a fully-alert 3 am spiral.
Try 90 minutes first, then extend if you find yourself waking when it stops. Adjust in 30-minute increments over a week or two rather than jumping straight to all-night.
Fade-out versus hard stop
If your app offers a fade-out option, use it. A gradual reduction over five to ten minutes is far less detectable to the sleeping brain than a hard cut. You are much less likely to register the transition, and even if you do, the audio cue is gentler and less likely to produce full waking.
A hard stop — sound at full volume, then nothing — creates exactly the kind of contrast your auditory system is primed to notice. For someone whose nervous system is already tuned to monitor for tinnitus, that contrast can become a reliable wake trigger in its own right.
If your timer offers no fade option, it is worth asking whether you would actually sleep better by running sound all night instead. A hard-stop timer may be giving you the worst of both options: sound that ends at the wrong moment and wakes you more reliably than the tinnitus itself.
What to do when you wake after the sound has stopped
It happens even with the best setup. You wake at 3 am, the room is silent, and the tinnitus feels loud. The most important thing is not to panic about the sound having stopped. Anxiety about it will make the tinnitus feel louder and harder to settle.
First step: turn the sound back on. Do not lie in silence waiting to see if you fall back to sleep. Even at low volume, reintroducing the therapeutic sound breaks the silence-to-tinnitus contrast that woke you. It gives the auditory system something to process other than itself.
Then use whatever you have for settling: calm breathing, a short body scan, deliberately loosening tension in your jaw and shoulders. Tinnitus typically feels loudest in the first few minutes of a night-time waking and quieter after ten to fifteen minutes, whether or not you do anything specific. The sound helps you get through that window.
If the pattern of waking when the sound stops happens more than once or twice a week, that is a strong signal to switch to all-night sound and remove the timer entirely.
Matching the setting to where you are in sound therapy
If you are new to sound therapy, starting with all-night continuous sound is the lower-risk choice. It removes the timer as a variable, which means one less thing to troubleshoot if sleep is still difficult. Once you have established a reliable baseline — several weeks of improved sleep — you can experiment with timers if you want to.
If you have been using sound therapy for a while and sleep is mostly manageable, the timer question becomes about optimisation rather than survival. A well-tuned four-hour timer with a fade-out will work well for many people and has the practical advantage of not relying on Bluetooth staying connected all night.
The goal is a routine that is consistent and low-friction. The best setting is the one you actually use every night, not the one that is theoretically optimal.
Finding your setting in StillWell
StillWell's sleep timer is built around these considerations. You can set a fixed duration, choose a fade-out length, or leave it on continuous for the whole night. The overnight mode is designed to avoid the common pitfall of a phone going into aggressive power-saving mode and cutting audio mid-session.
If you are unsure where to start, try this: set a four-hour timer with a five-minute fade-out. Run it for two weeks and note whether you wake when it stops. If you do, switch to continuous. If you do not, you have found a setup that works for you.
Small adjustments, tried consistently, are what move the needle. One reliable night leads to another, and the cycle that tinnitus starts — broken sleep making everything harder — starts to run in reverse.
