Five sound tools to explore

Some people find certain sounds calming. Try one, layer them, or rotate — see what works for you.

From the builder

Hi, I'm Navdeep.

I built HushOS after struggling with tinnitus, focus and sleep challenges myself.

I found that certain sound combinations personally helped me feel calmer, focus better and sleep more comfortably. After trying many expensive tools and apps, I wanted to create something simple, private and free that others could try too.

I'm not a doctor or clinician — just someone sharing something that personally helped me, and hoping to learn from real people through feedback.

How it works

Three steps. Five minutes.

  1. 1

    Match your pitch

    Slider, or the guided Higher-or-Lower flow if you prefer. Takes about a minute.

  2. 2

    Pick an approach

    Match, mask, notch, neuromod, CBT — start with whatever fits your day. Save the mix that works.

  3. 3

    Track for 30 days

    A 30-second daily check-in. See trends, print a personal summary for clinic visits.

Four guided programmes

For people who want a structure to follow, not a buffet to pick from.

During the day

Sleep is half the battle. Tinnitus eats focus too — these two tools keep your daytime steady.

What HushOS can and cannot do

Clear about what this is — and what it isn't.

HushOS can

  • Support better sleep
  • Help with sound-based relief
  • Support coping skills
  • Help you track patterns
  • Encourage daily habits

HushOS cannot

  • Cure tinnitus
  • Diagnose hearing problems
  • Replace a doctor
  • Guarantee outcomes

Inspired by published research

HushOS adapts ideas from publicly available academic work — these are starting points, not promises of clinical outcomes. Experiences vary.

  • TRT (Tinnitus Retraining Therapy) — Jastreboff & Hazell's neurophysiological model: directive counselling plus sound enrichment to habituate the brain's response.
  • Notched music therapy — Okamoto et al., PNAS 2010: listening to music with a one-octave notch around the tinnitus frequency significantly reduced loudness over twelve months.
  • Acoustic coordinated reset (CR) — Tass and colleagues: short tone sequences around the tinnitus pitch, based on the desynchronisation hypothesis of pathological neural firing.
  • CBT — Cima et al., recommended by the European and UK NICE guidelines as the first-line therapy for tinnitus-related distress.
  • Internet-CBT — Andersson, Kaldo and Beukes RCTs: structured eight-week iCBT — trial participants reported meaningful TFI drops comparable to in-person therapy, at a fraction of the cost.
  • Somatic tinnitus — Levine et al. and the TMJA literature: a substantial proportion of tinnitus can be modulated by jaw, neck or shoulder movement, and targeted physiotherapy helps.
  • Hyperacusis (sound tolerance) — Khalfa et al. (questionnaire) and Aazh / Moore (treatment): gentle, structured re-exposure with low-level pink noise improves tolerance over six to eight weeks in most people.
  • HRV / coherence breathing — McCraty et al. and Russo et al.: slow breathing at around 5.5 breaths per minute maximises heart-rate variability and shifts the autonomic balance, reducing the fight-or-flight component of tinnitus distress.

What HushOS is not

Not a cure

No tinnitus app is. HushOS helps the brain learn to ignore the ringing — over weeks, not minutes.

Not a medical device

It's a wellness tool. We don't diagnose, prescribe or replace clinical care.

Not a substitute for a doctor

If your tinnitus is sudden, one-sided, pulsatile, or paired with hearing loss or dizziness — see a doctor first.

Not magic

The approaches work because you show up daily. Eight to twelve weeks is realistic.

Not a guarantee of outcomes

Tinnitus is highly individual. We share what helped trial participants — not a promise about what will help you.
