Questions people actually ask

A frequency program is a structured 4-week audio protocol that delivers precise Hz tones designed to guide your brain into a target state — deep sleep, calm, or sharp focus. Each session builds on the last. It is not music, not ambient sound, and not meditation. It is a protocol built on peer-reviewed neuroscience — the same research used in clinical sleep labs.

Brain.fm and Headspace play audio content. Tihna delivers programs. You get a 4-week structured protocol with a specific Hz target each week, session-by-session progress tracking, headphone quality verification before every session, and in-app citations linking to the peer-reviewed studies behind every frequency. No competitor combines all of this.

Sleep Program (6 Hz theta): 28 sessions over 4 weeks designed to reduce sleep onset time and improve deep sleep quality. Based on a 2024 Oxford Academic Sleep Journal study showing sleep onset of 6.1 minutes vs 12.5 minutes in the control group.

Calm Program (10 Hz alpha): 28 sessions targeting anxiety reduction and nervous system regulation. Based on alpha frequency research including a 2026 PLOS ONE RCT.

Focus Program (40 Hz gamma): 28 sessions for working memory, cognitive clarity, and sustained attention. Based on a 2025 PMC study linking 40 Hz gamma to working memory improvements.

Morning Program (18→21 Hz beta): 28 sessions for shortening sleep inertia and lifting you into the alert range — 18 Hz beta in Weeks 1–2, rising to 21 Hz in Weeks 3–4, on a 392 Hz carrier. Based on beta-range arousal research including a 2025 Frontiers in Psychology study on the delta-to-beta morning transition.

Yes — stereo headphones are required. Earbuds, in-ear, or over-ear all work. The programs deliver different tones to each ear simultaneously, which requires separate left and right audio channels. Phone speakers play mono audio and cannot produce this effect. Tihna runs a headphone check before every session so you're never left guessing.

Sessions range from 20 to 45 minutes depending on the week and program. Sleep sessions are typically done in bed as you fall asleep — you don't need to stay awake for the full duration. Focus sessions are best done while working or studying.

Yes. Daily use is part of the protocol design. Consistency is what builds the effect — each session reinforces the neural pattern from the previous one. Missing occasional sessions won't break your progress, but daily use gives the best results.

Yes. The frequencies used in Tihna — 6 Hz theta, 10 Hz alpha, 40 Hz gamma — are within the natural range of human brainwave activity. They are the same frequency ranges studied in peer-reviewed clinical trials. Tihna is a wellness tool, not a medical device. If you have a neurological condition or epilepsy, consult your doctor before use.

Most users report noticing something in the first week — falling asleep faster, feeling calmer after a session, or finding it easier to concentrate. The full protocol effect builds over 4 weeks as your brain adapts. Consistency matters far more than intensity.

You can enrol in one program at a time. We recommend completing your first 4-week program before starting a second. Most users start with Sleep, then move to Calm or Focus once they've experienced results.

The free tier includes Sleep Sessions 1–3 from the Sleep Program, and one Quick Calm session from the Calm Program. No credit card is required. The free tier never expires — use it as long as you like.

Free tier: no cost, no card.
