Editorial standards
How the guides on this blog are written, sourced and kept up to date, so you can judge how far to trust them.

Who writes the articles
The articles are written by Michal Piják, founder of noctune. He is an independent developer, not a doctor, audiologist or sleep scientist, and the articles are not reviewed by a medical professional. They are general information, not medical advice. Where a topic touches health (hearing, tinnitus, babies, ADHD), the article says so at the top and tells you when to see a professional.
Noctune is our own app. Articles mention it at most a few times, only where it is relevant, and never claim that it treats or prevents anything.
How we choose sources
- We prefer systematic reviews, clinical guidelines and official health bodies (for example WHO, NICE, NHS, NIDCD and the American Academy of Pediatrics) over single studies, and single studies over news coverage.
- Every factual claim about research is checked against the original paper or its abstract (usually on PubMed), not against another article's summary of it. When we rely on a secondary summary for a number, the source line says so.
- We describe what a study actually measured: who took part, how many people, how long, and what it did not test.
- Every article ends with a list of its sources as plain links, so you can check them yourself.
- When we can't find a source for a popular claim, we say that instead of repeating it.
How we rate evidence
Articles that discuss research have a "What the research says" box. Each main claim gets one of four labels:
- Strong evidence: consistent findings from good-quality studies or measurements, or a clear recommendation from an official guideline.
- Moderate evidence: a systematic review rated its own certainty as moderate, or the findings are consistent but the effect is small or the setting narrow.
- Limited evidence: few, small or low-quality studies, mixed results, or reviews that rate the evidence as low or very low.
- No direct evidence: nobody has tested the claim directly. It may still be plausible, but it is an idea, not a finding.
The labels are our editorial judgment based on the sources listed in the article, not a formal grading.
Illustrations, diagrams and sound samples
The article illustrations are made with AI image tools, then chosen and cropped by us, in the same night style as the app. They are marked "Illustration: Noctune (AI-assisted)". They set the mood or show a setup (for example, where to put a speaker); they never show real people, products or medical scenes, and they are not evidence for anything.
Diagrams are drawn by us from the numbers in the cited sources, and each one names its source below it. The sound samples are the same recordings and noise generators the app uses.
Corrections and updates
Each article shows its publication date, and an "Updated" date when we change something of substance, such as new research or a corrected number. If you find a mistake, write to support@noctune.app; we read every message and fix errors.
