Editorial Standards
Our Editorial Mission
Restful Night Studios covers sound therapy, sleep audio, and acoustic wellness—a space where enthusiastic claims often outpace the research. Our editorial mission is the opposite: we report what the peer-reviewed evidence actually shows, including its limits.
Every guide on this site is written to a single standard: a reader should finish it knowing exactly what the science supports, what remains preliminary, and what is traditional belief without strong clinical backing. We label all three explicitly on every page.
How We Select Sources
We source claims from peer-reviewed research indexed in PubMed and the Cochrane Library. We apply these minimum thresholds:
- Randomized controlled trials: preferred for efficacy claims
- Meta-analyses: cited when available and methodologically sound
- Minimum sample size: we note when studies have fewer than 30 participants and treat findings as preliminary
- Publication date: we prioritize studies from the last 10 years; older foundational studies (e.g., Oster 1973) are cited for historical context only
- Replication: single-study findings are labeled “Preliminary Evidence” regardless of effect size
- Retracted studies: we maintain a do-not-cite list and remove references when retractions are identified
We do not cite press releases, manufacturer claims, or studies funded exclusively by parties with a direct commercial interest in the outcome without disclosing the conflict.
Our Evidence Tier System
Every factual claim on Restful Night Studios is tagged with one of three evidence levels:
Multiple peer-reviewed studies with consistent findings and adequate sample sizes. Effect sizes are reported where available.
Example: Theta-range binaural beats for anxiety reduction (Garcia-Argibay et al., 2019 meta-analysis, g = 0.45).
Findings from one or a small number of studies, often with small samples or methodological limitations. Promising but not yet established.
Example: Beta-range beats for cognitive performance.
Widely reported in practitioner communities with limited or no peer-reviewed clinical evidence. We include these claims for completeness while being explicit about the evidence gap.
Example: Gamma-range beats for learning enhancement.
Our Review Process
Content is produced through a structured pipeline:
Research phase
Primary literature review against PubMed and Cochrane. Claims are mapped to specific studies with DOIs.
Draft phase
Content is written against a fact-check template that flags unsupported claims, overclaims, and missing citations before publication.
Editorial review
Each page is reviewed against our evidence tier standards. Claims that cannot be assigned a tier are removed.
Citation audit
All references are verified for correct DOI resolution, non-retracted status, and accurate representation of findings. We do not overstate effect sizes or generalize beyond the study population.
Update policy
Pages are reviewed when new meta-analyses or systematic reviews are published in our coverage areas. The “Last updated” date on each page reflects the most recent content or citation review.
What We Cover and Don’t Cover
We cover
- The peer-reviewed science of binaural beats, sound therapy, and acoustic wellness
- Practical guidance for using audio tools safely and effectively
- Honest comparison of audio approaches with explicit evidence-level labeling
We do not
- Provide medical advice or diagnose conditions
- Recommend discontinuing or modifying prescribed treatments
- Make efficacy claims beyond what the cited research supports
Sound therapy content is for informational and wellness purposes. It is not a substitute for professional medical care. If you have a diagnosed sleep disorder, anxiety disorder, or other medical condition, consult a qualified healthcare provider.
Corrections Policy
We correct factual errors promptly. If you identify an error—an outdated citation or retracted study, a misrepresented research finding, or a factual claim without adequate support—we want to know.
Contact us at editorial@restfulnightstudios.com. We will review and correct within 5 business days. Significant corrections are noted at the bottom of the affected page.
Affiliate and Commercial Disclosure
Some pages contain affiliate links to products we recommend. Affiliate relationships do not influence our editorial assessments. Products are recommended based on their fit for the use case described, not on commission rates.
