The effect of white noise on pain levels in newborns: a meta-analysis study.
Synthesis in Irish journal of medical science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhite noise may reduce pain levels in newborns.
aimsExamine the effect of white noise on pain levels in newborns.
methodsThe studies included in this meta-analysis were identified through a comprehensive search of databases including Web of Science, PubMed, EBSCO host, Google Scholar, and the National Thesis Center of the Turkish Council of Higher Education. Following an evaluation of the studies, 14 eligible studies were included in the analysis. The quality of the included studies was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools, tailored to each study design. Data synthesis was conducted using Comprehensive Meta-Analysis (CMA) version 2. The findings were structured through a combination of meta-analytic and narrative synthesis approaches.
resultsThis meta-analysis found that the use of white noise during painful procedures significantly reduced pain levels in newborns (SMD: -1.026, 95% CI: -1.443 to -0.610; Z = -4.828, p = 0.000). Subgroup analyses revealed that specific sounds, including those from the Colic album by Orhan Osman (e.g., "Colic," "Don't Let Your Baby Cry," "Don't Let Your Baby Cry Pt-3"), as well as intrauterine-like sounds such as hair dryers and vacuum cleaners and recordings of heartbeat sounds, were significantly more effective than other types of white noise.
conclusionsThe findings of this meta-analysis indicate that white noise is an effective intervention strategy for reducing pain levels in newborns. It is recommended that healthcare professionals incorporate white noise, which is a simple, low-cost, effective, and safe non-pharmacological method, into their clinical practice to alleviate neonatal pain.
