Heat Pump Noise: Scoping Overview of Emission Characteristics and Systematic Review of Human Effects.
Synthesis in Noise & health. 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
objectiveThe aim of this work is two-fold: to characterize air-source heat pump (ASHP) noise emissions and to systematically evaluate the scientific evidence regarding non-auditory health effects, thereby assessing the technology's current and future public health impact.
methodsThe primary component is a PRISMA-guided systematic review on noise impact. Utilizing a population-exposure-outcome framework, eight bibliographic databases were searched for English and German records. Of 501 identified records, 26 reports (covering 25 unique studies) met eligibility criteria. Risk of bias (RoB) was evaluated across four domains-sampling, measurement validity, confounding, and reporting-while overall evidence certainty was assessed using established frameworks. A secondary, non-systematic scoping overview was conducted to characterize ASHP noise emissions based on technical databases and literature.
resultsASHP sound emissions are highly variable, contingent upon specific components (fan and compressor), radiation angles, and operating conditions. The systematic review identified 10 laboratory studies, 14 observational surveys, and one prognosis study, predominantly published since 2011. While results indicate a non-negligible potential for annoyance, concentration impairment, and self-reported sleep disturbance, the overall certainty is low. This is attributed to small samples, methodological heterogeneity, and high RoB in critical domains. Preliminary data provide tentative indications that ASHP noise may exhibit higher annoyance potential than road traffic noise at equivalent sound pressure levels.
conclusionDespite increasing research interest, the evidence base for long-term health impacts of heat pump noise remains limited and of low certainty. Future research should prioritize large-scale longitudinal studies and comparative investigations with other environmental noise sources to inform evidence-based noise control.
