Optimized Active Noise Cancellation for Hearing Tests Using Auditory Masking Characteristics.
Article in IEEE journal of translational engineering in health and medicine, 2025. 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
objectiveEnvironmental noise poses a major barrier to the accuracy of self-administered hearing tests conducted outside clinical settings. There is a pressing need for effective noise control solutions to enable reliable hearing threshold measurements in everyday environments. This study introduces an optimized active noise cancellation (ANC) technique based on auditory masking characteristics.
methodThe method was implemented in a mobile hearing test system using calibrated true wireless Bluetooth earphones. Electroacoustic validation and clinical testing were conducted across four ANC scenarios: normal, generic ANC off, generic ANC on, and optimized ANC on in 65 dB(A) pink noise.
resultsA total of 50 participants completed hearing tests at eight frequencies (0.25-8 kHz), and results were compared to standard audiometry. The optimized ANC yielded the highest signal-to-noise ratio in noisy conditions and demonstrated strong agreement with standard hearing thresholds (r = 0.99, p <.01) in normal environments. Under 65 dB(A) noise, the proposed method significantly outperformed generic ANC with smaller hearing measurement error, improving threshold accuracy across most frequencies.
conclusionThe proposed ANC technique enhances hearing test reliability in noisy conditions, supporting accurate, self-administered hearing assessments outside clinical settings. This technology has strong potential for home or community-based hearing healthcare applications.
