The longer, the better? Investigating the effect of prolonged acoustic stimulation on brief acoustic tinnitus suppression.
Trial report in BMC neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07472257 (Effects of Acoustic Stimulation Techniques on Tinnitus), which is not on this 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.

Abstract
backgroundBrief acoustic tinnitus suppression following sound stimulation is being studied to better understand the mechanisms underlying tinnitus and short-term suppression of the tinnitus perception. In this context, several kinds of filtered or modulated stimuli have been investigated. However, little research was conducted regarding the effect of stimulation length for brief acoustic tinnitus suppression.
methodsThe aim of the present study was to compare the extent of tinnitus suppression after a 20-minute and a 3-minute acoustic stimulation with an individual best stimulus. Three experimental sessions were completed by 33 participants with chronic subjective tinnitus. In the first two sessions, eight different individualized, filtered, and/or amplitude-modulated stimuli were presented for 3 min each. For each participant, the stimulus which induced the strongest tinnitus loudness suppression (measured with a numeric rating scale in percent compared to baseline loudness) was chosen and then applied for 20 min in a third session.
resultsOn a group level, no significant difference in tinnitus loudness suppression comparing the 3-minute and the 20-minute acoustic stimulation using the individual best stimulus was observed. However, individual response patterns revealed great diversity as 12 participants showed better suppression after the 20-minute stimulation,12 experienced worse tinnitus suppression and for 9 participants no distinct change was evident compared to 3-minute acoustic stimulation.
conclusionsFuture research should try to characterize the subgroup of tinnitus patients that profits from prolonged acoustic stimulation and search for optimized simulation durations.
