1 · What the graph read from it

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.

2 · The registry

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

This article explores acoustic band gap in the Thue-Morse phononic crystal structures for application in acoustic filtering. By using the unique nature of Thue-Morse sequences, we systematically analyze transmission spectra over many generations of structures using the transfer matrix and finite element methods. The proposed generalized Thue-Morse is constructed by alternating blocks based on two resonator sequences. The first sequence consists of parallel open resonators while the second block has an open resonator. The results show that acoustic band gaps can be widened and fragmented by adjusting resonator coupling strength and structural complexity. Higher-order resonances and localized modes enable the formation of sub-gaps in the frequency-selective response. These findings highlight the potential of Thue-Morse phononic crystals for precise acoustic filtering and wave manipulation in advanced material applications.
