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

The automotive industry is moving towards low noise and lightweight, and acoustic metamaterials can play a vital role. This paper presents a new acoustic metamaterial consisting of cylindrical holes of different depths arranged circumferentially and divided into different cavities by spacers. The goal is to improve the acoustic absorption performance at low and medium frequencies (f ≤ 1100 Hz). The structure was simulated and studied using the finite element (FEM) simulation software COMSOL Multiphysics to analyze the noise reduction mechanism. Simulation analysis showed that the average sound absorption coefficient is greater than 0.90 in the 510 to 970 Hz frequency range. The acoustic absorption performance of the acoustic metamaterial designed in this paper is verified by using 3D printing to produce a model and an experimental study based on impedance tubes, and the FEM simulation and experimental curves are in good agreement.
