Abstract

This study aimed to develop sound resonance measuring tools for an Android-based Sound Level Meter as an innovation in physics experimental tools in learning. This tool is designed to facilitate students' understanding of sound waves and sound resonance through interactive experiments. The resonance tube is the main component combined with the SLM Android microphone, sound system, wireless probe, and audio generator. This study evaluates the feasibility of the device through practical trials, which involve measuring the frequency and intensity of sound in a resonant tube. Practicum results data show that there is a significant increase in sound intensity along with an increase in frequency. This is consistent with the theory that frequency and intensity are directly proportional. However, the measurement results are also affected by factors such as the cross-sectional area of the resonant tube, the amplitude, and the material used. Based on this feasibility test, the SLM Android-based sound resonance tube measuring instrument was declared ready to be used in school physics learning. Thus, the SLM Android-based resonant tube measuring instrument is expected to increase the effectiveness of physics learning and provide a more exciting learning experience for students at school. © 2024 Author(s).
