Methodology Development and Performance Testing of an Acoustically Isolated Booth Using the Iso 23351-1:2020 Standard

Abstract

An acoustically isolated meeting booth is a specially designed structure used to isolate and reduce the level of speech. This pod is made in order to create a sound-isolated space, where you can work, record or perform sound in conditions of minimal noise and interference. Acoustically isolated pods are used for various applications such as music recording studios, movie theaters, conference rooms, and wherever it is important to limit sound transmission and ensure a quality acoustic environment. In this type of acoustically isolated rooms, acoustic characterization of all types of sound sources, as well as sound receivers, usually sound sensors, is carried out. The main objective of this research is to develop a methodology using the ISO 23351-1:2020 standard and test the performance of an acoustically isolated cabin. In addition to the primary goal of research, an additional goal is the analysis of the accuracy of the results obtained from a low-cost noise sensor through its comparison with a class 1 sound meter. The obtained results provide an opportunity for research and application of standardization that enables the development of a methodology for measurement and assessment of the characteristics of an acoustically isolated booth. In particular, the focus is on applying the methodology, measuring and comparing the results of noise measurements between a class 1 sound meter and a low-cost sensor unit.
