“…To implement this, several factors are taken into account, such as materials, construction, and sound transmission reduction [22]. When designing an effective acoustically isolated cabin, the following characteristics need to be considered: the chosen suitable acoustic materials should have good sound absorption and sound blocking properties, the room or object design with double or triple walls, floors, or roofs with air gaps between them should increase the space for sound isolation, and the use of acoustic materials that absorb sound would help reduce sound reflection in the space [23]. To achieve improved sound absorption, acoustic absorbers are of great importance.…”

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.

Objective The aim of the study is to develop new acoustic materials and panels that high sound transmission loss (STL), low carbon emissions, high sensitivity to human health, and also do not harm the indoor air quality. These materials are currently grown in Turkey and can be easily adopted in the industry. It has been comparatively analyzed that the developed materials can be alternatives to the synthetic materials on the market. Methods In the experiment box similar to Alpha Cabin, which was designed and developed before, the STL values were obtained by conducting experiments in the frequency range 500–8000 Hz. with many natural and synthetic materials. In the study, low carbon emission natural materials with a STL of more than 30 dB were selected. Simulation The experimentally measured samples were simulated in the acoustic module of the ANSYS program and compared with the results. Conclusion The main purpose of choosing cones and walnut shells grown in our country is to contribute to the amount of oxygen in the atmosphere and green areas by increasing the cultivation of pine and walnut trees. In the tests of the samples, it was determined that the highest STL was 63.27 dB in the concave and egg-shaped sample, and 62.41 dB in the concave walnut shell and egg form. It is envisaged that the materials we obtained can be used in the sound insulation of machines and devices that produce 85 dB and above sound harmful to human health according to ILO and WHO standards.
