Development and validation of a portable test stand for sound measurement near the building fasade

The article presents capabilities and application ranges of a newly designed portable device (a test stand) for a measurement of sound waves reflected from a building's facade. What is more, the developed device can be also used to monitor the environmental noise. A detailed description of construction and assembly of the test stand was included. In many countries, ISO 1996-2 standard is a guideline on how to measure and assess acoustic environment. In this study, we made reference to the -3 and -5.7 dB corrections recommended in ISO 1996-2, depending on the location of the microphone at the facade of the building. Significant discrepancies between standard norm corrections and experimental results were indicated. In measurement conditions on the facade of a tall building, the research usefulness and ease of use of the constructed portable test stand was demonstrated. Thanks to the simplicity of the construction and the applied meter, the measurement stand allows to perform advanced research on any high building facades.
