BUILDING AND ROOM ACOUSTICS MEASUREMENTS WITH SINE-SWEEP TECHNIQUE
I NIKOLIC, O-H BJOR · 2023
New measurement methods based on digital signal processing bring a number of advantages compared to well-established classical methods for the measurements in building and room acoustics, such as extended signal-to-noise ratio (SNR) and high distortion immunity.Importance of these techniques is confirmed by the fact that the International Organization for Standardization (ISO) is working on a standard for applications in building acoustics.The paper presents a real-time implementation of this measurement method, based on excitation with an exponential sinusoidal sweep and focuses on its practical use and benefits.Comparisons with methods based on maximumlength sequence techniques are also given. 2.
