In practical applications, the reverberation room method may be more suitable for architectural acoustics design; while for product development and quality control, the impedance tube method or the dual microphone method may be more precise. If environmental factors or timeliness issues are considered, one can try using professional acoustic measurement equipment like SonoCat, which can obtain the required data on-site.

A study conducted by Fons Peeters, Bert Peeters, and Ysbrand Wijnant has recently made significant progress in the field of acoustic characterization of noise barriers. This research was carried out in collaboration with M+P, located in Vught, Netherlands, and SoundInSight, aiming to quantify the relationship between laboratory measurements and field measurement results, as well as to explore the consistency of different measurement methods. The SonoCat multifunctional in-situ acoustic measurement device was extensively used in this experiment.

To investigate the sound propagation from Room 2 to Room 1, we conducted measurements using Sonocat at a location in Room 1 close to several sound radiating surfaces. During the measurement process, we gradually determined the sound intensity of these sound radiating surfaces. For this purpose, we used a continuous loud sound source in Room 2. Below are examples of the measurements.

To assess the noise leakage in the vehicle cabin, we conducted measurements using the Sonocat multifunctional in-situ acoustic measurement device inside a car driving on the NVH test track. Figure 1 shows the measurement setup (Sonocat device and software). Initially, we performed discrete point measurements to obtain preliminary acoustic data inside the cabin and familiarize ourselves with the acoustic environment. Subsequently, we conducted a comprehensive scan of the target interior areas suspected to cause noise leakage. The total time taken was approximately 30 minutes. By post-processing the collected data, we were able to identify the detailed information about the main noise emission surfaces within the cabin.

The event hall of Ernst-Christoffel-Haus in Mönchengladbach-Rheydt, Germany, recently completed an on-site measurement of acoustic characteristics aimed at assessing the sound absorption effects of different wall materials. This study, conducted in collaboration with Peutz Consult GmbH, provided an in-depth understanding of the indoor acoustic environment using advanced Sonocat technology.
