How to choose a probe for on-site measurement of sound power, do you know?

How to choose a probe for on-site measurement of sound power, do you know?

Today, after seeing the article "Measuring Sound Power Using a Cubic Microphone Array in Small Rigid Spheres" published by Professor Niels Consten and his team, I felt it was incredibly practical, so I quickly came to share it with everyone. I won't go into detail about the various theoretical principles in the article; if you're interested, you can check the original text on the website (https://pub.dega-akustik.de/DAGA_2019/data/articles/000203.pdf). After reading the article closely, I created a table comparing traditional probes with spherical probes based on the research in the article, which you can refer to:

The measurement results are shown in Figure 6. Overall, all sound absorption curves for each material thickness match well with the material specifications provided by the manufacturer. Even for the impedance tube measurements, there are differences between all the curves, but they are minor. The general trend of each curve is comparable. For example, the "drop" around 3 kHz in Figure 6a appears in all three curves. This indicates that the SONOCAT method using LPW for on-site measurement of material surface sound absorption is reliable.

Acoustic testing is a series of technical activities used to evaluate and measure sound and vibration characteristics. It includes measurements of sound intensity, frequency, propagation, isolation, and absorption. In people's perception, acoustic testing is applied in noise control and environmental monitoring, product design and manufacturing, architectural design and spatial optimization, materials research, and the development of cultural heritage protection. However, this is only part of it; in fact, acoustic measurement has wide applications in various fields such as medicine, virtual reality, and wireless communication. The role and potential of acoustic measurement are continuously being developed and utilized. In the future, acoustic measurement will play more roles as an important driving force for technological innovation and social development.

Field measurements mainly include precise measurement of sound pressure levels, analysis of sound intensity and sound power, detailed analysis of frequency and time characteristics, visualization of sound field imaging using acoustic cameras, three-dimensional sound intensity measurement technology, acoustic holography technology, measurement of material sound absorption and sound insulation performance, long-term monitoring of environmental noise, as well as acoustic navigation and positioning technologies. These technologies can comprehensively cover multiple dimensions such as sound intensity, frequency, time, and spatial distribution, providing strong technical support for the assessment and management of sound environments.

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.
