Acoustic sound measurement
Acoustic sound measurements are essential for analyzing parameters such as sound pressure, sound intensity, absorption, reflection, and impedance. These measurements play a crucial role in evaluating room acoustics, assessing materials, and optimizing sound insulation. Modern instruments like the Sonocat enable users to perform these measurements directly on site, or in situ, without the need for an artificial sound source or external setups.
Sonocat
The Sonocat is a portable all-in-one solution for advanced in situ acoustic measurements. The system allows you to measure sound absorption without an artificial sound source and provides real-time data on 3D sound intensity, particle velocity, sound pressure, sound power, and impedance.
The compact aluminum measurement sphere contains eight digital MEMS microphones and an internal signal processor, transmitting measurement data directly to a laptop via USB. Combined with the intuitive Sonocat software, this offers a complete solution for measurement, monitoring, and analysis.
Thanks to its plug-and-play design and capability for both handheld and stationary use, the Sonocat is suitable for quick spot measurements and scanning larger areas. Pre-calibration ensures accurate and reliable results for applications in building acoustics, research, and industry.
Our acoustic expertise
Measuring sound absorption on site
In situ absorption measurement enables the direct assessment of how much sound a surface absorbs, right on location, without the need for an artificial sound source. The Sonocat uses an innovative sensor configuration to capture reflections, absorption, and impedance in three dimensions. This provides a clear view of the acoustic performance of materials and structures in their actual usage environment.
Understanding sound dynamics and frequency
Sound pressure is a fundamental parameter in acoustic measurements, indicating the strength of sound waves. The Sonocat measures sound pressure across a wide frequency range from 20 Hz to 20,000 Hz, with a dynamic range of 29 to 116 dB(A). This makes the device suitable for a variety of acoustic applications, from quiet environments to high-noise scenarios. The data is digitally processed and can be analyzed directly using the included software.
Measuring direction and strength of sound
The Sonocat enables measurement of sound intensity in three dimensions. This means that both the strength and direction of sound can be captured with high precision. This data is useful for applications such as source localization, acoustic analysis in complex environments, and optimization of acoustic designs. With its unique sensor configuration, the Sonocat can perform point measurements or cover larger surfaces depending on the analysis needs.
