Our company not only develops and sells measurement systems necessary for evaluating the acoustic properties of materials, but we also offer contract testing services using those measurement systems. Our experts in acoustic material property evaluation will thoroughly listen to the purpose of the tests and other requirements, propose testing services that meet your needs, and provide optimal outputs.

• Contract measurement

STRATI-ARTZ is software designed to predict the acoustic performance (sound absorption rate and transmission loss) of layered soundproofing materials. By utilizing a rich database of material parameters, it simulates the acoustic performance of sound-absorbing and sound-insulating materials under various conditions, which not only reduces prototyping and measurement costs, leading to time savings, but also enhances development capabilities through multifaceted considerations.

• Acoustic Analysis

The absorption rate and transmission loss in the main frequency range (100Hz to 5000Hz) can be measured at once using a single acoustic tube. Since there is no need for multiple measurements with different sizes of acoustic tubes and samples, data inconsistencies do not occur, and the labor required for sample preparation (cutting) and measurement can be significantly reduced.

• Testing Equipment and Devices

The WinZac 8 wideband vertical incidence sound absorption rate measurement system is a new acoustic measurement system that can stably measure wideband sound absorption rates and transmission losses with a single sample. By using 8 microphones (16 microphones during transmission loss measurements), it is capable of measuring with high precision and up to more than twice the frequency compared to conventional acoustic tubes of the same diameter.

• Other measurement, recording and measuring instruments
• Testing Equipment and Devices

The microphone moving device was developed by our company as a world first and has now become an essential tool for acoustic measurement. Understanding the acoustic radiation characteristics from sound sources is very important for conducting acoustic power level assessments and implementing sound source countermeasures for the objects being measured. By automating the complex positioning of microphone measurement points, we ensure reproducibility in on-site acoustic measurements and achieve labor savings. It is also easy to control from a computer, allowing for the construction of a flexible automatic measurement system.

• Other measurement, recording and measuring instruments

Automated movement and positioning devices are effective tools for supporting automation and labor-saving, but it can be challenging to find off-the-shelf devices that fit each specific purpose. We provide systems tailored to your needs based on the custom technology developed through our extensive experience in acoustic measurement, which encompasses a wide range of subjects and methods.

• Other measurement, recording and measuring instruments

In acoustic psychological evaluation experiments, we assess the subjective aspects of the impressions people receive when they hear a certain sound. The results obtained from the evaluation experiments can be quantitatively understood by using statistical processing to grasp the trends. Our company provides comprehensive support, from proposing experimental methods tailored to your objectives, to processing and creating sound sources, conducting experiments, and analyzing results.

• Contract measurement

AirResys is a system that measures the flow resistance, which is the most important parameter among the Biot parameters that characterize the acoustic properties of porous elastic materials.

• Other measurement, recording and measuring instruments
• Testing Equipment and Devices

Torvith is a system that measures the material parameters of the Biot model, which characterizes the acoustic properties of porous elastic materials, including tortuosity, viscous characteristic length, and thermal characteristic length.

• Other measurement, recording and measuring instruments
• Testing Equipment and Devices

The elasticity measurement system is a system that measures the parameters related to elasticity, namely "Young's modulus" and "shear modulus," which are material parameters of the Biot model that characterize the acoustic properties of porous elastic materials.

• Other measurement, recording and measuring instruments
• Testing Equipment and Devices

We will propose feasible methods using our facilities for evaluating the acoustic performance of parts, including interior and exterior components in various consumer products and vehicles, after hearing your objectives.
