CAT-SQ for CAT-System is a system that calculates psychological acoustic evaluation metrics.
CAT-SQ for CAT-System is a system that reads measurement data files recorded by Catech's CAT-System and other measurement systems, and calculates psychoacoustic evaluation metrics. Currently, only the magnitude of noise levels is used as an evaluation criterion, but rather than indiscriminately reducing noise levels, it has become necessary to create sounds that feel pleasant, sounds that evoke a sense of tranquility, and sounds that embody those qualities.

Company information
Our company develops vibration and noise measurement systems, sound source detection systems, thermal measurement systems, link systems with mode analysis and finite element methods, measurement instrument control systems via GPIB and RS232C, and model-related systems (HILS). We provide general-purpose systems such as the "CAT-System," which uses commercially available A/D boards to measure and analyze experimental data on vibration, noise, strain, temperature, etc., on a computer, as well as "physical model construction tools." Additionally, we also accept the construction of customized systems for various vibration analysis, noise analysis, and thermal analysis based on non-standard system configurations and specific output files for different companies. Furthermore, we engage in the sale of equipment related to these systems and provide technical consulting services.
