Equipment/Program
Retained Equipment
- Multi-Channel Frequency Analysis Equipment
- The multi-channel analysis is equipment is the one that enables measurement and analysis of noise and vibration at multiple locations. At the same time, it is effective in the real-time monitoring, the real-time noise and vibration analysis, recording signals and post-treatment and precise analysis.
- Equipment Measuring and Analyzing Vibration
- We retain a sine sweeping shaker for an impact hammer and a sine wave excitation in order to experiment natural frequency, damping, dynamic stiffness and a type of mode etc. We have established measuring equipment applicable to diverse fields such as high-precision sensor measuring vibration, a general sensor measuring vibration etc.

- Noise Measurement and Experiment Equipment
- We retain multiple microphones, non-directional speakers that can be used with combination of a 4-channel analyzer and sound level meters that are convenient to carry and easy to be used for evaluation of environmental noise.
