A new breeze for researchers who want to accelerate noise reduction research!
The ANC noise reduction testing system is a system that cancels and reduces noise by using sound that is out of phase with the noise. Since developing a prototype noise cancellation device in 1993, we delivered an ANC evaluation device to a certain university in 2005. From 2010 to 2019, it has been implemented targeting various noises such as projectors, home appliances, and ventilation fans, achieving significant results. The ANC noise reduction testing system can eliminate "low-frequency noise below 2kHz" that cannot be silenced with sound-absorbing materials. For periodic noise, it can reduce noise levels to below -20dB (1/10) to -40dB (1/100). <Features of the ANC Noise Reduction Testing System> - It supports both feedforward and feedback testing. - It has a built-in oscilloscope and frequency analyzer, allowing for various data analyses related to noise and enabling the determination of filter coefficients for reduction. - It can save and read data during testing, allowing for long-term ANC tests that can last several days. - The ANC noise reduction testing system is suitable for customers conducting research and experiments on noise reduction. *For more details, please download the PDF or contact us.
