The S-Fan Demo is a generic silenced axial-fan equipped with hybrid (both active and passive) noise control means.
This demo can be used to calibrate the S-Cube Development Kit (SCDK™) or to practice on systems where the mechanical medium and ANC components are already well defined. The Demo provides a good comparison between the passive noise reduction and hybrid noise reduction on a single system.

The SCDK™ provides a do-it-yourself ANR development tool that can be used for the application of loud electronic equipment. Developers and engineers can leverage it to implement noise and vibration reduction. The controller unit integrates all the required function: Sound generator, equalization, amplification and the active adjustment processor. The controller is connected directly to the loudspeakers. The controller allows the designer to reduce up to 10dB reduction in addition to what the acoustic materials will diminish.
Broadband noise reduction up to 10dB(A) beyond the reduction achieved by acoustic material.Adaptable for both point-to-point and point-to zone ANC applicationsIdeal for acoustic and vibration applicationsReal-Time Adaptive AlgorithmsSelf calibrating systemStandalone modeUser-friendly, PC- Based USB interface for the calibration processS-Cube™Speaker2 MicrophonesUSB cableDC 12V adapterInstallation CD
Reduction of generator noise during foundation work of new construction site
Soundproof Cover : Blocks the noise by covering the generator from all sides(It also has excellent visual effects).Inlet Duct: Controls the generator internal temperature from 40℃ to 50℃ANC Cooling system : Installs a high performance blower inside the soundproof cover to cool down the generator, and reduces noise from the blower using ANC technology(Maximum 15dB reduction).| Measurement location | Original noise | Noise after installing apparatus | |
|---|---|---|---|
| 10m x 1.5m (H) | 67.9 dB (A) | 61.7 dB (A) | ▼ 6.2 dB (A) |
It is IT Solution of the function that it was optimized with perfect noise shielding and effective cooling efficiency.

The Active Silencer Fan Tray™ (ASFT™) is a fan drawer, designed for assisting ventilation by forcing air into and out of an enclosure, while preventing noise from escaping.
The unit is lined with acoustic material and equipped with Silentium’s proprietary noise-cancelling technology which is highly effective in reducing low-frequency noise. When combined with unique high quality acoustic materials this product achieves unprecedented spatial noise reduction over the entire frequency bandwidth of the audible spectrum.

Hearing Protection Ear-set Using IoT-based ANC Technology
The ANC and voice filtering technology are added to the ear-set
to reduce noise and enable smooth communication.
Create new sound to control the ambiance in the vehicle.Noise level reduction using ANC technologyProvide a comfort riding for passengers with sound designed for optimum comfort.(High-quality sound)
Reduction of HVAC noise in vehicleIt is possible to apply front HVAC, rear HVAC, etc.
Reduces noises inside and outside the vehicle using the speakers on the door or the headrestANC can reduce various noises such as road noises, engine noises, wind noises.
