Technologie d'annulation des décibels

Annulation des décibels™
Technologie

Decibel Cancellation™ is HisoAir’s system-level approach to balancing clean-air delivery and operating noise. It combines optimized airflow paths, suitable filter resistance, blower selection, structural vibration control, and acoustic materials to help deliver high airflow with lower operating noise.
The technology focuses on airflow and acoustic optimization rather than electronic active noise cancellation.

Performance de purification de l'air silencieuse

Instead of relying on a single component, HisoAir evaluates the filter, blower, air duct, housing structure, motor mounting, and operating controls as an integrated airflow system. This helps reduce unnecessary pressure loss, turbulence, vibration, and operating noise while maintaining the required clean-air delivery rate.

Airflow and Acoustic Performance Validation

HisoAir evaluates airflow, pressure, CADR, noise, power consumption, and system resistance during product development. Testing results are reviewed under defined product configurations and operating conditions to support airflow-path optimization, blower selection, filter matching, and structural improvement.

Optimized Air Duct Design
Dual-side air intake and a carefully designed outlet path increase the available intake area and help reduce airflow resistance. This supports the required airflow while allowing the blower to operate at a more moderate speed.

Matériau de réduction du bruit

Acoustic and Vibration-Control Materials
Selected acoustic materials and vibration-isolation structures are applied around the motor and housing to help reduce transmitted vibration and airflow-generated noise.

Forward-Curved Centrifugal Blower Design
A compact centrifugal blower is selected and matched to the air duct and filter resistance. Operating the blower within an appropriate efficiency range helps balance airflow, noise, power consumption, and product size.

Nous utilisons un ventilateur centrifuge de type "Forward-lean", qui est plus petit et moins bruyant. Le moteur ne tourne pas à plein régime, afin de maintenir une vitesse modérée et un faible niveau de bruit.
