HouseTech launches WhisperSilence ultra-quiet range hood series operating at 35dB, equivalent to library-level quiet conversation. Traditional range hoods typically run at 50-60dB, representing 15-25dB reduction and approximately 70% perceived noise decrease for users.
Magnetic levitation motor technology eliminates mechanical friction noise with fully suspended rotor operation. Motor lifespan exceeds 60,000 hours, 2x longer than traditional bearing motors. Near-zero vibration transfer suppresses noise generation at the source.
Noise Reduction Technology System
AeroAcoustic duct design achieves 40% turbulence noise reduction through CFD-optimized airflow pathways. Impeller blade angles refined through 1200+ simulation iterations reduce flow separation and vortex generation. Duct system noise reduced by 8dB+ at equivalent airflow rates.
Active noise cancellation system includes 4 high-sensitivity microphones and 2 low-frequency speakers generating real-time inverse sound waves. 10-15dB noise reduction depth targets 200-1000Hz motor electromagnetic noise band. System response time ≤10ms adapts to speed changes in real time.
Complete unit employs 5-layer composite damping structure with 45 Shore A rubber pads isolating motor-housing vibration transfer. 25mm thick internal acoustic foam achieves ≥0.85 absorption coefficient. Bottom air outlet features silencing chamber reducing exit noise by 3-5dB.
Product Series & Market
WhisperSilence series includes 6 models covering wall-mounted, island, and under-cabinet installation types. Airflow range from 600m³/h to 1200m³/h accommodates various kitchen space requirements. All models maintain 35dB quiet level without noise increase at higher performance settings.
