Sunon Super Silence Fan Series – unheard sound quality
Young Electronics announce new Sunon HA series Super silence fan. It is a significantly quieter version of current 40 to 120mm sizes. Noise is below the threshold discernible in daily living.
Product Features
• Very low noise – as low as 12.8dB(A) on the 40mm
• Wide operating voltage range
• 40mm to 120mm sizes
• Micro motor technology – maximizes air flow channel
• Customisation to meet specific requirements
Applications
• Audio
• Office equipment
• Medical
• LED lighting
Sunon’s long term objective has been the design and manufacture of a fan with optimal acoustic performance in an application or environment where silence is required
To do this they analysed response of the human ear to certain sounds using a Head Measurement System (HMS) from Germany’s Head Acoustics Company and 24-bit digital processing technology. Sound was analysed over frequency, time domain and psychological acoustics. Key parameters to measure were loudness, tonality, roughness, fluctuation, and sharpness.
To meet the above objective meant development of new micro-motor technology, new impellor design and air channel control.
The resultant Sunon Super Silent HA series fan noise is less than 20 phon. 20 phon is the minimal level of sound pressure loudness that is discernible in daily living.
In raw noise level terms this means a 40 x 20mm HA fan has a noise level of just 12.8 dB(A), the 120 x 25mm is 29.6 dB(A).
