Sunon Super Silence Fan Series – unheard sound quality
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.
SounTo 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).
