Patent number: 8855329Abstract: An active noise control (ANC) system may be implemented to both sides of a fan, such that both directions of the noise emitting are treated to reduce the overall noise. The impact on airflow is minimal, and the technique is very effective in a broad range of low frequencies. Passive sound-absorbing materials may be included for attenuation of high frequencies. The resulting quiet fan produces a low level of noise compared to any other device based on fan, which produces the same capacity of airflow. The quiet fan may be incorporated in any mechanical system which requires airflow induction such as: computers, air conditioners, machines, and more.Type: GrantFiled: January 20, 2008Date of Patent: October 7, 2014Assignee: Silentium Ltd.Inventors: Alon Slapak, Tzvika Fridman, Ofira Rubin
