Fans, large or small, produce noise. Fan noise varies, depending on fan size, horsepower, airflow, type of fan, wheel static pressure, rotational speed, and others factors. Generally, silencers are used at the intake or discharge of fan installations for treating noise. Silencers use an absorptive-type design; the effectiveness of absorption material progressively reduces noise.
