Fan Noise Level at Maya Hurley blog

Fan Noise Level. The sound generated by a fan depends on the motor power, the volume capacity, the static pressure increase and the discharged volume. The sound level is 36 db (a) at the highest of the 3 levels. In general terms sound power level (l w) cannot be directly measured. In all 3 rotational speeds, the sound level remains very quiet. This is the lowest possible sone rating. However, there is a problem measuring the sound power level (l w) of a fan. The term fan noise describes a type of unwanted sound produced by the fan or its components which may require corrective action to bring the fan. The purpose of this presentation is to educate industry professionals about the basics of fan noise and the ratings published by various fan. Naturally it increases a bit in the higher the speed settings. Typical bath fans range anywhere from <0.3 sones to 6.0 sones. On this chart, we have created a visual scale to give you a real world representation of these perceived volume levels as a guideline for you when looking at the db level for a fan. Below is a chart detailing what sound level you can expect out of a certain sone level: In order to determine fan noise, sound power level (l w) is what the acoustic engineer needs—something that is constant all the time no matter what the fan’s operating environment might be. The empiric expressions below can be used to indicate.
