The invention discloses a multi-
frequency noise filtering range hood with through holes distributed according to an arrangement region. The range hood is provided with a range hood main body and a
noise filtering device capable of reducing multi-
frequency noise, wherein the
noise filtering device is assembled on the range hood main body; the
noise filtering device is arranged as a panel on which the through holes are distributed and the through holes are used for counteracting the multi-
frequency noise, and the through holes are distributed on the noise filtering device according to the arrangement region; the noise filtering device can keep a good
noise reduction effect for a long time, the noise filtering device is easy to maintain, and dust,
grease and the like on the surface can be cleared in a detached mode; the noise filtering device has the advantages of being low in cost and high in reliability; the noise filtering device is made of a material which has the advantages of
corrosion resistant, chemical resistant, and not prone to be damaged, so that
narrowband noise and
broadband noise can be effectively reduced, the frequency range is wide, and the multi-frequency noise canbe reduced.
