Just for those unfamiliar with the hum generated by multiple fans, the cost of a grow box silencer may seem overpriced. In fact, modern devices for capturing and attenuating the sound vibrations of the air are extremely meticulously thought out creations. Only with knowledge of physics at the level of the XXI century, it is possible to compactly place sound-absorbing materials, achieving maximum efficiency.
REFERENCE: not all vibrations of air with the parameters of sound waves turn into sound. See paradox .
In principle, the price of composite materials from which silencers are assembled is only half the cost of the device. No less serious effect is exerted by fibers correctly oriented in the structure of the material. It is they who absorb most of the waves, the low-frequency spectrum.
A characteristic feature of noise in growboxes is a low-frequency rumble. It has extremely good structural permeability. It seems to pass through the material itself, and when it reaches any open surface, it uses it as an impromptu resonator.
IMPORTANT: in a quality silencer, all threaded connections are equipped with two sound-absorbing gaskets.
But this spread of sound is also easy to deal with with polyurethane foam or rubber pads. They fit in all places where there is contact between the working mechanism and any surface. When viewed schematically, the fans in the grow box will appear to be suspended, in which case, it is only acoustic, not structural noise that needs to be suppressed.
Duct silencers will almost completely eliminate sound, and the acoustic masking of the grow box will settle at a safe level.
