Noise-Level Test Prima Klima Inline Fan 2-Speed 220/360 cbm with Silencers

Inline Fan Noise-Level Test
Prima Klima 2-Speed Fan 220 / 360 cbm with and w/o silencer.
Silencers used are 60cm with a 5cm damping layer.
In this noise-level test we will demonstrate the difference in sound pressure level of the fan by running it with and without silencers.
The first shown value is the soundlevel in status OFF just to show you that the sound of a very quiet room is somewhere around 30 decibel.
Please have a look: en.wikipedia.org/wiki/Sound_p...
The camera with the microphone is 2m away from the fan so the recorded sound will give you a good impression too.
So if you dont trust the measuring device, just trust your ears.

Rohrlüfter-Geräuschkulisse-Test
Prima Klima 2-Speed Lüfter 220 / 360 cbm mit und ohne Schalldämpfer.
Die verwendeten Schalldämpfer sind 60cm und haben eine 5cm Dämmschicht.
Bei diesem Lüftertest demonstrieren wir anhand eines Lautstärke-Meßgeräts den Unterschied im Schalldruckpegel bei Betrieb des Lüfters mit und ohne Schalldämpfern.
Der erste eingeblendete Wert ist im ausgeschalteten Zustand gemessen um zu veranschaulichen das sich der Geräuschpegel im vollkommen ruhigen Raum bereits bei 30 Dezibel einpendelt.
Siehe auch hierzu: de.wikipedia.org/wiki/Schalld...
Die Kamera mit dem Mikrofon steht 2m entfernt von dem Lüfter sodass auch der aufgenommene Sound einen guten Eindruck über die Unterschiede vermittelt.
Also wenn du den Werten auf dem Messgerät nicht traust, vertrau einfach deinen Ohren.

Here's how to make this system ultra silent.
Place the fan on a carbon filter on one end. Place a insulated ducting on the other, use those big rubber clamps. Not the steel duct clamps, they vibrate to much. Also use straps to hang them. Now Place that system in the tent for more sound reduction. And use a smart controller. (Min/max speed automatically to a set point. Smscom has a cheap wall plug controller with external temp control cable. You only need minimum speed for led lighting. Just a negative pressure will eliminate any smells. Place that in a simple box with eggfoam inside. Thats what i use in my bedroom. Its so silent i sleep next to it. If you are worried about Minimal sound reaching out of the room you can even put eggfoam on the cracks overlapping the door of you room. Or you could just use a mdf silent box with insulated ducting. But they are more pricey. Hope this helps.

The size of the silencer btw..

Thats to loud

[@olivieolivier1894]

the silencers are not effective, because I used x2, two silencers, one at each mouth entrance and low from 77db to 69 db my rvk200 of 1080m3, some Spanish brand sonoconnect soundproof ducts lowered me to 70.5 db, using 70cm on each side, Well, the silenced duct has a value of 3.80 euros per meter, cheap but the silencer, the silencer duct in my case of 60cm and 200mm is worth 200mm is worth a minimum of 50 euros, for 60cm of silencer, which has 4cm of low absorbent material class, 25kg wool or other low density per kg per m2 and density at a thickness of 40 millimeters 4 cm of wool, the silencers are the biggest expense less performance, now disappointed with the result of the silencers that I buy confident in 20 to 28 Result db I will desistalare them and buy spending more than one for bad information and deception because they are useless, the change is noticeable 4%, a modern conduit of the latest design, it is French it is called phonic trap, I am sure that replacing my s traditional rock wool and aluminum sonoconnect ducts for this phonic fabric with cotton that is just as effective as wool plus the polyethylene layer will have better results than with silencers and the obsolete technology of traditional aluminum soundproof tubes plus rock wool plus aluminum Micro perforated, as I will trust the phonic trap brand, I found a virgin brand phonic trap from France that looks good, in my country Spain Madrid, we only have silencers that do not give good results and obsolete aluminum pipes plus rock wool Simple, thank God I found modern French ducts which I have not used or tested but I trust, my idea is to use my size of 20cm to which I am going to micro-perforate and the outer layer to add rock wool of construction of 40kg and 5cm more thick to add to the tube that thanks to the metal structures does not obstruct, then the 20cm tube has a total of 24 I stick 5cm good rock wool and have go 29cm I will add 1cm of acoustic membrane for low frequencies of 2mm and then a total of 30cm I will put another 31 cm conduit inside unmodified phonic trap, in plan an outer layer that protects, total a tube for a 200 extractor with a conduit of 315, but 115mm of absorbent layers

Dude, plz add some punctuation to your text. Its impossible to read

Mal im Ernst.......wollt ihr uns komplett verarschen? Wenn ich in einen Raum mit 30 db grundlast einen Lüfter mit 39 db anschalte, was zeigt das db Messgerät an?
Richtig....39 db. 🤦‍♂️
