Sound Attenuation with Lunos HRV System
I’m planning on installing a pair of Lunos e2 HRV units in the small house I’m building. The idea was for one of the two to go in the bedroom and one in the living room, to help distribute fresh air throughout the house during the push and pull cycles.
It was brought to my attention that the Lunos unit — beyond all the fancy bits — is fundamentally an always open 6″ hole in the wall. Exterior noises将要come through. What I want to know is, practically speaking, how much noise gets through?
The Lunos units do have integrated sound attenuation built in to the tube, on the order of 42dB. There is also an optional outer hood with additional sound attenuation to the tune of 6dB. So it’s not nothing and it is better than just a plain 6″ hole in the wall.
然而，对于那些与Lunos单位的人来说，这有多重要？如果这个小房子邻近邻居用鸡，山羊和狗等，那么在卧室里安装一个单位可行的或它会允许太多的噪音？

我会说通过的噪音量类似于通过劣质乙烯基窗口的声音。如果有人在它之外（或案件中的动物），你可能无法听到他们所说的话，但你可以告诉有人说话。所说，有一个声滤器，您可以达到Muffle外部噪音。我只有标准单位，所以我不能和那个话说。
Thanks, Levi. Is that "acoustic filter" the optional outer hood I referenced or is there even a third sound attenuation option that I didn't yet see?
Kurt,
I've never been around a Lunos. How loud is the fan?
Honestly, I haven't been around a Lunos unit in person, either! My impression of the sound is entirely based on videos I've watched plus the published specs. Given all that, I'm assuming that the fan will be inaudible on low at 6' to 8' and essentially quiet white noise in medium and high. Ceiling fans run nearly 24x7 in Phoenix and those will always be making more white noise than the Lunos is rated to make.
最糟糕的情况，如果它确实提出了晚上不可接受的噪音质量，我的思考是它可以简单地关闭。但这正是为什么我询问外部噪音 - 如果来自外面的噪音通过相对畅通无阻
Yes I think we are discussing the same acoustic filter. I would contact 475 building supply about it. They’re reps have been pretty knowledgeable from what I’ve seen. As for noise from the unit itself, on low I have to get right up next to it to hear it. I live in a city, so the exterior noise coming through the lunos is definitely louder than the unit itself. Even on high, which we’ve only done during covid situations to increase ventilation, it’s not terribly loud.
We got a couple Lunos in our ADU within 100 feet of pigs, goats, a chicken coop and all the other McDonalds critters.
Yes, the Lunos leak some of the critter noice, especially the big pigs but my main concern is the noice level in a bedroom. If I could change my setup I would put the bedroom unit in a closet to minimize the noice. For comparison the Lunos sound are more distinct and noticable than the Mitsubishi mini split we have in the building.
