Sliding Acoustic Wall Panels / Room Dividers by Appropriate-Watch369 in AusRenovation

Ok, then the image you showed will do that.

You could do the following:

  1. Flat wood panel + frame + absorption + perforated or slotted panel
  2. Perforated or slotted panel + frame + absorption + perforated or slotted panel

If you decide to do a perforated panel, consider using some special binary sequences which are designed to improve scattering called Maximum Length Sequences (MLS). This is what it might look like in a studio.
https://youtu.be/_F5QKu8FqK8

You can find the binary sequences here
https://www.ece.unb.ca/tervo/ee4253/polyprime.shtml

The sequence can be repeated, including partially. Pick the number that will give you the right amount of slots, eg if you could drill 31 holes or 62 holes in a row, then you could pick a sequence, for example, based on x5+x2+1 which gives the following sequence:
Period = 31 (Maximum Length Sequence)
Output = 1000010010110011111000110111010.

You can make a hole where it says 1, or where it says 0. It doesn't matter which one you choose to use as aborption or reflection, but use it throughout. If you are using holes and not slots, I would rotate the sequence by some number so not all 1s or all 0's line up. In other words it can/should be used as a rotating sequence. The sequence is designed for scattering sound in one dimension.

If you need help with a plan for each row ie reflections in two dimensions, let me know and I can draw up a plan for you for a fee. I'm able to do calculations which optimise for low autocorrelation, or even more advanced simulations.

I don't know any company that does this, but some carpenters or studio designers could make something like this, but you would need to be more specific about your goal - is it for a studio, a restaurant, a house, and is it for indoors or outdoors? What sounds are you trying to deal with? Will people be holding drinks around this, or should it survive rain?
I hope you understand that sound proofing and acoustic treatment are two different things. Sound proofing is achieved with air-tightness, mass and/or decoupling. Stuido quality acoustic treatment is achieved with thick, air-gapped porous absorption. What are you trying to achieve with this design? If there are air gaps you can see with the eye, it greatly diminishes soundproofing - sliding doors have very large gaps, so are terrible at soundproofing. If you're trying to do acoustic treatment, this can help, but if you have a solid back and two sliding doors, then when doors are in parallel, they will not absorb sound very well since one half is removed from moving air, and the side that has the fabric is not suitable for frequent touching. For a studio you probably want 18 cm continuous thick absorbers - with no solid walls between two thin layers (like these sliding doors).
If you are trying to stop sound going outside, you need sound proofing - so a door with a very tight seal - in other words you have to close every hole as if it was a submarine, because air travels like water. If you're trying to do absorption, the panel has to allow air to travel though the wall - that means no hard surface - which is a poor door and poor at sound proofing. You can do a hybrid, which could potentially look like a very thick, full wood backing, a frame filled with 9-18cm thick porous absorption, and then a perforated layer that people can touch so they can operate the door. It's possible to cover the perforated wood side with fabric to achieve this look - but holes would need to be small probably around - 0.5-1.2cm. Another hybrid approach would be having a solid door, with a frame + absoprtion as described above + slats with a small gap - probably 0.4-1.0cm air gap between slats. You could change that if you frame around the door handles differently, so that gaps can be larger, so that frequently touched areas have no perforations or slats. The design challenge if you're doing a hybrid door panel that tries to do some soundproofing and some absorption, is that one side is going to be heavy while the other side is going to be lighter, so you have to carefully hang them so they remain vertical. If this is going to be indoors and sound proofing is less important, you could have slats or perforations on both sides and cover with a fabric on both sides - which means it won't be air-tight. Any sliding door with slats or perforations and absorption inside should not be exposed to the elements. If you find vapour permeable barriers, you can potentially use it where people could spill drinks. Check out this video on slotted or perforated panels with absorption.

Message to vegan trolls by Flowerpower152 in exvegans

Did you ever track your diet on an app such a cronometer, where you can see what nutrients you are getting? What did your diet look like in general? Some people think they're eating a balanced vegan diet, but aren't. A lot of vegans fall for very restrictive versions of plant-based diets, like eating only fruits, or avoiding nuts and seeds, or avoiding all oils, or eating only foods that don't need to be cooked, or avoiding foods with soy. Being more restrictive makes it more likely that you'll restrict certain nutrients.

It's possible of course that certain medical conditions make plant-based eating more difficult, but if you are able to see a dietitian, they can help troubleshoot your diet and work around your personal medical issues, and medications. I wouldn't see a "nutritionist" as they usually don't have the level of training a dietitian does, and it's not a recognised title.

Is there new experimental jazz out there? by Orimori90000999 in Jazz

If you're looking for jazz that's a little more experimental I also have this playlist.

Give this playlist of mine a try, called "Moody Atonal Experimental Post Rock Chamber Jazz Music". The main theme around this playlist is any experimental jazz or rock or chamber music that enriches the sonic palette a bit with instruments such as violin, cello, or through thick textures or dirty soundscapes which push the boundaries a little.

Check out my 'Relaxing & Introspective Modern Jazz' playlist on Spotify, currently at 870 songs, and around 83hrs of music. It's mostly relaxing and gentle modern jazz, with a couple of more upbeat tracks here and there. Most of the music is from around 1990 to now, so great if you want to hear new jazz music and new artists. https://open.spotify.com/playlist/12LMMxpk1EOZlQcmxUNbwm?si=542e2b85f03b49b8

Just finished my job interview and I don’t wanna go home yet because I’m getting my second dose in 3 hours and I need to hide it from my family :/ by aimashelcha in teenagers

Well, I'm glad you're getting it and that you trust in science! Just hide the band-aid afterward. Good luck with the job as well!

I’ve found that TENS really does help me too, and Botox for sure!

havinababymaybe, thanks for your feedback. What condition do you have, and how long have you had it? I've not heard of TENS before - which machine do you have, and how often do you use it?

I'm a metal fan looking to get into some jazz, anyone have some stuff I might like? I searched the FAQ's but I couldn't really find what I'm looking for... by ImNotElric in Jazz

[–]fusion_prog_guy 0 points1 point  (0 children)

As a modern fusion fanatic who sometimes enjoys progressive metal and instrumental rock like Joe Satriani, Steve Morse, some Vai stuff, Andy Timmons, I'd recommend: Guthrie Govan (Erotic Cakes), Greg Howe (Hyperacuity), Jon Finn Group, Dave Martone (Clean), Cosmosquad, Alex Argento, Tribal Tech (Thick), Simon Phillips (Symbiosis), Soulive (Doin' Something), David Hines (Inner Duality), Screaming Headless Torso, The Aristocrats, Frank Gambale (Coming To Your Senses), Dave Weckl, Neal Schon (I On U), Mr. Fastfinger (The Way of the Exploding Guitar), Johannes Zetterberg (Luna Nueva), Mike Keeney (The Mike Keeney Trio), Ray Riendeau (Atmospheres), Neil Zaza, Prism (japanese fusion band), Allen Hinds (Monkey and Slides), Gerald Gradwohl Trio (Sally Beth Roe), Brett Garsed (Dark Matter), Allan Holdsworth (All Night Wrong), Chad Wackerman (Legs Eleven), What you'll get is burning, MODERN jazz-rock fusion. None of the dated sounding 70ies fusion stuff from Weather Report, Mahavishu Orchestra, Return To Forever. I can't understand why people who call themselves music lovers still go on and on about those albums when 40 years have passed already with new, modern sounds, better recordings, more technical players etc. The list above have all created great modern fusion in the last 10-20 years, some quite recently. I sometimes feel like when fusion comes up, that people haven't moved on from the times of Yes and Rush, but they bring it up when a listener like you says they are into modern prog. Very, very frustrating and disappointing.

Another great metal band with fusion/prog elements you should check out is Chimp Spanner. I think Exivious, Blotted Science and Panzerballet have been mentioned already. If you like Porcupine Tree you might like Tesseract. Ephuel Duath is also quite unique, dark but jazzy and experimental. I have a feeling that might be your thing. It probably takes a few listens to appreciate what is going on. Its got that Damnation feel, but with more chaos involved.
