 +====Brief ==== 
 + 
 +The brief is a modular, low cost DIY friendly isolation booth for The Edge Recording Studio. Although mainly for vocal recording, the booth should be large enough for two people podcasting, or a small drum kit set-up, solo instrumental recording or as in isolation booth for guitar amp. 
 + 
 + 
 +=====Requirements===== 
 + 
 +  * fits minimum two people, including one wheelchair or mobility scooter 
 +  * meets or exceeds relevant ISO standards((https://​www.iso.org/​obp/​ui/#​iso:​std:​iso:​23351:​-1:​dis:​ed-1:​v1:​en ​ https://​www.iso.org/​obp/​ui/#​iso:​std:​iso:​4043:​ed-3:​v1:​en)) for acoustic isolation 
 +  * provides disability access  
 +  * uses commonly available, low cost materials 
 +  * fits with existing State Library decor and level of finish 
 +  * can be pre-assembled  
 +  * plans are open sourced at end of prototyping  
 + 
 +=====Design===== 
 + 
 +The prototype has been designed in Fusion 360((Fusion360 has a [[https://​www.autodesk.com.au/​campaigns/​fusion-360-for-hobbyists|hobbyist]],​ [[https://​www.autodesk.com/​products/​fusion-360/​students-teachers-educators|education]] and [[https://​www.autodesk.com.au/​campaigns/​fusion-360/​startups|start-up]] licenses available.)). The model is available on the web to view and annotate: https://​a360.co/​2Sfz8gC 
 + 
 +The design is a basic double walled shell, with variable configuration of panels and some parameters.  
 + 
 +The unit will fit within 1.8mx 1.8m, which is approximately half the width of the recording studio. 
 + 
 +Acoustics, internal fittings, fixings, penetrations and ventilation need to be considered at the meet-ups.  
 + 
 +=====Acoustics===== 
 + 
 +======Analysis===== 
 + 
 +Thanks to [[https://​jsouthaudio.com/​|Jon South]] ​ and Adrian Diery we have a plot of the room resonances:​ 
 + 
 +{{ :​facilities:​fablab:​fittings-custom:​vocalbooth:​vocalbooth_modes.jpg?&​800 |}} 
 + 
 + 
 +A similar tool can be found online [[https://​roomresponse.com/​|here ]] 
 +=====Acoustic Treatment===== 
 + 
 +Given the resonances present in the analysis, broad low frequency absorption is appropriate. Our challenge will be to fit effective absorption is such a small space. ​ Options include: 
 + 
 +  * Panel [[https://​en.wikipedia.org/​wiki/​Bass_trap|bass traps]] 
 +    * resonant 
 +    * broadband 
 +  * Corner bass traps 
 + 
 +====Low Frequency absorption with Acoustic Metamaterials==== 
 + 
 +Over the last few years, research into [[https://​en.wikipedia.org/​wiki/​Acoustic_metamaterial|acoustic metamaterials]] produced with 3D printers has achieved some interesting results for low frequency absorbtion. ​ While there have been no products released (that we can find) that use these materials, there are a couple of papers that explore some likely looking options.

 + 
 +https://​aip.scitation.org/​doi/​10.1063/​1.4895617 
 + 
 + 
 +=====Ventilation==== 
 + 
 +Once the booth has been framed up, we will look at the best way to build in ventilation. ​ Discussion at this point has been around a couple of boxes on the back of the booth, one for input, one for output, with a labyrinthine baffled ​ passage to reduce ​ noise transmission. 
 + 
 + 
 + 
 +=====Cabling==== 
 +Existing wall plate has a number of ports, wired into the studio patchbay : 
 + 
 +  * 4 XLR male sockets 
 +  * Stereo RCA 
 +  * HDMI 
 +  * 2 x ethernet  
 +  * 5 x BNC RGBHV 
 + 
 +The aim is to patch from these ports where possible. 
 +  
 +====Audio==== 
 +  
 +Six outputs from the booth (XLR) with 2 stereo inputs (TRS).  
 + 
 +====Video==== 
 + 
 +Single HDMI input. 
 +=====Disability Access==== 
 + 
 +Wheelchair access requires doorway clear access of 850mm. ​ The current door provides 880mm. 
 + 
 +====Access Ramp==== 
 + 
 +Maximum slope for wheelchair access is 10:1.  The base of booth is approx 116mm from the floor, which means the ramp must be approx 1200mm. ​  
 + 
 +====Door Access and Handle==== 
 + 
 +AS 1428.1—2009 13.5.2 Design and performance ​ - supplies the maximum force: 
 + 
 +(i) To initially open the door. …………………………………………………….. 20 N 
 + 
 +(ii) To swing or slide the door …………………………………………………….20 N. 
 + 
 +(iii) To hold the door open between 60° and 90°……………………………..20 N. 
 + 
 + 
 +=====Fittings===== 
 + 
 +====Furnishings==== 
 + 
 +Laptop table/​rest. ​ Foldable? 
 + 
 + 
 +===Mic Stand==== 
 + 
 +Permanent mic stand mounted on wall or ceiling with swing arm. 
 + 
 + 
 +=====Plans==== 
 + 
 +Plans will be generated as drawings from Fusion 360 - see examples in [[facilities:​fablab:​fittings-custom:​vocalbooth:​start#​resources|resources]].
