The air ducts are nearly completed. The system will work like this;
- Refrigeration unit will cool the entire lobby area
- Fans will blow the cooled air down the silver ‘sandworm’ pipes
- Cool air will come out at the front of each room (through the ceiling baffles)
- Warm air will escape into the lobby via ventilation holes at the back of each work room…
- …and be cooled by the refrigeration unit
- There will be a fan switch and speed control in each workspace, so the occupant can just switch it on whenever cooling is needed
The air path is broken up into zigzags to prevent bass frequencies from travelling; the ducts are lined with rockwool & fabric. My 8-year-old has pointed out that in the event of anyone, er, ‘trumping’, this air will be circulated round and round the building at slightly different temperatures. So we will need to open the lobby door occasionally.
The cunning part is concealing all the ducts necessary to achieve all this. As mentioned before, the cool air enters via the ceiling baffles, having made its way through the soft pipes that run alongside the ceiling. In the lobby area there are two more ducts. This is the one for the live room, in its pre-covered state – you can just see the silver pipe emerging from the back and carrying the cooled air off to the right.
The second foyer duct – the one supplying the control room – is practically invisible now because it’s built into the door frame, so here are a few photos of it under construction.
The basic construction of the control room bass traps is now complete. The principle of a bass trap is that it stops particular bass frequencies from being accentuated by the construction of the room – here’s an article about the physics of listening spaces. This is to ensure that the monitor speakers are giving an accurate sonic ‘picture’ of the instruments/sounds in the mix.
Because low frequencies have a longer wavelength, they can only be broken up by large objects. Howard’s design of bass trap, from what I can tell, combines a ‘membrane’ and ‘broadband’ method of construction – plywood panels, with air gap, rockwool and fabric covering. All this means that we need some very large bass traps in the control room. So I may end up with a slightly smaller sofa than I originally thought!
On other news, Artis has been getting me and Jeff into Latvian folk-metal. Here’s Skyforger – chanting a 500-year-old folk song on the beach, then straight into some driving speed-metal riffery. Check out the bagpipe solo!
