Addressing the crack along the rear wall / floor corner more or less as per Stuart's instructions. The cut down top board sections used to reach the wall were happily not glued to the sub floor and so easily removed. The rest of the top boards were glued. They are decent tongue and groove system, so...

Indeed. I can't believe the speed you are constructing it too, so fast. I assume it's been in the planning for a couple of years?

Yes, the Knauf RS45 is 45kg/m3, specs below, I think it is very similar to the Rockwool RS45; https://www.knaufinsulation.co.uk/products/rock-mineral-wool/earthwool-building-slab-rs45 I think Glenn Stanton used something similar, but may be mistaken. In the Rod Gervais book p.269 it mentions using 3...

The 18mm plywood and MDF cuts arrived yesterday afternoon, just in time to prepare a quick test for a rehearsal session in the evening. No screwing or green gluing of the board, just the 3 layers lying loosely on top of each other, on top of 50mm thick Knauf Earthwool RS45 insulation slabs. The came...

Right now, it's looking like roughly 570cm long by 350cm wide, but that was before the tanking coating went on, and not allowing for any variation from wall roughness. But somewhere close to that. (OK, so that's just a few mm we are talking about, but I do like to be accurate! :) ). Nice, that is a...

Your build really is stunning. What will the inner dimensions of the studio be when finished?

Nice one, that makes sense, thank you

Excellent, I will make it so :-) Looking closely at the photos I took before putting the skirting board back on (there was a recording session today), it looks likely that the wood floor and sub floor don't align perfectly at that edge anyway, which would certainly be useful. Here's something else I...

Cheers Stuart, yes the sound leaking into adjoining rooms seems "tighter" and more directional or somesuch as well, it's fascinating. Probably because leakage to the landing and subsequent stairwell and halls has been substantially cut. I like it a lot; as someone who values silence as wel...

As a first step I've been making the improvements in sound isolation discussed above. I measured the attenuation to adjoining rooms with the UMIK-1 for both SPL figures and an REW sweep to allow proper checks on these improvements. Done so far; - filled in the holes in the plasterboard walls. There ...

What Dan says!

Also remember that certain positions can improve the SPL plot (frequency domain) while making the waterfall and spectrogram (time domain) worse, and vice versa. So keep an eye on both when evaluating the different positions.

I'm a bit rushed at the moment, no time to prepare screen captures, so will have to comment with text only at the moment sorry. I'll try to be clear in my words :-) I noticed a big improvement in the high end which are much "smoother" above 2Khz, Good, that's exactly what one can expect fr...

I only have time for a short comment just now sorry! Some of the bad stuff you notice might be from reflections from your desk and/or rack. There is a peak in the impulse plot for both left and right speakers about 1 millisecond delayed from the direct sound. This should be under -20 dBFS and it is ...

Bummer!

You might be able to repaint behind the wall with a telescoping paint roller or wash brush.

Good point, thank you. It would also allow more variations e.g. an 1800x1800mm riser, large enough for many drum kits. Cam locks and dowels as found on many Ikea type flat pack furniture could be a good way of holding the risers together temporarily. There's a double end version that allows the dowe...
