Stargazer is also very nice. I've wanted to get this braiser: https://stargazercastiron.com/products/13-5-inch-braiser

It's not necessary. Clean the pan and dry it. Put on low-medium heat. Walk away for 10 minutes. Put in some oil. Small amount is fine. Give it at least 5 min to warm up. Cook something basic like vegetables or thin slices of meat. Give it a light clean with water after if you like, or not...

I don't know anything about metallurgy. I bought the Oigen Solitto pan because the naked surface is nothing like I've seen in other pans. Utterly homogeneous. I love the shape. Cooks wonderfully. It arrives in a very light gray, very fine. Oil from your fingers turns it black. With cooking and...

Your method has no effect beyond changing the ratio of direct vs. reflected sound intensity. By definition, the room's primary influence is in the transition region and below. Things were never simple in audio. At best there were temporary moments of peace between format transitions...

@tmuikku I apologize I'm quite busy but I will try to reply later. This topic is very significant for our understanding of perceptual phenomena in small rooms.

For 3, we have plenty of crossover into 2. Kii's new 7, Cabasse's Rialto, Devialet and most importantly Sonos. Unfortunately we know about their standards and science because we are obsessive nerds and hobbyists, not because of any significant effort on their part to inform their buyers. So we...

I would note that in controlled blind circumstances with fast switching, all the difficulties you mention fall away. In sighted circumstances... in other words normal circumstances, your ability to discriminate is lower. There's no getting around that. And I think most people conflate speaker...

Griesinger's term for the collapse of subjective clarity in concert halls, related to where you are in the hall, is "limit of localization distance". Critical distance is a purely physical ratio which has no subjective aspect. Much of what Griesinger has written about is not applicable to...

Beyond the "limit of localization distance". Critical distance is something else entirely.

Nothing unless the blocks happen to be very tall (think a few feet), which will change which room modes are excited.

So it's really a general question about headphone design? In that case, I couldn't tell you. The problem as I understand it is that headphone drivers are responsible for such a wide frequency range that HF commonly ends up showing breakup behaviour. Say you solve that, you still have seal...

I don't fully understand your goals From your first post. If the peaks/nulls are direction dependent and due to your ear shape, there is no problem and there is no cause to get rid of them. The "other inaccurate nulls" are the target, right? Looking at your in-ear results vs. coupler...

I would question how well you hear the peaks/nulls because the auditory filters/critical bands are broad in the kHz range. Frequency discrimination isn't very acute up there. Oratory1990 measurements of the Meze Elite using the GRAS ear simulator/coupler and two different pads do not show HF...

I think this raises a few central points. First is that all thresholds are averages and inherently assume variability. The papers investigating thresholds (for localization, see Blauert) experimentally show this in the data... it is very interesting to compare the various attempts to measure...

Consider them artefacts. If you measure with a probe microphone very close to the eardrum, they no longer appear. At least if I understood papers correctly. There is a compensation method developed by Etymotic for HF but it also requires probe measurements.

Only for 300Hz and below IMO using pressure-based absorbers. Other people will say use broadband, velocity based porous absorbers for various legitimate reasons, but I think they are generally unnecessary. Sure, but more important is in-ear measurement and correction rather than generic EQ...

Yes, exactly. I would find it hard to trust mixing decisions too if I used them as monitors.

I would add one more point from the mixing perspective: the imaging effects are unpredictable and room-dependent. For this reason alone I would avoid them.

Directivity, diffraction, "stereo".
