You haven't answered much of anything, to be frank. In fact you started off by saying that my own ears and sound meters, on location, are wrong, but YOU are right and started telling me I need to do this and that. You have absolutely no place taking any manner of moral high ground here. So just...

Did you mention earlier that you've measured even less than 30 dB SPL there? In that same garden? If so, then that is pretty quiet indeed. It's in the very low 30's here now, inside, and it's as quiet as can be. It's obviously impossible to tell from that recording since I have no reference...

Apparently. But how exactly and what else affects things and how is not so straightforward. What kind of settings would you use for the SPL meter? A weighting? Or rather C? etc.? What exactly are you looking for when you measure something say, through a wall? Like I said, I wrote down many...

Yes. You assume the only issues that apply are "acoustic". That's not the case. Even you? Cheers,

That would be a bit difficult, but I feel like I have to stress this again: the point is NOT to keep outside sounds from leaking in. It's not even really the opposite, but almost, kind of. The point is simply, given a VERY loud, bassy, sound source (one hundred and ten decibels, 110 dB, Sound...

Why don't you explain what this is all about? What styrofoam??? I had a chance to simply TEST whether or not the "inverse square law" actually works in the meaning that you can make all the noise you want if anyone listening isn't right next to you (like in the city) but a bit farther away. And...

Yeah, I got the impression that you were talking about outside noise coming in only about 2/3rds through reading your post. That's a different subject altogether. After all, a rock band playing anywhere makes sounds decades in excess of one HUNDRED decibels SPL... so the first thing to do is to...

...o-kay? I thought I said the sound was reduced by tens of dB SPL. Measured with several types of sounds, from several different directions, several different distances. Tractors? What??? What are you trying to tell me, and why? I didn't mention recording as any part of this particular...

Yes indeed. Yes, the "different standards" are very true also from a purely scientific or empirical point of view. On a calm, quiet night if you go outside in the so-called countryside you can see the SPL meter stay in the 30's... something that's guaranteed to NEVER happen in any urban area...

Back to this... the log cabin in question, with no extra treatment whatsoever, provides sound reduction in excess of 35 dB looking from less than 10 metres away, and that's almost exactly straight through a large window on that side. ("Virtually zero sound attenuation"? I see...) My theory is...

I don't want to be rude either. But what are you trying to say? Some of what people are telling me here is that even with zero sound attenuation there would be no problem (loud sounds would not be heard). I am listening.

Yes. I think indeed most of the (technical) problem is related to the environment and terrain exactly. If it was on flat ground in the middle of a dense forest, there would be no problem to begin with, I suppose. But there ARE hills and lakes etc. involved. More precisely, right now I can only...

I kindly ask you to point to even a single instance in this thread where I have "rejected" something. I also ask you to point out examples of those "nonsensical" arguments. Because I don't see them. I say this very sincerely, whatever "nonsensical argument" you think I have used to reject...

Oh sorry, not an actual outer wall. There's a corridor behind it. Between apartments, instead of between rooms I guess is the proper distinction.

Interestingly, it does NOT ring "hollow" from the opposite side. So I guess there's insulation on one side only, and obviously not enough. It's also interesting that the hollow sounding side is plastered, with presumably the same plaster as the solid sounding wall next to it, and the total...
