The length (time) of the IR depends on the sample rate (96 kHz in this case). When checking the ETC, you normally zoom in on the first 60-100 ms or so and with a dB scale of about 30-40 dB. The S/N ratio of measurements using noise instead of log sweeps as stimuli, will generally have a higher noise floor.
If find it peculiar that you again and again try to make it sound like you know what you're talking about when you clearly do not.
Jens, get real here. It was a simple question to NLP, just for clarification.
Empty room; Periodic shows a T60 of 10 sec and a poor S/N, while sweep has a T60 of 1 sec with a better S/N ratio.
Both the periodic and Sweep have no reflections and down -20 dB in a concrete empty bunker
. Jens, please zoom it in if you don't believe me.
I would not trust these measurment and sorry for saying this. Maybe there is a Limp mass absorber out there that works but I do have hard time to see this yet. Maybe it has to with the NLP strange measurements and lack of others as well.
DanDan has glorified these measurements as to make a point that the Limp mass works wonders. But I think he has to look over the measurments again.
There has to be more serious measurements first and then we can discuss if these limps is something to have.
