Hello,
I'm wondering what influences the "not reliable" parameter for RT60 measurements. I'm testing some panels, and am noticing that while testing the empty room, RT60 measurements are rarely labeled as "not reliable", but with panels added, many more values are flagged. The sweep is fairly loud (I had it even louder for "treated" measurements), so I doubt it's the noise floor.
I know RT60 measurements don't really apply for small rooms... If that's the reason for the unreliable measurements (pushing the Schroeder frequency lower), I would really appreciate a bit more detailed explanation, especially if I can improve reliability in some way.
Thank you!!!
