As far as I'm aware the original purpose of the forum was to discuss research papers from the AES et al and the mission expanded organically from there.
I think you're correct in that there isn't any written definition of what the forum is about; however de facto it is about using the scientific method, part of which is backing claims with evidence. And that evidence should be valid i.e gathered with some controls and a thought- through methodology.
I think questioning any findings or current paradigms is encouraged here, provided it is done within that framework. What isn't welcome is the 'I own both DACs and they certainly sound different, don't tell me what I can and can't hear' type of contribution.
At a minimum, posters should accept that their perception is not flawless and their subjective experience is not, therefore, sacrosanct.
Intersting that a search of the AES database shows that Psycho-acoustics are well documented and are part of the AES remit.
Like most things in life, there are rarely any definative boundaries to what is or isn't.
Audio Engineering Society (AES) researches how human perception interprets sound—covering, masking, and, loudness—to improve audio production, speaker design, and, 3D audio,. These studies guide, engineers in, creating, realistic, soundstages, by, manipulating, frequency response, off-axis, response, and, spatial, characteristics,.

Key Psychoacoustic Areas in AES Research:
- Spatial Hearing & 3D Audio: Research focuses on how humans localize sound and perceive height, crucial for immersive audio and virtual reality,.
- Speaker/System Design: Studies emphasize creating a "holographic" soundstage, optimizing sweet spots, and managing room acoustics through psychoacoustic principles,.
- Data Compression & Modeling: Psychoacoustic models analyze audio signals to determine masking thresholds (what the ear cannot hear), allowing for reduced data rates in compression,.
- Subjective Evaluation: AES investigates how listeners evaluate sound quality, looking at metrics like loudness, roughness, and sharpness,.

The AES E-Library provides extensive papers on these topics, including studies on
psychoacoustically optimized loudspeakers and general,
sound engineer applications.
