Publication bias in organizations such as AES is unlikely to be an issue in this field, since much of the discussion (on this forum at least) is around results published by manufacturers themselves, such as the KEF paper referenced earlier.
Thanks for the defense. I would hope by now that it was not necessary. Let me add:
Over the years I have received several awards for my published research. All came from large international organizations populated by Harman competitors, so it is clear that this is not a "company" or "brand" thing. This is from my current bio.
"For his scientific contributions to the audio industry he has been recognized with:
• Two Audio Engineering Society (AES) Publications awards (1988, 1990).
• The AES Silver Medal award (1996).
• The AES Board of Governors Award for service to the society (2003).
• CEDIA Lifetime Achievement award (2008).
• Beryllium Driver Lifetime Achievement award from ALMA (Association of Loudspeaker Manufacturing & Acoustics International) (2011).
• The AES Gold Medal award (2013).
• Inducted into the Consumer Technology Association Hall of Fame (2015).
• The Peter Barnett Award from the Institute of Acoustics (UK) (2017).
He is a Fellow and Past President of the AES, a Fellow of the Acoustical Society of America and a Fellow of CEDIA (Custom Electronic Design and Installation Association)."
So, it appears that the scientific knowledge has value in the eyes of Harman competitors. It is all published, in the public domain. Whether a company uses the published knowledge in their product development is up to the company. Several do, but not all of them admit it, probably because it detracts from the image that they alone are responsible for how their products sound. Others do admit it, and a few are even proud that they know about the science, use it, and have benefitted from it. My book is not just about my/NRCC/Harman research. It is a summary of relevant science from many international sources.
The reality is that there are very few commercial or academic organizations with the money, time and facilities to perform serious research in this area. Loudspeaker companies are generally busy designing new products. These may or may not contain genuinely new technology or knowledge, but the scientific publication route is available to share and publicize such information.
As I have said elsewhere, the foundational research work done at the NRCC was funded by the Canadian government and I was employed as a research scientist. I and the measurement facility I created were used by several Canadian and US loudspeaker companies because of the lack of commercial bias. I travelled internationally lecturing on the scientific material to professional organizations and to individual loudspeaker manufacturers. As a consequence of that success I was invited to move to Harman as Corporate VP of Engineering. That Harman approved my request to set up a corporate research group independent of the brands, and allowed the publication of all findings was a truly remarkable thing. Many companies would not have done this. Several million dollars have been spent over the intervening 27 years providing facilities for state-of-the-art technical measurements and unique subjective evaluation rooms incorporating positional substitution hardware. Included was an educated staff - not inexpensive.
So, here we are in this forum, with a Harman brand that makes use of the research knowledge displaying evidence that it works. Any manufacturer who chooses to display accurate and reasonably comprehensive anechoic data on their loudspeakers is able to join the discussion. A few already do this. I don't recall seeing any statement that Harman/Revel is uniquely capable of designing neutral sounding loudspeakers. The knowledge of how to do it is published in numerous AES papers and in my books - and in summary form in this and other AVS forums. See the attachment to my post #220
