From the look of the current market you may think the headphone train is moving along pretty fast. Well, you ain't seen nothing yet. The photo above is a very high speed exposure of the pistons in a new engine that's about be be hooked up to the front of that train...and it's already running at very high RPM.

Given the glimpse of what's coming down the tracks by engineers at the Audio Engineering Society Headphone Conference, my overwhelming impression walking out the door is that we're about to see a revolution in headphones.

Oh my, this paper sure throws a wrench into my mental monkey-works.

In it, Gunther Thiele opines about how to develop the standardized EQ and signal processing needed to deliver a tonally neutral headphone listening experience for audio professionals. There are some very interesting tid-bits of information here...but the conclusion will be somewhat troubling for headphone audio purists.

Most papers presented were pretty esoteric stuff—interesting, for sure, but not necessarily practically informative for enthusiasts. I found the following papers had information that was more directly relevant for enthusiasts.

Most of the papers presented at the conference were technically impressive and intellectually challenging, but, for the most part, not unexpected. There were a few, however, that were completely unexpected on my part. Here's three surprising and interesting papers.

The image above shows an organized set of words used in sensory profiling to describe subjectively sensed audio. More about the "Sound Wheel" in this article.

Sensory Profiling is the study of how we experience things....headphones in this case. There were many papers on the subject, here's a few just to whet your whistle.

In order to make augmented reality audio on headphones believable, individualized HRTF measurements must created and used in the signal processing of the headphones. Typically, HRTF measurements are taken in an anechoic chamber with dozens of speakers around the room, or speakers swept by mechanical arms, or with rotating stools for the subject to sit upon. Obviously, you're not going to install these systems in every Walmart across the country so millions of kids can enjoy an immersive game of Pokemon Go.

You're no doubt aware of the latest Pokemon Go craze. Kids walk around with smartphone in hand searching for these little cartoon characters that have been virtually placed in the real physical world. It's hot, hot, HOT!!!

Well, when the kids are crazy about something, the MBAs take notice. If you can enhance Pokemon Go by making it a more "real" experience, the kids will by your stuff. As a result, companies from Sennheiser to Microsoft to Nokia to Apple are all in a race to make headphones sound like real sound that come from outside your head.

Having done my Google maps satellite surveillance prior to the event, my hotel was a quick 100 meter walk from the Nordkraft building in which the conference was held. This old power plant building was refurbished in 2009 as part of a cultural development effort in the surrounding waterfront area.

A few of yesterdays papers on perceptual evaluations referred to the "Sound Wheel" developed by Delta's SenseLab---a Danish firm that offers an audio product testing service. I was intrigued at first simply because it was colorful and pretty. After the sessions I looked it up and found it was far more than that.

It's always a bit Twilight Zone to travel for 20 hours only to arrive at your destination at 9 o'clock in the morning. I walked up to the desk clerk at the Aaborg Hotel to check in.

"I'm sorry, sir. Your room won't be ready until about 2 PM."
