Did you have to add additional room damping to compensate for the added reflective surface?

Binaural recordings cannot duplicate the HRTF functions of each individual listener. During your whole life your brain is learning to translate the comb filtering caused by each of your body parts to determine positioning and space. The construction of the headphones does not restore that function.[/quote] Nice word salad, but the fact remains that HRTF is only an attempt to digitally replicate the binaural experience using ordinary stereo recordings. A binaural recording is made quite differently from ordinary stereo as you should know. It replicates a person sitting in front of the orchestra and how that performance would sound. Our brains can process that experience with headphones as though the person was actually there. Very cool! Here is but one example of a binaural recording "head." https://www.bhphotovideo.com/c/product/ ... 4AQAvD_BwE |

As you know, Tom went to great expense to get his special audio room and has paid attention to every detail. Of course his chrome dome can have an impact on the the acoustics. Therefore in the interest of obtaining absolute system performance within the confines of the "perfect" listening room he contracted for a special accessory. A special foam an-echoic hat to wear while listening to his favorite tunes.

It is a physical phenomena of your body that drives how each individual determines spacial clues. It happens in real life with everything you hear. Binaural recordings use a dummy head to provide a pseudo HRTF that cannot match individual HRTFs because each person's body is different causing different comb filtering. However, using a recording that did not try to create a generic HRTF by using a dummy head and then applying it to algorithms that are experimentally determined for each individual, a closer approximation of the true space can be achieved than with a dummy head. |

Some engineer has had too much time on his hands. I expect it is a "what if" thing that instead of improving the playback, it will put too much "crap" in the signal path removing any semblance of musicality. |

Not some engineer, but a lot of engineers and scientists worked on HRTF's. There have been dedicated test chambers built to provide measured individual data. Lots of articles in the AES Journal about HRTF's over the years. |
