HUG - here for all audio enthusiasts

INTRODUCTION- PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound, realisable by controlling the confounding variables between tthe microphone and the listeners' ears.

For example, the design of and interaction between the hifi amplifier and its speaker load can and potentially will alter the sound balance of what you hear. To reproduce the sounds captured by the recording microphones, as Harbeth speakers are designed to do, you would naturally select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

Identifying components for their system neutrality should, logically, start with the interpretation and analysis of their technical, objective performance, as any and every deviation from a measurably flat frequency response at any point along the serial chain from microphone to ear is very likely to cause the total system to have an audible sonic personality. That includes the contribution of the listening room itself.

HUG specialises in making complex technical matters simple to understand, aiding the identification of audio components likely to maintain a faithful relationship between the recorded sound and the sound you hear. With our heritage of natural sound, HUG cannot be really be expected to guide in the selection, approval, endorsement or even discussion of equipment that is intend to introduce a significantly personalised sound to the audio signal chain. For that you should do your own research and above all, make the effort to visit an Authorised Dealer and listen to your music at your loudness on your loudspeakers through the various electronics offered there. There is no on-line substitute for that time investment in a dealer's showroom.

If you desire to intentionally tune your system sound to your personal taste, please consider carefully how much you should rely upon the subjective opinions of strangers. Their hearing acuity and taste will be different to yours, as will be their motives and budget, their listening distance, listening loudness and listening room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you.

Alternatively, if faithfully reproducing the sound intended by the composer, score, conductor and musicians over your speakers is your audio dream, then understanding something of the issues likely to fulfill that objective is what this forum has been helping with since 2006. Welcome!"

    That sounds OK at first, but we know that the skin is reflective at audio frequencies and only up in the infra-red range is absorptive, where the wavelength is very short and can penetrate the skin - hence sunburn.

    If the high audio frequencies bounce off the skin, which organ or organs are detecting them?

    We know that even the very thin and porous grille cloth can and does effect the tweeter output at even 15kHz, and would have huge effect at 30kHz. A shirt, with it's completely closed woven structure would pass little through above perhaps 5kHz (a guess), so how a clothed body could be susceptible to super-high frequencies is a complete mystery.

      Did music really evolve as recent as 35000 years ago? Besides humans animals do make music. They must be doing that for millions of years. Birds sing and some birds go through certain ritual like dancing to court the opposite ***. The oldest flute made of bone is said to be 57000 years (or 35000). For humans to reach the sophistication of making flute must be later, i.e., after basic musical instrument such as drums. Why should humans be exception to the general rule? The oldest stone tool factory is 25000000 years old. Can music to be as old as that or as old as life itself? Humans must have heard birds singing millions of years ago and if they bulit factory millions of years ago then wouldn't they have discovered some sort of musical instrument or at least use their voice to repeat songs of the animals? In fact, the birds singing or other sound by howling wolfs may have exposed human to music millions of years ago. And those sound are without the 22khz CD upper limit.

      Maybe not the skin but how about hair fiber and hair follicle covering our skin and especially our head over the skull covering the whole brain. I am not sure but did anyone research of those possibilities? Insect uses the tiny hairs to detect vibration.

        Ok, I'm no anthropologist. I really can't add anythin more here. Whether the first instrument is 35,000 or 75,000 years ago is irrelevant. In our evolutionary development, music is an extrememely recent development and there has been insufficient time for our DNA to significantly adapt to that in perhaps as few as 1000 generations. An enhanced ability to play or hear music does not seem to have offered any irrisistible attractiveness to a mate, so has not been positively selected by evolution. It's as good as it needs to be.

        That's all I have to contribute to this thread.
