Hey Johnnyb, did you do target shooting with a 22 ca. rifle when you were a kid -- without ear plus?? I did, and when I had a earing test some 30 years ago, the doc said I had a dip at around 4K or 5K Hz.

08-04-13: StringreenI think this is turning into an obsession for you. Bifwynne: Nope, I never did target shooting growing up. There was one instance when I was 18 and fired a 12 ga. shotgun just once. It's the only time I ever fired a gun. I can't remember if I wore ear protectors or not. My ear didn't ring or feel funny after I shot it. But if there was an instance that compromised my right ear, it was probably when I was 7, at a noisy children's convention and the kid next to me cupped his hands around my ear and talked directly into it in a loud voice. I could feel my eardrum shudder at the excess SPL. It could also be the narrow diameter of my ear canals. I can't wear any sort of in-canal earbuds, not even the expensive ones that come with varying diameter pads. And it's obvious when I try them that the right canal is narrower. |
Lew, others: There is no hidden level of complexity: Frank's genius created a design of exquisitely elegant simplicity. There's an explanation of the geometry in a post on another forum, not sure if the mods will allow the reference but here goes: previous post on diyaudio check post #222 for the geometry. |
Dave (Intactaudio), Totally concur with your last post. Patents are like locks: they help generally honest people remain honest by imposing barriers to temptation. They will not deter a determined burglar (or a deep-pocketed competitor). *** I'm with Johnnyb53 on the question of learned listening techniques vs. aural acuity (i.e. bat's ears). My hearing is less acute today at nearly 60 (yikes!) than it was at 20 or 30. Yet my ability to hear and understand music and sonics is greater and it continues to improve. Example: fifteen years ago I couldn't adjust SRA by ear, even in my own system. Today I can adjust SRA by ear in a resolving but unfamiliar system, even with an LP I've never heard before... in 2 minutes or less. My aging ears aren't growing more bat-like, my brain has learned what to listen for. The Sherlock Holmes metaphor was quite apt, IMO. In, 'The Sign of Four' (the first Holmes story), Holmes explains to Watson that he was quite consciously training his mind to improve specific skills needed for his chosen profession. In particular, he was honing his powers of observation and deduction by acquiring two things: 1. awareness of phenonomena he was likely to encounter at a crime scene; 2. knowledge of the sources of such phenomena. While Sherlock Holmes raw intellect was presumably well above average, it required specific training to make him a great detective. Contemporaries of equal or even greater intellect (e.g., his brother Mycroft) were inferior detectives because they had not developed and practiced the necessary skills. Another example would be the reputed 100 names for snow used by Inuits vs. the few names used by people who don't need such depth of knowledge about the stuff. The Inuits' senses are presumably no more or less acute than yours or mine, but they've trained their brains to a profound level of skill in an area of particular interest and concern. Likewise, the dedicated audiophile. |
Mark is right about the design's "exquisitely elegant simplicity." And this picture gives you all the clues on the design of its tangential guiding mechanism. _______ |
