Please cite that research. I'm sure that psychoacoustic professionals would love to hear of work in direct contraction to nearly a century of published research to the contrary. >adds to presence and realism There is NO content in human speech below 80 Hz. All that spectrum consists of microphone defects (breath pops, mechanical noise) and room noise. >(the sense you're not listening or talking to the world >through a 1940's telephone set) and contributes to improved intelligibility >in certain consonants, especially among male speakers. FALSE! As a consultant in the design of sound systems for large and small public spaces for 25 years, particularly spaces with difficult acoustics, this is something I've had to learn a lot about. :) The science in this area is not new, and it's been quite well understood for half a century. 73, Jim Brown K9YC Fellow Audio Engineering Society Member Emeritus Acoustical Society of America ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
