Hi,
I've been browsing about infrasound and its effects on the human body and brain.
It would seem that today's better subwoofers are getting into serious near-infrasound territory at levels which affect mood and intellectual performance.
Infrasound has been used for centuries in large cathedral organs to give a spiritual lift to the congregation. Religious feelings can run high when the human being is exposed to the output of the longest pipes. 32footers produce 16Hz at considerable dB(A)s.
These low frequencies can have strange effects on people exposed to them. Feelings of elation, sorrow, cold, heat and nausea are known responses.
Anyone care to speculate on the effects of regular doses of 100+dB @ sub-20Hz on the average audio/HT enthusiast? If not on occasional bumps and bangs from DVD films then why not on music? Repetitive doses of high level infrasound over extended periods anybody? Ever felt unexpectedly elated at loud, bassy rock concerts?
The near religious zeal of the SVS clubmembers may actually have a basis after all. We're not crazy. We're just hooked on near-infrabass induced highs!:b
You think this sounds crazy? Hitler's lot used infrasound at specific frequencies to enrage the crowds prior to his mad race hatred rantings.
HT enthusiasts refer to feeling tired or "drained" when they've been listening at reference levels. Even on short (well known) bass effects chapters. It is addictive isn't it?
My 16-46 PCi reaches 15Hz. 10dB above the musical background thanks to room gain! No wonder I'm grinning when I listen to Satriani at a steady 100dB on the meter! No wonder others sometimes feel I exagerate the physical effects of listening at these levels. Could this be the reason I feel compelled to share my enthusiasm for SVS?
