Split for "problems with dress extreme features"
(Quick note: physical isolation from noise helps your listening experience but doesnít improve signal to noise ratio. Signal to noise ratio refers to the amplification + source end of the chain, itís a measure of electrical signal vs. electrical noise, not the physical noise you hear from the outside environment)
I didn't mean signal to noise ratio in the electrical sense, but effectively, acoustic isolation will help increase the actual quantity of (desired signal)/(unwanted signal). I was using signal to noise ratio as a figure of speech. As to the relative frequency response of the headphones, who is to say what is accurate? What is the reference? Hi-fi gets to be more of an art rather than science or engineering when subjectivity is invoked. BTW, have you tried headphones from Shure or Etymotics? The Shure's were my first choice, but Bay/Bloor Radio did not carry them, nor could I find them elsewhere in Toronto. Mind you, I use my Sonys with an iRiver IHP-120, which does not pack significant output power, so I don't know how they respond at higher power levels. Ideally I would imagine that the headphones should be evaluated for frequency response across the entire audible spectrum from minimum input signal power to maximum. Of course, this will also be dependant upon the amplifier characteristics including saturation, total harmonic distortion etc. But that is getting much too involved.
Well, I grossly overestimated the mass of my head and so the finally amount of force my head would sustain if I fell off a bike was an insane amount. This convinced me to always wear a helmet during bike rides, but my TA grading my homework wrote next to my answer, "How big is your head?"
That is quite funny actually. I notice that many people find it hard to estimate the weight of various body parts. I once had an exgf claim that just one of her breasts weighed approximately 11 po
unds. Unfortunately we never got around to verifying that. That figure sounds highly exaggerated to me. Perhaps she meant the pair of them combined, which sounds much more reasonable. If so, I feel very sympathetic to the poor souls who have to bear such burdens. Lets all give them a helping hand ;)
