I bump into Terry trying to explain to Eric something about Re: Car Audio?
TS> venues. +5/-20 wouldn't
EF> Wow... a 25dB spread! Wouldn't that just sound HORRIBLE?
TS> Yes, but not unusual. I'm sure you've noticed what some idiots do
TS> with consumer Eq's with +/- 12 or 15 dB ranges. Some wannabe
TS> pseudo-pros too.
Yes, but there is nothing we can do against theses except to organize
special teams that would go into every house and correct any such
problems. Highly improbable! ;)
EF> speaker could have BOTH thoses specs listed, but 40-16 +/- 1dB is a lot
EF> more precise and less misleading than 20-20K +/-3dB!!
TS> Few speakers really approach those specs over their coverage patterns
TS> and in real space. High end electronics you might spec tighter. Pro
TS> tape specs should be better than that, while consumer ones (including
TS> corssover) might spec at -20 cutoff.
Once again my discussion isn't about speakers that will output 40-16K
+/- 1dB, but with the terminalogy and clarity of the specs themself!
TS> But the B&K reps can have good stories. They try to make accurate

TS> normal audio mics.
Yes, and on the other hand we have Peavey, Yamaha and ... who produce
microphones! Go figure...
TS> 15-130 dBspl would be ideal IMHO. Occasionally I've even been in a

TS> Most transducers distort enough at the high outputs so that I'd rather

I wouldn't want to hold my ears in pain while listening to it! I was
tracking this week-end in a small apartment with headphones. God it was
loud, I took breaks every 15-20 minutes to make sure I wasn't over
taxing my ears. I have two more weeks like that and can't wait for it to
be over!
TS> Sonalysts sound stage in Waterford, CT beats the Universal Studios
TS> noise floor. (It's also able to offer military secure facilities, SGI
TS> paint boxes, sound track composition, etc.). Also, one studio I built
TS> if you turned off the mechanicals.
I don't know why I asked where, probably because i wished I was there!
Though I still be curious to see what kind of noise level we get in
sensory deprivation booths!
