Axiom Home Page Forums General Discussion Stereo Maximum SPL at 1kHz

C'mon, you know you want to...

You probably could listen.....




once.

JohnK, the wattage being consumed here is by a single tone.
Add in another several thousand and the power usage may climb.

The numbers put forth by the speaker are impressive, but then again, i have never seen equivalent specs posted on any other brand either.

Chess, the SPL level would determine the power usage, regardless of the number of individual tones which combined to reach a given SPL.

16,000 or so tones managed to reach a Db level of 110 several times during the hockey game here in Edmonton tonight.

Ok, I haven't read this thread yet and am shamelessly plugging my hockey team. Ignore me and play on through.

I was thinking in more simple terms John where a hump or dip in a frequency response will produce a different dB level compared to the dB with the same power given to the 1kHz; but yes it makes sense that the overall sum of SPL would total that of the highest dB at whichever frequency that may be.
The sum dB of all frequencies are not additive and cumulative otherwise our ears would be in big trouble.

Right, chess; e.g. 90dB+90dB(of the same sound)=93dB, etc.

Now could you imagine additive and cumulative sound?
90dB + 90dB from only TWO frequencies equating to 180dB!!!!
(Disregard the fact that the dB scale is not a linear one).

So the math, at 1kHz with x power input we have 90dB.
At 500Hz with x power with a dip in the response of -2 dB we have 88dB.
At 3kHz we have a peak of +4dB over 1kHz, thus 94dB (for that tone).
What is the total SPL of the three?

instantaneous or averaged?

Nope, not even once. I want to keep my hearing!

Wonder what sort of ear protection is used when measurements like that are made?

When I go to the NASCAR races, I take the soft, rubber earplugs that you can buy at the drug store. I think that they knock off 20 dB of the sound.
