Hearing damage potential from metal dome tweeters?

Yes but i dont care a shiit about 85dB at 20khz i just dont hear it. Why this should pierce my ears?
I can only imagine it's bad for your ears at that frequency and intensity. But, give it a try ;)

Maybe i get deaf not so much in the science books to finde about. But at least i dont hear it. ;)

Just because the ear cilia no longer function up there doesn't mean it's harmless. Luckily, no sane music features that kind of treble.

What will the harm be?

I dont know how dangerous it is hearing 85db at 35khz. But one thing is clear if you like to archive 85dB at 35khz with normal music, you get your ears blown much faster with the lower frequence parts.

This could explain some of the 110dB listeners :facepalm:
 
I wonder if andysu would be kind enough to offer up one of his cats as a Guinea pig for the experiment...Who wants to volunteer to hold it during the test?

See lets imagine a good mic is already down a lot(a lot) at 35khz . Than even the best pickups are a lot(lot) down at 35khz. And digital ? 44khz sampling is a lot(a lot) down at 35 khz. No no need to care about 10dB up from a dome there.

Agreed. You won't get much past 20kHz from most material, because of the Nyquist filter if nothing else.

Whats leads us to the question is 80dB at 3khz more dangerous for the hearing than 80dB at 35khz? What i dont know.

Dunno. I guess if we get a cat to experiment on, we can find out!
 
The structure of modern digital broadcasting is good engineering, too.
I'm sure it is -- I wouldn't understand it, though.
I (barely) understand FM MPX -- and I still think it is very cool.

Ok you hold the kitty

While i calibrate the frequence generator? ;)
 
When listening to music with an average of 85 dB, any 20 kHz sound will not be 85 dB. Rather is 40 to 60 dB down from there.

Voodoless has already said everything necessary in the second post. Nevertheless here is a graphical version of it for easier understanding.

Normally one would set the said 85dB sound pressure level around 1kHz. Then the sound pressure level when listening to "normal" music at 20kHz would be lowered by 35dB on average.

In addition, every tweeter or widerange driver shows extreme beaming at 20kHz and even slight off-axis listening further lowers the sound pressure level of the sound arriving at the ear considerably.

Even with on-axis listening, the natural head movement when hearing music will ensure that the ear only temporarily captures the sound optimally at 20kHz (very likely even only a fraction optimal).

for a possible car audio application yesterday.
In the car, the head movement is even more pronounced (depends of course also on your skill level ;)) and it is very unlikely that you will hear the full range driver exactly on axis.
