Realistic question - Breaking the threshold?


Recommended Posts

I've been pondering this for a while. The threshold of our atmosphere is 194 db. 20 years ago people thought 160's were impossible, 10 years ago 180's were impossible. Since cars are doing mid 180's does anyone believe that a 194 + is possible?

Honestly I believe that they will plateau around 190db, and if I am correct isn't this around the point when you can visually see shock waves.

A "sound wave" is different than a "shock wave"

a concussion blast is extremely loud but doesn't act like a sound wave.

how high will we get? with more power, better woofers, and building knowledge on burp cars I'm sure it will end up loud as shit.

Right, but sound produces pressure and pressure can produce a shock wave.

Im sure they'll get close, 194 db is only the threshold for sustained sound, an instantaneous pressure pulse could go much higher, say an nuclear warhead.

Like we think being heard a mile away is loud but when krakatoa erupted in 1883 it was heard 3000 miles away. Thats pretty much thought to be the loudest sound on earth so far.

well they finally got a new meter that will read over 180db more accurately and can read over 183db. Which people have been bitching for years the TL is not accurate over 180db and needs to be updated.

Thats why Hal Shocker just hit 185db about a month ago

I would not call any scale actuate because all them say something different but they are there just to give you an idea

194 represents a perfect vacuum upon rarefraction.

So NO, we will never be able to REPRODUCE sound at that level and beyond since sound does not exist at that level and beyond.

Unless

We do it in water.
