Unit of pressure of N / m ^ 2 (Newton per square meter), which is Pa (Pascal) indeed.
Sorry, to late, you figured this out already.

How would you turn pascals into weights?
1 pascal = ? kilograms

On earth: 0.1 kg would create 1 Pa on 1 m^2.albert wrote:@badidea

Volume is a tricky one. The numbers on your amplifier volume dial are whatever they manufacturer liked printing. Better stay which pressure and force anyway.
Re: Squares
For the "Water Hardness" Formula:
Maybe you would take the density of water , and divide or mul it , by the wave speed ( 2300 centimeters a second ) ??
I'll play around , and see if i can derive a formula..

Re: Squares
You have to apply the formula, not just take the random example numbers for area and height that I chose.albert wrote:I think .5 Kg (4.9 Newtons) , is way to high for water hardness...
Water hardness , should be fractions of a kilogram.
Not that I see any relation between kilogram and hardness. They are completely different tings.
Re: Squares
To derive a formula:
I need to know Pascals per volume tick??
volume 1 = ? pascals
volume 10 = ? pascals
volume 15 = ? pascals

Re: Squares
What is a volume tick?
Just use a fast moving (pneumatic) cylinder if you want to create an earth quake (or at least annoying your neighbours).
A pneumatic cylinder can apply a pressure / force.

a "Volume Tick" is the notches on the volume knob of the stereo...
If volume 1 = 100 pascal
then
volume 2 should equal 200 pascal
volume 15 should equal 1500 pascal.
Not sure if it works that way or not...
So when i get the formula derived , you could say , "To earth quake the 4 inch wineglass takes voulme 10

Re: Squares
Yes, ask the manufacturer. They just mean loud, louder, loudest. Resulting in more power (in Watt) to your speakers.albert wrote:a "Volume Tick" is the notches on the volume knob of the stereo...
Re: Squares
The only relevant and also measurable value of sound is Sound-/Accoustic- Pressure.
Since it is "pressure" the unit of measurement, is Pascal/*Hecto-Pascal/Kilo-Pascal.
A Hecto-Pascal is equivalent to 1 Milli-Bar (1000 hPa = 1 Bar).
*Hecto-Pascal, aka: hPa is mainly used, to describe Atmospheric Pressure (Barometer).

Re: Squares
I think i get a method!!!
You take a speaker and place it over a bowl of water.
Then you gradually increase the volume until the water starts waving..
That would tell you the volume level of water , how loud it takes to move water.
You multiply that by the 4.68 hardness of of the wine glass.
And that should give you the volume level to make the glass earth quake.

Re: Squares
No, you won't this way, because you are again, mixing up things, that have basically
nothing in common (pressure of Air, then Glass filled partly with Water, which Btw.
reacts to a certain Frequency at a specified minimal Sound-Pressure).

@MrSwiss
Why wouldn't it work??
It's basically the same thing , as saying ? pascal , can displace ? milli-liters of water.
For the speaker on water, it should only take volume 2 or 3 to make the water ripple..
Then you mul that by the 4.68 hardness of the wineglass , should be between volume level 8 and 12..
Interesting Theory...
So for a diamond , it might take volume level 100??

Re: Squares
I expect that the water will start moving and the movement will depend on volume and frequency and the angle off the sound waves, but it is the complete story from water ripples to an earth quake that is 'shaky'.
Here is a funny YouTube clip (with a in water submerged speaker): https://www.youtube.com/watch?v=THUMdTohWkI or this one: https://www.youtube.com/watch?v=uENITui5_jU

The frequency doesn't matter... You just turn the speak on , to what ever station your listening to.
Start at volume 0 , and gradually increase it , until the water starts rippling..
That's the volume of water..
Then you mul that by the hardness , to get the volume level , to cause an object to earthquake.
