the pic u show is dampen noise by adding weight. not applicable to heavvy stone

That pic u show only work if in close space which is not applicable on yr case . Yr case just use a pelapik for all the tableware je lo

the noise u heard comes from the empty ceramic bowl.. not your stone top.

only solution can think of is u just put a rubber/silicone table mat on top of the table.

table mat or pelapik only is your best bet. Sound mainly gets reflected. You put that thing at bottom also no use. Plus it's not just sound from the contact between the counter top & the bowl. The bowl itself also emit/reverb within if its empty.

Ok, I just got my table with sintered stone.

My, it does sound loud if put something hard on it.

Like marbles hitting each other.

This is my experiment:
Bare, totally not covered
Alas Meja Transparent Extra Tebal'
Plate mat
Plate mat with texture.

Bare is 100% noise.
Alas Meja tebal, it reduces only a bit of noise, let's say noise is down to 80% max. Now the sound has a lower 'Thump' sound.
Added table mat on the Alas Meja, further reduce to about 70%

But most significant noise reduction, is when using a Small plate Mat which is textured / have some pattens on it / or groove. This one reduce the noise level by 50%.

My conclusion, anything that lays flat on the table, reduce the thump noise by a bit, but if added a texture mat, reduce by a lot.

Texture means not even. Like bamboo, or rubber mat with dimples, or decorative mats with Emboss on it.

I had tried this too, got some 3M sound deadening sheet pasted on the whole underside surface and it didnt help much. the problem is that these deadening sheet application is especially made to reduce vibration on thin metals, thus reducing the sound they generate. but sintered stone table top is around 1cm thick and is brittle throughout its whole thickness, it is like a thick sound generator.

I find it really is an unsuitable material for table top, gotten rid of it and am changing to a wood table
