Any soft furnishings will help -- drapes, a mat by the french doors, upholstery.

Add 2 soft stationary drapery panels left and right of the door. And at least one beautiful decorative rug.
Anything fabric in at least 2 areas will help

Try full, lined curtains on the doors and their windows. Matching curtains or Roman shades on the window over the sink. With the unique shape, it will need to be custom. You can try taping some quilted fabric to the window glass with blue painter tape temporarily. The more fabric, the more absorbent.

Add a large rug near the bar stools and a long wide runner in front of the doors and windows. Put cushions on the bar stools.

In the long run, you may want to add acoustic panels on the ceiling. an acoustic specialist can give advice and make the calculations for you.

I don't know what is behind the photographer.

it won't help the dog, but wearing soft soled house shoes... like moccasins... will cut down a lot of clatter. unload the dishwasher onto a dry towel, too, instead of directly on the counters.

we have a very 'acoustically lively' vacation home, these are a couple habits i've taken up.

I think drapes...... it would be a great addition for your perfect kitchen!

Nice big soft dog beds will absorb sound, too.

I echo what others above me have said. I would put up fully lined drapes so that when you open them, you can still look our your French doors and windows. A rug runner or two will also help immensely. I have two in my kitchen and it does help with the noise plus it's much more comfortable than standing on tiled floor in bare feet!

Beautiful kitchen! I'd HATE to cover those windows with ANYTHING. I'm no expert, but perhaps the combination of so much tile, glass and the vaulted ceiling are the culprits? I would love to have seen a warm wood floor :(

Applepieorder's idea of a long runner in front of the doors/windows and under the chairs would help, it would also warm up the room visually; it seems a bit cold now. And maybe chairs with upholstered seats and backs too? dunno...

Acoustic panels: would hate to ruin the look of the ceiling, but we can't see it, but not a bad idea to try asking an expert.

Best wishes; keep us informed if you find something that works.

Lastly, I too have noticed lately that some things/voices just seem louder to me. Weird....

Thanks for all the comments. I don't want to add drapes unless I have to. I love the view! I will try the egg crate idea and add some throw rugs and see where that gets me. Thanks again for all the ideas!

A pad and tablecloth on the table would also help.

OMGOSH, solraven is brilliant if that works! I NEVER would have thought of it but it makes SO MUCH SENSE. PLEASE post if you try that and let us know if it works. LOVE your kitchen. And I understand about the dog - I have EIGHT!!!! tiny dogs and their barks can pierce an eardrum...

Are you able to coat the concave part of the ceiling with some acoustical stuff like they use commercially to reduce noise?

Would wood floors have been quieter? I'm surprised to hear that. Wood and tile are both hard surfaces.

Remember that the drapes can be stationary panels and not even be used to block Any of the window and your view...only to obsorb sound....hang them so they hang just along the edge of your windows that are flanking the French doors. You can also add stationary Roman shades over your sink...they are like a faux shade that doesn't go up or down.

Thanks BoerneCheryl! :) I've always noticed the "coziness" that a carpeted room brings in the form of dulled sounds. I'm in FL, where tile is the most common flooring. I love the beauty and durability, but also wanted the coziness.

I started off w/ the obvious choices, rugs, drapes, etc. I got the idea from one of my classes. The room was about 400 sq/ft, with 12' ceilings, yet there was absolutely no echo in the room. I realized it was because of the walls which were fabric acoustic panels. So I said to myself, "Hmmm... acoustic foam is just thick eggcrate foam. Why not?!" Then I thought about all the places that I could hide it. :)

Add a rug under your table and a runner in front of your sink.
