No idea, but I am using acoustic treatment , which is very effective. This is designed to provide excellent sound absorption while enhancing the decoration of any room. Designers are free to choose from a large variety of fashionable fabrics.
In agreement with others above, my vote goes for...
Acoustic insulation, but don't jam it in tight. Needs to be loose to work.
As heavy/dense a boarding as you can go, or multiple layers.
For best performance don't hard-join to the walls. Mastic as per @Pagey. Just needs to be air tight.
I planked my dining room ceiling many moons ago. It's 19mm thick but narrow boards so not to painful to fit, though I still made myself a board lifter as I was solo.
For soundbloc on ceiling, you need a board lifter (cheap on ebay and re-sell it, or hire). For 15mm soundblock, you'll also need a priest and a chiropractor.
Fireline should also work as it is more dense, double board it.
Always use quality acoustic insulation roll for better result. Acoustic insulation roll has a quilted polyester wool absorber towards the noise source to both block the sound from escaping and to absorb the sound that is reflected.
