Acoustic tiles can be quite effective in modifying/improving the acoustics
of a room - that's what they're really for. I can't really see something
light enough to stick on a ceiling being much use in cutting down noise
transmission, unless it's just high frequency which is unlikely. Before
spending money, I'd want chapter and verse in their claims for this.
