A review in Kloofy's link mentions the need for foam or rubber on the underside of the sink to act as a 'sound baffle' Presumably this is like the sheets of rubber often found stuck to the underside of stainless steel sinks to reduce any loud drumming noise made when water from the taps hits the bottom of the sink. If so, then my feeling is that the bowl of this acrylic basin is perhaps thinner and less sturdy than it might be. With a thicker and more robust basin, there wouldn't be any need for a 'sound baffle'.
