1. A freestanding article of furniture comprising:
a) a plurality of structures having surfaces chosen from the group consisting of vertical, horizontal, angled and having horizontal and vertical components;
b) at least one of said structures consisting of at least one panel having (i) a said surface and comprising a first veneer with a pattern of micro-perforations extending completely therethrough, (ii) a sound porous core abutted behind said first veneer, and (iii) a second veneer abutted behind said sound porous core and having a pattern of micro-perforations extending therethrough, said micro-perforations of said first veneer acoustically connected to porous aspects of said sound porous core and to said micro-perforations of said second veneer, porous aspects of said sound porous core solely consists of a pattern of a plurality of holes larger in diameter than said micro-perforations, said holes extending from a flat front surface of said core through to a rear surface of said core, said holes being isolated from one another;
c) said micro-perforations having an average diameter within a range of from 0.25 to less than 0.65 mm;
d) at least one second veneer facing a storage space defined between said plurality of structures, said freestanding article of furniture configured to be located within a room whereby sounds within said room defined by soundwaves impinging upon said at least one panel are attenuated when they enter said micro-perforations of said first veneer; and
e) said at least one panel exhibiting enhanced sound absorption measured by increased Sabin values and reduced sound reverberation time as compared to a conventional furniture panel.
