Full anechoic chambers aim to absorb energy in all directions. Semi-anechoic chambers have a solid floor that acts as a work surface for supporting heavy items, such as cars, washing machines, or industrial machinery, rather than the mesh floor grille over absorbent tiles found in full anechoic chambers. This floor is damped and floating on absorbent buffers to isolate it from outside vibration or electromagnetic signals. A recording studio may utilize a semi-anechoic chamber to produce high-quality music free of outside noise and unwanted echoes.
Famous quotes containing the word chambers:
“Why rather, sleep, liest thou in smoky cribs
Than in the perfumed chambers of the great,
Under the canopies of costly state,
And lulled with sound of sweetest melody?”
—William Shakespeare (15641616)
