When older buildings are being converted for new uses, it is always a challenging endeavor. If the conversion of that edifice is for musical use, it really puts your design skills to the test. Canisius High School in Buffalo New York made the decision to convert the century-old building into a fine arts center housing multiple rehearsal spaces, practice rooms and a small recording studio. AVL Designs Inc. was procured to provide acoustic design for the spaces. Many of the spaces were lower in height and oddly shaped, which definitely affects acoustics. It was important that we make the spaces sound larger than they actually are, so overhead diffusion was introduced. Diffusive canopies make rooms sound larger as well as evening out the response over the ensemble. Frequency specific absorptive panels were also utilized to balance the frequency response for the spaces, for each ensemble type.
