Convention Paper
Design, Construction and Testing of a Large Recording and Postproduction Audio Facility
AES Convention 93 · Paper 3410 · October 1992
Abstract
This paper discusses the design theory; construction implementation; and acoustic testing of the largest recording complex to be constructed during 1991-92 in New York City-JSM Music, Inc. The recording complex involves very low NC levels; high STC ratings between rooms due to the inter-client nature of the room usage. The paper will discuss: 1) Detailed wall construction profiles and measured STC results, data peculiar to the multiple usage programming of certain acoustic spaces, resulting in unusually high STC values for these systems; 2) HVAC design and measured NC levels for major acoustic spaces; 3) The use of an acoustic ray trace software (CART-Computerized Acoustic Ray Trace) showing the various proposed designs and, of course, the final solution for the control room and major studio rooms; and 4) Measured energy time curves (ETCs) and resultant RT60s for certain critical acoustical spaces.
