General Acoustical goals for single room tracking / mixing ?

Hi, Can you guys tell me a bit about what the measurable goals need to be achieved for a large room < 1000 sq ft that will be used for tracking and mixing rock and roll? Just in generality, what kinds of things are needed ? specific RT60 times, frequency response measured at different places etc? Thanks for enlightening me. Regards, John

some ideas to consider as a baseline before compromising: - Satisfies: Louden, Bolt, EBU, and IEC control room criteria - Background Noise: <= NC20 - ISD: >= 20ms - First Reflection: >= 12 dB down - Monitoring Level: 85db - Modal Distribution meets Bonello in 12 out of 13 1/3 octave bands - Frequency Response: +/- 6dB from 20Hz to 20KHz or better - Acoustical Symmetry: +/- 1db or better - Distortion (room): <= 1.5% - Isolation: >= STC 50 - RT60 (or equiv): 400ms for CR (+/- 100ms all frequencies), 400ms-2200ms for live room (variable) - Electrical Noise: none - Subjective: clear, excellent imaging, crisp, tight, quiet, no flutter echoes, good visibility, good workflow
