The future of ANSI/ASA S12.2 and room noise criteria

A working group is evaluating the American National Standard, "Criteria for Evaluating Room Noise" (ANSI/ASA S12.2-2019). This presentation will give an overview of our progress and areas of significant proposed change. The goal is to simplify the standard body so that the criteria reflect industry practice. Historical references and less common criteria will be relegated to annexes. Since the beginning of this standard, there has been interest in determining spectral imbalance, temporal variation, and the presence of tones. This talk will briefly mention proposals to quantify these aspects. Feedback from the industry is welcome to minimize the challenges associated with implementing this standard.
