Working Group on Weighting Networks and Band Pass Filter Sets
Chair: ASA Standards
Scope: Develop and maintain standards for the specification and performance characteristics of fractional octave bandpass filters and the design target specifications of weighting networks for acoustical measurements. Liaison with the corresponding IEC and ISO standards groups. Coordination of the US vote on related or parallel international standards.
Responsible for the following published standards:
- ANSI/ASA S1.11, Part 1 (IEC 61260-1) – Octave Band and Fractional Octave Band Filters – Part 1: Specifications
- ANSI/ASA S1.11, Part 2 (IEC 61260-2) – Octave Band and Fractional Octave Band Filters – Part 2: Pattern-evaluation Tests
- ANSI/ASA S1.11, Part 3 (IEC 61260-3) – Octave Band and Fractional Octave Band Filters – Part 3: Periodic Tests
- ANSI/ASA S1.42-2020 – Design Response of Weighting Networks for Acoustical Measurements
