Standards Deep Dives
ANSI/ASA S12.60 Complete Guide: American Classroom Acoustics Standard
ANSI S12.60-2010 is the American standard for classroom acoustics, specifying maximum RT60 (0.6s), maximum background noise (35 dBA), and minimum STI (0.60). Here is every requirement explained with calculation examples, compliance methods, and how it compares to BB93 and DIN 18041.
BB93:2015 Complete Guide: UK School Acoustics Standard
Building Bulletin 93 (BB93:2015) sets the acoustic requirements for all school buildings in England and Wales. It specifies RT60 limits, background noise levels (BNL), and sound insulation — all mandatory under Building Regulations. Here is every requirement, room type, and compliance method.
IEC 60268-16 Complete Guide: Speech Transmission Index (STI) Standard
IEC 60268-16:2020 defines the Speech Transmission Index — the definitive metric for speech intelligibility in rooms. Here is every aspect of the standard explained: the STI calculation method, STIPA measurement procedure, quality scale, and how building codes worldwide use it.
ISO 3382 Complete Guide: Room Acoustics Measurement and Parameters
ISO 3382 is the international standard for measuring and evaluating room acoustics. Part 1 covers performance spaces, Part 2 covers ordinary rooms, Part 3 covers open plan offices. Here is every parameter, measurement method, and requirement explained — with the specific clause references you need for compliance documentation.
WELL v2 Feature 74 (Sound) Complete Guide: Every Requirement, Threshold, and Compliance Path
WELL v2 Feature 74 has three parts: Sound Mapping (RT60), Sound Barriers (background noise), and Sound Masking (speech privacy/STI). Here is every threshold, every space type, every measurement condition, and the compliance pathway for each part — from precondition to optimization.
