Saturday, April 26, 16:30 — 18:00 (Estrel Hall B)

T4 - Speech Transmission Index (STI) Measurements in Practice

Presenters:
Peter Mapp, Peter Mapp Associates - Colchester, Essex, UK
Ben Kok, BEN KOK - acoustic consulting - Uden, The Netherlands

Abstract:
The Speech Transmission Index is today the most widely used international measure of potential speech intelligibility. In particular it is cited and performance requirements are incorporated in many national & international sound system and emergency sound system / voice alarm system standards and codes of practice. Few standards however state how STI performance should be measured and the equipment required to carry out such measurements. The workshop will discuss measurement techniques, data analysis, measurement equipment (including smart phone apps), equipment calibration, and the capture and logging of measurement data. The workshop will be given by Dr. Peter Mapp, a leading authority on STI measurement and the current chairman of IEC 60268-16—the International Standard relating to STI.
