book
Table of contents
Tammo's and Herman's Index. An introduction by Manfred R. Schroeder
Chapter 1. The roots of the STI approach. Tammo Houtgast and Herman
J.M. Steeneken: Introduction - Our first effort - Introduction of STI - Speech envelope spectrum and MTF - Further developments - Envelope modulation and the ear
Chapter 2. Basics of the STI measuring method. Herman J.M. Steeneken and Tammo Houtgastective measuring
methods for predicting speech intelligibility - Measurement and calculation of the STI - Overview methods, test signals, and calculation constants - Interpretation of the STI value (subjective measures) Diagnostic features, some examples - Speech and test signallevel adjustment - Application examples. Chapter 3. Improvements of the STI method: frequency weighting, gender, level dependent masking, and phoneme specific prediction. Herman J.M. Steeneken: Introduction - Reconsideration of frequency
weighting functions - Signal-to-noise ratio dependency of the frequency weighting - Level-dependent masking - Phoneme group specific weighting functions - Validation - Conclusion and future developments.
Chapter 4. Limitations of the STI method. Rob Drullman: Introduction - Distortions of the modulation transfer

Impaired. Joost M. Festen and Reinier Plomp: Introduction - Simple versus complex hearing versus complex hearing impairment - Trade-off between noise and reverberation for listeners with hearing loss - Syllabic compression in hearing aids - Speech reception in fluctuating noise
Chapter 6. Implementation of intelligibility algorithms into acoustic simulation programs. Wolfgang Ahnert: Intelligibility measures used for comparisons - Application of intelligibility measures in EASE4.0
Chapter 7. Development of an Accurate, Handheld, Simple-to-use Meter for the Prediction of Speech Intelligibility. Kenneth Jacob, Steve McManus, Jan A. Verhave and Herman J.M. Steeneken: Introduction - Speech Transmission Index (STI) considerations - STI-pa an efficient form of the Speech Transmission Index method for public address
and sound reinforcement systems - Embedded system vs. general purpose
