1. Introduction When listening to a lecture in a large auditorium it is often difficult to understand the speech. Among other factors, comprehension may be impaired by reverberation, which is sound reflecting from the wall, interfering with direct sound. Based on the modulation transfer function (MTF), the speech transmission index (STI) has been proposed as an objective measure for speech inte...

Speech variability in groups of speakers with Parkinson's disease (PD) and with Friedreich's ataxia was compared with healthy controls. Speakers repeated the same phrase 20 times at one of two rates (fast or habitual). A non-linear analysis of variability was performed which used some of the principles behind the spatio-temporal index (STI). The STI usually employs variation in lip displacement...

the main objective of this study is to find the prevalence, level of knowledge, and mode of transmission of reproductive tract infection (rti)/sexually transmitted infection (sti) among evermarried females in uttar pradesh. to study the various socio-economic and demographic factors responsible for rti/sti among married females. this study is based on data extracted from district level health s...

Over the last 5 years a computer prediction model based on a web browser has been developed, www.whyverne.co.uk; first to predict sound levels in rooms, followed by early decay time and reverberation time. Now Speech Transmission Index (STI) can be calculated for many identical sound sources in any type of room with or without noise control. Comparisons of sound propagation and early decay time...

current standards for indoor comfort are based on studies of adults, but they also apply tochildren, even though children differ in terms of metabolic rates, clothing types, activity levels, and preferences in space arrangement. children are also more sensitive to a range of environmental factors, they are usually unable to interact with their environment, and they accept indoor conditions pass...
