PURPOSE This study examined the head orientation of young children in naturalistic settings and the acoustics of their everyday environments for quantifying the potential effects of directionality. METHOD Twenty-seven children (11 with normal hearing, 16 with impaired hearing) between 11 and 78 months of age were video recorded in naturalistic settings for analyses of head orientation. Report...

Numerous studies have shown that teachers often speak louder in classrooms because of the acoustic properties spaces. To improve acoustics classrooms, it is necessary to develop relevant criteria. Existing evaluation scales for parameters room been developed on basis adults a variety languages (e.g. Dutch and English). One issues still not fully recognized effect respondents’ language age resul...

Noise reduction is often essential for cochlear implant (CI) recipients to achieve acceptable speech perception in noisy environments. Most noise reduction algorithms applied to audio signals are based on time-frequency representations of the input, such as the Fourier transform. Algorithms based on other representations may also be able to provide comparable or improved speech perception and l...

A distortion-weighted glimpse proportion metric (BiDWGP) for predicting binaural speech intelligibility were evaluated in simulated anechoic and reverberant conditions, with and without a noise masker. The predictive performance of BiDWGP was compared to four reference binaural intelligibility metrics, which were extended from the Speech Intelligibility Index (SII) and the Speech Transmission I...

This study presents the retrofit acoustic dq1esign of Italian theatre “Cavallino Bianco”. In its historical configuration, hall had a curved roof with pressed-plant fiber ceiling, which was demolished and replaced wooden without false leading to an increase in volume worsening reverberation time. proposed realization wave ceiling application sound-absorbing reflecting panels on walls, have alre...

The overall aim of the four experimental studies included in this dissertation was to investigate the influence of background speech on writing performance. In Paper I, a manipulation of speech intelligibility of background speech, by using the Speech Transmission Index (STI), revealed disruptive effects at lower STI values (i.e. with relative low speech intelligibility) than expected, based on...

In the context of forensic phonetics the transcription of intercepted signals is particularly important. However, these signals are often degraded and the transcript may not reflect what was actually pronounced. In the absence of the original signal, the only way to see the level of accuracy that can be obtained in the transcription of poor recordings is to develop an objective methodology for ...

Two significant spaces define the soundscape of worship in a church: chancel and nave. The is space with primary function sound source, where preachers choir are often seated during church services. Church design layout have changed throughout history based on functional needs its target congregation. Some modern churches omitted to fit contemporary aesthetics. main aim this study investigate r...

Transmission dynamics for sexually transmitted infections (STIs) exhibit a large degree of heterogeneity, much of which has been attributed to behavioral variability. However, because STI transmission concentrates among individuals who frequently change sex partners, immune responses also are likely to contribute to the heterogeneity in STI transmission dynamics. We review both theoretical and ...
