Background & Aims: Noise is one of the most important harmful elements in industrial environments causing auditory and non-auditory disorders. One of the non-auditory effects of noise is reducing efficiency and production quality. The aim of the present study was to survey the effects of exposure on selected sound pressure levels in performing skill tasks. Materials & Methods: In the laborat...

One approach to improving sound quality is to create a preference map on the basis of several acoustic parameters relevant to auditory perception. The map is derived from several stages of subjective testing, acollstic analysis, and auditory modeling. The multidimensional scaling technique CLASCAL reveals common perceptual jimensions shared by sets of sounds samples, perceptual features specifi...

This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of methods, and integration of science and art. The main tools to investigate the mediating relationship of people and environment through sound ha...

This keynote introduces various contributions to a structured session on sound quality organized by the present author. In the last decade, basic research as well as practical applications of sound quality increased substantially. This holds true for sound quality of emissions e.g. in product sound as well as for sound quality of immissions e.g. in the environment. For product sound, two cases ...

Wixom and Todd (2005) integrated the user satisfaction and the technology acceptance literatures to theorize about and account for the influence of the information technology artifact on usage. Based on Wixom and Todd’s integrated model of technology usage, we propose the 3Q model by investigating the role of service quality (SQ), in addition to system quality (SysQ) and information quality (IQ...

The quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. This acoustic quality can be characterized based on the reverberation time (RT), speech transmission index (STI) and the sound insulation. In this context, an acoustic study was conducted in an auditorium located in the Higher...

Introduction: "Joubert syndrome" was first introduced in1969. This syndrome is a rare genetic disease with autosomal dominantpattern. Hypotonia, ataxia and motor delay of the disease known as clinical manifestations. In the few reports of this syndrome, mostly functional and structural components studied and radiographic images such as speech and language developmental delay symptoms has been l...
