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 ...
متن کاملSubjective Sound Quality evaluation of SACD compared to CD
Using a high quality sound reproduction system and listening to SACD recordings compared to the same CD recordings, show significant quality differences between these two digital formats. In short: the high segment of the frequency range is much more fluent and open and natural sounding in SACD. Also the dynamic loudness range is larger in SACD. The profoundness and deepness of the bass-region ...
متن کاملSound Quantity and Quality of Sampo 3065 Combine Harvester
ABSTRACT- Noise is considered as one of the most debilitating conditions in farming operations. In this study, a number of factors affecting the noise generated by Sampo 3065 combine harvesters were evaluated. Factors were engine speed and gear ratio for combines with and without original cabins. A factorial experiment arranged as a completely randomized design with four replicates was used. Re...
