Acoustics of Four Large Viennese Halls

Architectural Acoustics: Acoustics of Concert Halls II

Some high-resolution direction-of-arrival DOA estimation methods, such as the MUSIC method, have been developed based on vectorsensor array. However, these high-resolution methods suffer from serious drawbacks. Indeed, they are not able to estimate coherent signals and sensitive to calibration errors. Mainly to overcome these limitations and in particular to satisfy practical engineering applic...

Lecture Halls - Room Acoustics and Sound Reinforcement

This paper describes our experience with lecture halls with regard to the room acoustics, sound reinforcement and audio frequency induction loops for persons with hearing impairment. The optimum reverberation time and geometrical conditions for classrooms are well known. Recent research basically confirms this knowledge but indicates the need for shorter reverberation times. However, many exist...

Acoustics of new and renovated chamber music halls in Russia

In recent years several classic halls for chamber music were renovated and a few halls of similar capacity were built in Russia. We have selected the most interesting ones and measured their acoustical parameters. Here we are presenting detailed descriptions of five halls in Moscow, Tula, Ufa and Penza in combination with the measurement data. Some of them have long reverberation time and their...

Acoustics of concert halls with organs in Russia: trends and problems

Acoustics in School Sport Halls and Its Implications for Physical Education

Due to the demanding acoustic conditions in physical education lessons and the related problems with health and academic success, the aim of this study was to examine the acoustic conditions of teaching in sport halls in Slovenia. Thirtyfive sport halls were selected, reflecting four types of school sport halls grouped according to the period of their construction. The reverberation time was me...
