Church Acoustics Measurements and Analysis
The measurement of Reverberation Time (RT) is a quite important estimation of the sound quality in a closed environment. From this measurement, in fact, one can gain information about intelligibility of signals and amount of reflection energy. In particular the liturgical hall of a church is an interesting environment because of its relevant volume and the materials adopted for the interior des...
متن کاملNonminimum-phase equalization and its subjective importance in room acoustics
This paper investigates the perceptual significance of residual phase distortion due to an approximate equalization of the nonminimum-phase room response from a sound source to a microphone in a reverberant room. It is shown that disrupted phase relationships introduced by a minimum-phase equalization filter may have a detrimental effect on perceived sound quality. The subjective assessment of ...
متن کاملObjective and Subjective Measurements
Three dimensional user interfaces can help users in time-critical situations to improve their ability to solve problems. But they also may distract them from fulfilling their tasks with efficiency and effectiveness. This requests to control and limit the distraction caused by usage of those interfaces. Therefore it is necessary to measure and compare distraction caused by three dimensional user...
متن کاملSubjective Evaluation of Auralization of Physics-based Room Acoustics Modeling
This paper describes the results of subjective evaluation of auralization by listening tests. The task was to compare real-head recorded and auralized sound samples. The evaluation process as well as the creation of soundtracks are briefly reviewed. The listening test procedure is presented along with the analyzed results of a case study. They show that with a simple room geometry (a lecture ro...
متن کاملFootwear Cushioning: Relating Objective and Subjective Measurements
Foot-ground interfaces exist in many different forms. Frequently the interface is a shoe or floor mat, and sometimes it is a carpet-like material, such as an Astroturf, providing specific biomechanical characteristics to help one perform effectively. Hence these interfaces can play an important role in improving functionality or performance, preventing injury, and reducing discomfort. Human mov...
