Discrimination of 2D wall textures by passive echolocation for different reflected-to-direct level difference configurations KU Leuven
In this work, we study people's ability to discriminate between different 2D textures of walls by passive listening to a pre-recorded tongue click in an auralized echolocation scenario. In addition, the impact of artificially enhancing the early reflection magnitude by 6dB and of removing the direct component while equalizing the loudness was investigated. Listening test results for different textures, ranging from a flat wall to a staircase, ...
Introduction to Human Echolocation: a way of seeing the world even for visually impaired people KU Leuven
Preliminary study on the estimation of just noticeable differences of spectral dips and peaks by adaptative method KU Leuven
The presented work is intended to supportthe evaluations and decisions on taking or discarding possible measures to improve acoustical situations, by assessing the audibility of moderate to small spectral changes. The approach is based on listening tests in which pink noisebasedsounds with and without spectral peaks and widths with variable contrast and width are presented.Throughout the test, the degree of contrast is varied adaptively in a ...
Proposal For Reversable Intervention to Historical Monument, By Means of Room Acoustic Simulations KU Leuven
The historical building “House of Silence” (17th century building) in Egenhoven, nearby Leuven (Belgium) has been already for more than 70 years recognized as a protected monument. In 2011 has this mansion become the property of KU Leuven with a promise on preservation of the spirit of the domain. Several acoustic problems, related to sound insulation and sound reverberation, have been identified by the new users. It is well known, that the ...
