TLDR
This paper will review the development of Schroeder diffusers over the last three decades and suggest solutions to overcome the limitations of the original concepts.Abstract:
Schroeder diffusers revolutionised the design of scattering surfaces when they were invented in the 1970s. For the first time diffusers with defined acoustic performance could be easily designed. Since their inception, much has been learnt about the performance of the surfaces. Limitations of the original concepts have been studied, and solutions found to overcome many of these. This paper will review the development of this technology over the last three decades.read more

Metadiffusers: Deep-subwavelength sound diffusers
TL;DR: These sound diffusers are rigidly backed slotted panels, with each slit being loaded by an array of Helmholtz resonators, to present deep-subwavelength diffusing surfaces based on acoustic metamaterials, namely metadiffusers.

A qualitative study of young women's experiences of recovery from Bulimia Nervosa
TL;DR: Women's ability to recover from bulimia nervosa and take control over their lives is based on their self-efficacy, and effective care should strive to strengthen women's beliefs in their own abilities, to instil hope for recovery and thus to bolster their Selfefficacy.
Investigation of the acoustical and airflow performance of interior natural ventilation openings
TL;DR: In this article, the authors present a Table of Table of the Table of contents of this paper. But, the Table is not complete, see Table 2.2.1.

TL;DR: In this article, a quadratic residue metadiffuser is used to control sound diffusion at very low frequencies, and the experimental results reported in this paper are in close agreement with analytical and numerical predictions.
Dissertation
Volume diffusers for architectural acoustics
TL;DR: In this paper, a 2D volumetric diffuser is investigated, considering a number of design concepts; namely arrays of slats, percolation structures and cylinder arrays.

The Fractal Geometry of Nature
TL;DR: This book is a blend of erudition, popularization, and exposition, and the illustrations include many superb examples of computer graphics that are works of art in their own right.
