Ph.D. candidate in Architecture- Building Technology at the University of Michigan
Alaa is a PhD student in architecture at the university of Michigan. She is applying the Cymatic shapes in the diffuser that she developed and called "The Cymatic Diffusers". This has resulted in an outstanding performance that reduces sound defects such as echo. The diffusers were engineered based on a system called (Quadratic Residue Sequence) to control the angles of sound reflections from the diffusers to provide more homogeneously distributed sound instead of the focused (mirror-like) reflections that produce echo and build up noise. At the same time, by redirecting the reflected sound, the cymatic diffuser allows maintaining the sound energy in the room, and therefore reduce or eliminate the need to use sound reinforcement systems (i.e. microphones and speakers). It is an advancement of the methods used in some historical buildings to amplify sounds before the emergence of the sound system technology.
The Cymatic Diffusers requires no energy. And the sound diffuser resulted in a sustainable product that utilizes advanced technology that depends on engineering the shape to treat sound defects, allowing to use healthier and more sustainable materials and it is smart and simple to construct and use.
