Abstract
This report covers the design process of a master thesis project with the aim of
developing concepts for diffusers. Diffusers are objects that have the ability of
spreading the sound energy evenly in a room. The diffusers were to be suitable for use
as interior objects in “ordinary rooms” (schools, hospital wards, and offices). The
diffusers should, through their aesthetic expression, attract architects, and provide
possibilities for spatial design. A method for the creative process called Double
diamond was implemented. The field of acoustics was researched, focusing on
diffusion. Benchmarking was done, and interviews with potential users and customers
were conducted. Ideas were generated, then evaluated.

This report covers the design process of a master thesis project with the aim of
developing concepts for diffusers. Diffusers are objects that have the ability of
spreading the sound energy evenly in a room. The diffusers were to be suitable for use
as interior objects in “ordinary rooms” (schools, hospital wards, and offices). The
diffusers should, through their aesthetic expression, attract architects, and provide
possibilities for spatial design. A method for the creative process called Double
diamond was implemented. The field of acoustics was researched, focusing on
diffusion. Benchmarking was done, and interviews with potential users and customers
were conducted. Ideas were generated, then evaluated.
From the idea generation, five concepts were selected for prototyping. One concept,
Recycled, showed potential, but was not chosen to be prototyped. The Recycled concept
is based on pressing or molding solid diffusers from recycled materials, or end-of-use
absorbers, and could be incorporated into the majority of the other concepts. The raw
aesthetic expression of this concept could signal honesty, and sustainability, which
could be profitable for Ecophon. The concept has potential for further development, as
a separate project.
The fullscale prototypes were mounted in a room, and the acoustic parameters speech
clarity, and reverberation time were measured. The results showed an improved speech
clarity, and reverberation time, for all prototypes. The prototype called Paper folds
preformed the best. Two of the prototypes, Sheet & Beams, and Layers generated test
results that were difficult to interpret. However, all of the final concepts have the
potential of being adapted to suit the Ecophon product range, and were recommended
for further development. (Less)
