His research focused on the assessment of the subjective perception both in architectural and environmental acoustics. In the following, a summary of Daniel de la Prida’s research (mostly focused on room acoustics) is given. All the […]
Soundscapes: A perceptual design tool on the rise
How we perceive the sounds around us is dependent upon their inherent acoustic characteristics but also their associated meanings, context and our experience. We individuals shape the frame of reference. Exposure to unwanted, negative sounds (noise!) impacts our quality of life. Until now, our primary goal in acoustics has been to solely reduce the negative […]

Understanding a room’s natural vibes! Eigenfrequencies and eigenmodes of a reverberant chamber
Juan Negreira, our Concept Developer at S-G Ecophon Spain, explains in this video what the phenomena of resonance and eigenmodes of a room are. Likewise, he exemplifies the concepts by means of a simple experiment carried out inside the reverberant chamber of Lund University (Sweden). A structure (either solid of fluid), due to the fact […]
