Designing a resonant panel based on Helmholtz resonators with reduced geometrical complexity

Acoustics combined with digital fabrication has been investigated for multiple years. Most research in this area has focused on the combination of acoustics and additive manufacturing. This is mainly due to the ability of this technique to create any geometry, which allows for very high absorption. However, it has the downside that additive...

Towards Gridless Sound Field Reconstruction

Sound pressure varies over space and time. Knowledge about this exact behavior has many applications, e.g., room compensation, dereverberation and sound field reconstruction. Inside enclosures, the sound field is influenced by the surroundings, such as the geometry of the enclosure and the materials used.<br/>Reconstructing a satisfying sound...

Music in Heritage - The Acoustic Agora

Research about acoustics in heritage. In many of the redeveloped buildings, the acoustic quality is very poor. The reverberant times are very high due to the little amount of absorbing surfaces and some frequencies gain a higher G-strength then other frequencies. This is for a part due to the dimensions of the spaces. For example; churches with...
