van Eijk, Jordy (author)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...master thesis 2023
