Weaving & Bonding - Acoustic Crochet
The experience of crochet enabled me to create a connection between the crochet structures and acoustics. And this connection led to the idea of making a space for music in which reminds me the particular moments of creation, failure and fragility.
Technique. The loop technique is using a single crochet stitch to navigate loops of thread through previously formed loops. It keeps the synthetic material pure, because it joins the thread without glueing. After untangling the crochet, the thread can be reused without any process. Stitches can be freely increased and decreased, 3D structures can be developed, and open non-slip webs can be created. The single thread technique generates no waste and can solve acoustics and tensile strength.
Acoustic. Dr. Bart Van Damme from EMPA concluded that crochet 3D structures can improve absorption in diffuse sound fields because the effective surface becomes larger. Prof. Kurt Eggenschwiler from EMPA furtherly concluded that a combination between absorption and reflection is possible, if the non-porous structure (front of the bubbles) is heavy and stiff enough (for singing 10kg/m2). To have an impact on low frequnces, a further reflecting layer (<15 cm) is needed (plexiglas 1,5mm).
Material. Form stability (pore control) and a high specific weight (1,37 g/cm3) encourage an interest in the use as a crochet 3D acoustic structure, where it performs as absorber and reflector (diffuser). The PES (Polyethersulfon) thread is made from many small threads and enables a flexible behavior, easily joining through the loop technique. The used thread is 20 mm.
Music. The delicate moments of making music becomes a place of matter and space gains a meaning. Introducing acoustic stools (Instruments designed by Denizay Apusoglu) and the piano, the proposed music space is a place where musicians come close and share the moment of joy and common feelings. The proposal space allows listening, rehearsing and teaching the music.
