Process

Ideation & sketches

Panels

• Panels are 15x15cm each
• Modular and combinable
• Different textile techniques
• Variation in density and thickness
• Ecru color (white)

Room Divider

• Display of 32 samples. If time does not allow for 32 different samples, simple felted panels will be used in place
• 8x5 tiles
• Video Mapping of shapes of each tile using TouchDesigner. The mapping will respond to the frequencies in the room, that will be tied to a color.

Testing Box

• ~~2 chambers one for microphone, one for speaker~~
• ~~Panel sample in between the chambers, inserted by a gaskett (frame)~~
• UPDATE: I have abandoned the testing box and will instead choose a nearfield test for time and material optimization.

Design & Fabrication

once you start designing and fabricating your first tests, you can link both at the bottom of the page with footnotes

"This step of the process was important because i learnt to draft my own pattern digitally. The first tests of this can be seen here on the right, find half- or test-fabrication files here¹"

Increasing felt thickness - Compression Laminate

Since I am doing all felt panels by hand, I wanted to optimize for time using the felted pieces I had and joining then together to make thicker pieces. The obvious choice would be needle felting them together but I felt like trying something similar to compressed laminate wool.

I created a rice starch paste to use as "glue" in between the layers.

Prototypes

prototypes are your first step towards shaping your final piece, product, material et cetera

Testing

Standard Octave Bands (ISO 354): Measurement of sound absorption in a reverberation room

Frequency	Description	Situation	Why test
125Hz	Deep Bass	Subwoofers, thunder, trucks	Low-end absorption baseline
250Hz	Bass	Male voices, bass instruments	Room modes, bass traps
500Hz	Low-mid	Male speech fundamental	Critical for speech
1000Hz	Mid	Female speech, instruments	Critical for speech
2000Hz	High-Mid	Consonants, cymbals	Speech intelligibility
4000Hz	High	Sibilance, air noise	High-frequency absorption

Mentoring notes

Mentors in all sessions may share with you their comments, notes, advise, projects and technical equipment to check out. This is good place to share those, so that you can find them later on when you need them the most!
