This study set out the terms of reference for my thesis about finding the design strategy of sound-based architecture. Architecture changes the effect of sound in the space like a musical instrument. The activities in the space also respond to its sound, bringing different acoustic experiences to the space.
In contrast to the logic of traditional construction, digital fabrication offers the opportunity to produce non-standardized elements that have the potential to create spaces and installations with specific acoustic properties, while using digital tools to think about the possibilities of acoustics for people. In addition to the possibility of producing a single, non-repeating sound element, digital fabrication opens up the limits of acoustic boundaries and how space is occupied, creating differentiated acoustic properties within that field.

Design Flow
Motivation
In the development of architectural acoustics, acoustic design is often adjusted in the existing architectural space. Most of the spatial acoustic design is not a reference basis for the initial design, and architects often lack the knowledge and design methods in acoustic design.
Frequency to the Geometry
By using Pyaudio, the length of the pipe will affect the frequency of the sound. By sorting out the different sounds and their corresponding pipe lengths on the Frequency Chart.
The acoustic pipe begins to aggregate as the clusters from a single individual, and different frequency groups begin to follow the mesh distribution on the plane, with limited interconnection and interaction. When the aggregation spread out on the field, it depends on the context of the environment.
When the pipe clusters are aggregated into the field, the height of these pipes controls the respective sound frequencies, but at the same time also controls the sound direction when the heights link together to become a surface. This surface can be thought as a diffuse surface and become an alternating sound direction method.
Pipes Triggering
The different triggering arrangements, and how they changed the experience, by triggering different clusters in the field, and the order of the timing for generating the sound will also be crucial.
In Iteration, trying to see pipe aggregate in different forms and shapes, those shapes will also be related to the surrounding how people received the sound, and what kind of spatial feeling it can bring.
About Site
Nikolaj Kunsthal was a church originally called St. Nicholas Church, it is one of the oldest churches in Copenhagen, the Church turned into Contemporary Art Gallery and the function of the church is not being used anymore. The concept of the project is by studying the pipe organs as a part of the building, and turning it into an urban soundscape, from interior to exterior; private to public, with organs that only play on a certain time to a daily base. A place to experience different sound experiences and scenarios.
The inspiration for the distribution of the pipe geometries. Discreet Music Side B . Three Variations on the Canon in D Major by Johann Pachelbel’ featuring the Cockpit Ensemble takes up side B and sees the musicians repeating brief excerpts from the score but with slight changes every now and then plus added alterations.
Air Supply
Air capacity simulation will be based on each pipe's volume and the airflow distance it traveled, air pressure will also be controlled by the size of the pipes, in the upper and ground layer of the pipes the connection end will be opposite which help the sound to spread in the space.
3D Audio
In Unreal engine the sound file imported in, but the sound file itself won’t have any spatial data for the sound itself, the sound attenuation and sound occlusion will be assigned in sound cue, which give the spatial characteristic to the sound file, and the environment set up will let the sound passively changed by the environment. With sound generate from the pipe the sound cue will need to assign individually to the object, and the frequency change will base on the length of the pipes.
