Acoustic Shell Design – Optimized design through wooden structure and acoustic simulation

Since the past, acoustic design has made a lot of progress, and in modern society, it is possible to predict and design sound diffusion or reverberation time through computer simulation.

In the past, acoustic architecture created an optimal acoustic space in the form of a space, whereas in modern times, the optimal shape and space are created through simulation, and reflectors and sound-absorbing materials are placed in appropriate locations to create an optimal acoustic space.

In this plan, we will try to find out whether it is possible to have an effective sound effect in a space made of wood structure by utilizing 'wood' currently used in various acoustic spaces.

The sound diffusion, which varies depending on the shape of the space, is planned through a wooden structure made of wood, the main material of the sound structure.

The wooden structure itself becomes an object with sound effects.

Plan the depth of the waffle and the reflection panel in the shape of the shell through the distribution of reverberation and sound pressure according to the concert hall stage and auditorium position.

On the stage where reflection is required, the depth of the waffle is lowered so that reflection can be concentrated, and the part where the negative focus phenomenon occurs is planned deeply so that sound can be absorbed inside the structure.

A parametric wooden structure having a free form according to acoustic analysis is exposed in a concert hall, so that the structure becomes a sound absorbing agent and a reflector.

This design, which started from the idea of boldly exposing the wooden structure by using the acoustic characteristics of wood and relating it to the sound, analyzed the sound according to the shape, grabbed the shape of the shell, and unraveled the shape into a wooden structure.

In addition, a feasibility study was conducted through the Rhino Grasshopper simulation process, and it was found that it is relatively effective.

However, due to the nature of the acoustic space, it cannot be further developed unless the space is actually created and experienced and analyzed.

The conclusion in this plan does not end with the simple wooden structure showing the beauty of the structure, but I hope that various plans come out by approaching the nature of wood.
