ASSIGNMENT

5 Final Assignment

DUE DATE

15/05/2025

For your final assignment, you will use all the tools and knowledge you acquired during the semester to improve the acoustic conditions of an existing room.

The room in question is the Model and Design workspace of Raplab (HIL B61). It is a multipurpose room that is used for lectures and as a workspace for model building. When used for lectures, the speaker is usually at the corner of the room, next to the projection screen, and the students are sitting in rows in the middle of the room. The big worktables are pushed to the back of the room to make space for the chairs. When used as a workspace, all chairs are stacked and placed at the back of the room, and the tables are grouped in pairs and placed in the middle of the room, leaving room around them for people to sit and walk (see photos).

Find attached the 3d model of the room in a Rhino8 file.

Your task is to:

  • Analyse the room and its acoustic conditions. Use the balloon method and the online reverberation time calculator to determine the RT60.
  • Describe its current acoustic conditions, and see if it meets the SIA norms (spoiler: it doesn’t).
  • Propose acoustic treatment solutions that improve the acoustic conditions of the room and align with how it is used. Justify your interventions and use any of the tools you learned during the semester to do so.

Collect everything in a post on the course’s website, and prepare to present your work in class on the 15th of May. You will have 5 minutes to present and 5 minutes for Q/A.
