ARCHITECTURAL ACOUSTICS DESIGN LAB
Gary W. Siebein
Fall, 2011 3 credits
This course will consist of lecture presentations, seminar discussions, readings, a field trip to an auditorium and support spaces, and discussions on the acoustical design of theaters and performing arts spaces. Class work will consist of student design work on an actual building project consisting of the tasks usually undertaken by a professional architectural acoustics consultant. This is a project-based course. There are no tests. Schematic design plans of a project as developed by an architect will be provided by the students or instructors. The project will include an auditorium with 600-1200 seats, ancillary support spaces, music rehearsal spaces and other necessary rooms. Students will work individually on all phases of the project. Each student will work through the following items with an emphasis on exploring acoustical issues.
1. Establishing acoustical design goals for each of the spaces in the building.
2. Acoustical design of the auditorium and other acoustical spaces using reverberation time analysis, space shaping by ray diagraming and model studies (either water, light, computer and/or physical models can be used).
3. Developing initial design studies for the project including plans, sections, perspectives, models, etc. as required.
4. Schematic design of a sound reinforcement system for the building with a concept statement, single line diagram showing equipment and connections and a specification in Masterspec or other standard format.
5. Analysis of sound transmission loss and impact isolation requirements for all construction assemblies used in the building. This will involve estimates of octave band transmission loss for wall and floor assemblies, selection of assemblies to use and details at critical connections. 6. Analysis of mechanical noise produced in the building and selection of design strategies to achieve
the required attenuation so low noise levels are maintained in the auditorium.
7. Preparation of an initial report with goals and schematic design recommendations for each item above.
8. Preparation of a final report including a review of the actual construction documents for the project to insure that all acoustical design features have been included in the bid documents. Specific work assigned for the entire semester is summarized below. The instructor will make a brief presentation each week (approximately 1-2 class periods long) to review material and outline the process for the subsequent week’s work. Work for each week will be reviewed individually and in groups after the presentation. This is a lot of work. It must be done on a weekly basis. Progress submissions will be
Attendance is required. The course grade will be based on the quality of the submitted final product (35%), participation in class through discussion and presentations (10%) and preparation of assigned work (10 submissions at 1% each =10%) and interim grades on work in progress (3 interim submissions - Room acoustics 20%, noise control (15%), and Construction Documents review (10%).
