Objectives:
- acoustic phenomena and principles of sound transmission by air, liquids and solid material
- difference between different phenomena’s airborne noise and impact sound pressure
- protection against airborne noise and weighted normalized impact sound pressure level
- effects of mass and decoupling of layers of building parts on noise reduction
- examples for building parts and their sound reducing capacity
Method:
- lectures, exercises, workshop
Theory:
- lectures, charts, presentations …
Practice/Task:
- working groups with 3–4 participants working on detail examples
- finding sound reducing values for different building parts
- examine building regulations for acoustic measures
- compare measured straw building components with regulations valid in your country
- calculate specific weight of building parts (wall, roof) per m² as indicators for good or bad acoustic performance
- calculate density of straw bales …
