Worked Solution & Example Answer:The accompanying sketch shows two semi-detached houses - Leaving Cert Construction Studies - Question 9 - 2007
Step 1
Using notes and freehand sketches, show two design details that would increase the sound insulation properties of the first floor in order to minimise the transmittance of sound.
Answer
Design Detail 1: Floating Floor
- Description: Create a floating floor system with additional layers of sound-absorbing material that decouple the floor from the structure.
- Explanation: This method improves sound insulation through the principle of Flexibility, allowing the floor to absorb sound.
Design Detail 2: Insulation Between Joists
- Description: Fill the spaces between timber joists with an acoustic insulating material, which is covered by a secondary layer of flooring.
- Explanation: By integrating additional insulation materials, we enhance the Completeness principle, reducing gaps and improving overall sound absorption.
