Worked Solution & Example Answer:The owners have decided to convert an upstairs room into a family entertainment room - Leaving Cert Construction Studies - Question 9 - 2020
Step 1
Discuss in detail, using notes and freehand sketches, how each of the following contribute to reducing the transmission of sound in a dwelling house: completeness
Answer
Completeness in a building refers to sealing all potential gaps and ensuring airtightness throughout the structure.
-
Sealing Gaps: Small gaps around doors, windows, and other junctions can allow sound to leak in and out. Properly sealed blockwork joints and well-installed window systems significantly enhance the sound insulation of the dwelling, minimizing sound transmission.
-
Design Considerations: The overall design should lend itself to sound control, utilizing materials and construction methods that prioritize insulation.
-
Quality Craftsmanship: High-quality workmanship is vital to ensure that the structures are cohesive and complete, effectively contributing to the overall acoustic performance of the house.
Step 2
Discuss in detail, using notes and freehand sketches, how each of the following contribute to reducing the transmission of sound in a dwelling house: flexibility
Answer
Flexibility in building materials plays a crucial role in sound transmission reduction.
-
Absorbent Materials: Using materials such as acoustic mats or quilts in walls and ceilings helps to absorb sound rather than allowing it to vibrate through the structure. This can notably improve the sound transmission characteristics of a room.
-
Structural Discontinuity: Implementing structures that are not continuous such as staggered stud walls, which do not allow vibrations to easily transfer between different planes, further minimizes sound transmission.
Step 3
Discuss in detail, using notes and freehand sketches, how each of the following contribute to reducing the transmission of sound in a dwelling house: isolation.
Answer
Isolation in soundproofing focuses on preventing sound waves from traveling through different mediums.
-
Material Differences: Sound will travel through various materials; hence using different materials (e.g., rubber, acoustic barriers) in the construction reduces sound travel efficiency.
-
Wall and Ceiling Separation: Implementing a floating floor or staggered walls can help trap neutral air pockets which greatly lessen the sound transmission. This separation leads to better overall sound isolation.
Step 4
Using notes and freehand sketches show a revised design detailing that will reduce the transmission of sound through the stud partition and the existing first floor.
Answer
For the revised design:
-
Stud Partition: Construct a staggered stud wall with insulation between the studs to reduce sound transmission. Each stud should be staggered to minimize contact points and fitted with a sound-absorbent material.
-
First Floor Upgrade: Install an acoustic mat above the flooring to absorb impact sounds and provide a floating structure. Consider using two layers of plasterboard with staggered joints for additional mass, sealed tightly to prevent air leaks. Each component should maximize flexibility and minimize direct sound paths.
Step 5
Discuss two benefits that the sound insulation upgrades will have on the health and wellbeing of the occupants.
Answer
Sound insulation upgrades offer several health benefits:
-
Reduced Noise Levels: By decreasing noise pollution within the home, residents can experience lower stress levels and a calmer environment, significantly enhancing their mental well-being.
-
Improved Communication and Participation: Sound insulation facilitates private conversations without disturbances, allowing family members to engage in activities without fear of interrupting others, leading to a more harmonious family life.
