Question: 1 / 400

What design consideration minimizes sound transmission between spaces in a property?

Using larger windows

Using single-pane glass

Extending walls to the ceiling

Extending walls to the ceiling is an effective design consideration for minimizing sound transmission between spaces. When walls are built from the floor to the ceiling, it creates a continuous barrier that helps to reduce the passage of sound. This ensures that noise from one room does not easily transfer into another, promoting a quieter and more private environment.

In contrast, other design choices such as using larger windows or single-pane glass may actually increase sound transmission, as glass surfaces can allow more sound to pass through compared to solid materials. Incorporating more doors can also lead to sound leakage unless they are well-sealed and designed specifically for sound attenuation. Therefore, extending walls to the ceiling provides a much more effective solution for soundproofing in any interior space.
