A double-studded wall is specifically defined as a wall that is constructed with two vertical studs placed side by side. This design is implemented to increase the strength and stability of the wall, as the presence of additional studs allows for enhanced weight-bearing capability and reduces the likelihood of warping or bowing under stress. This feature is particularly advantageous in applications where extra support is necessary, such as wall sections that will bear heavy loads or when constructing taller walls.

The other options refer to different types of wall designs or constructions that do not align with the specific definition of a double-studded wall. For example, insulated blocks pertain to energy efficiency, while grooves for electrical wiring describe a different structural concern. Advanced soundproofing technology relates to sound isolation techniques, which, while important in construction, do not specifically define the presence of double studs within a wall structure.
