When installed along the bottom edges of floor joints, resilient furring __________ reduce the sound transmission between adjoining floors.

The correct answer is the term "channels." Resilient furring channels are specifically designed to decouple the drywall (or other surface materials) from the structural framing. This decoupling helps to minimize the transfer of sound vibrations between adjoining floors, effectively reducing sound transmission. Channels create a gap that absorbs sound energy and reduces its capability to travel through the building materials, which enhances the acoustic performance of the floors.

While strips, blanks, and panels also play roles in construction and sound insulation, they are often used for different applications or do not specifically have the same sound-dampening properties provided by channels. Strips can refer to a variety of materials used in construction; blanks often relate to solid materials used for filling gaps; panels are typically solid surface materials. Therefore, channels are the most effective choice for reducing sound transmission in the context provided.
