Hey i found this article that talks about how to create an optimal environment for learning. It's kind of technical, but basically it says to promote learning use room dividers to create sound barriers.

Both PTs and educators agree that sensorimotor development is foundational to learning in children. Children with sensorimotor delays may not spontaneously move and explore their environment. In order to facilitate sensorimotor development in these children, PTs may recommend adaptive toys, adaptive positioning and/or environmental modifications (eg, natural versus fluorescent lighting, use of room dividers or sound barriers) to promote optimal learning through movement and exploration in the classroom environment. A study by Miedaner and Finuf15 found that adaptive positioning improved the performance of children with neuromotor impairment in areas such as speech intelligibility, upper-extremity function, head control, and pulmonary function, which supports the principle of how development is interrelated across domains of growth and learning.
