Floor-to-ceiling glass is not typically used to enhance the acoustics of a room. While glass can contribute to the aesthetic appeal and openness of a space, it tends to reflect sound rather than absorb or diffuse it. This reflective quality can lead to increased noise levels and echoes, making a room feel louder and less comfortable acoustically.

In contrast, techniques like using soft furnishings, sound-absorbing materials, and strategic layout are widely recognized for their ability to improve sound quality. Soft furnishings, such as carpets, curtains, and upholstered furniture, help to dampen sound waves and reduce noise levels. Sound-absorbing materials, such as acoustic panels or insulation, are specifically designed to minimize sound reflection and enhance sound clarity. A strategic layout can also play a crucial role in controlling acoustics by arranging furniture and other elements to optimize sound flow and reduce disruptive echoes.
