When we have modern call center cubicles and they are very close to each other more in an open space, there can be a lot of noise and not only from people talking but also from chairs moving, typing the keyboard, printers, computer noises, etc; therefore a certain type of partition panel is recommended to isolate noise. To the medium or high panels you can place thick carpets to absorb the sound, you can also place a certain type of absorbent ceiling. Another way to hide and avoid noise is to place strategically located bookcases, books absorb noise as well as wood.
