be distracting because you’ll hear, directionally, what each speaker is producing
instead of feeling immersed in an atmosphere in which sounds occur naturally

reproducing the height plane of sound you would hear in a cinema, where the

Dolby recommends installation of four Dolby Atmos enabled speakers whenever

helicopter, passes overhead. Two of the speakers (whether they are integrated
