Shiftdagi karnaylarning asosiy vazifasi ommaviy eshittirish tizimlarida, fon musiqasini ijro etishda va yong'inga qarshi eshittirishda foydalanishdir. U tovushni kosmosning har bir burchagiga teng ravishda uzata oladi, aniq va baland ovoz sifatini ta'minlagan holda ma'lumotlarning aniq aloqasini ta'minlaydi. Misol uchun, savdo markazlari, maktablar va shifoxonalar kabi jamoat joylarida shiftdagi karnaylar muhim rol o'ynashi mumkin.
