Когда две трубы немного расходятся, по звуку он начинает слегка пульсировать.

Сейчас заиграют чистые тоны, чтобы вам было лучше слышно.

Вот волна частотой 261 Гц, а вот волна 263 Гц.

Если они зазвучат одновременно, начнётся интерференция компрессионных и рефракционных волн.

Иногда они сходятся в максимумах, и звук получается громче.

Иногда максимум приходится на минимум, и звук смолкает.

Частоты отличаются на 2 Гц, поэтому раз в секунду дважды можно услышать более громкую ноту.

Такой вот эффект биения.

Сейчас их должно быть хорошо слышно.

Переведено и озвучено студией Верт дайдер.
