What is the ruling on a man having sexual intercourse with his wife in the same room where their 8-year-old son and 15-year-old daughter are sleeping?

Among the etiquettes of intercourse is that a man should have relations with his wife away from the eyes and ears of people. It is disliked to have intercourse in a way that someone sees them, or hears their sounds, or to engage in intimacy in front of people, or for another woman to hear the sound of her sister's intercourse.
