How would you describe laughter that is uncomfortably loud and harsh?

The term "raucous" perfectly captures the description of laughter that is uncomfortably loud and harsh. When laughter is described as raucous, it conveys a sense of roughness and discomfort that aligns with the idea of being overly loud and potentially jarring to the ears. This type of laughter lacks the pleasantness or subtlety that might be found in softer or more refined expressions of amusement.

In contrast, the other choices present descriptions that do not match the given scenario. "Soft" suggests a gentle and quiet sound, which directly contradicts the concept of loudness. "Melodious" implies a pleasant and harmonious tone, evoking sweetness and musicality, which would be far removed from the harshness associated with raucous laughter. Finally, "hushed" indicates silence or quietness, again opposing the idea of loudness. Thus, raucous is the word that most accurately aligns with the intended description of laughter that is uncomfortably loud and harsh.
