The word "聒噪" is formed by combining the characters "聒" and "噪", where each character contributes to the meaning of noise. "聒" consists of "耳" (ear) and "舌" (tongue), implying sound that is heard and often irritating, while "噪" consists of "口" (mouth) and "喿" (associated with chirping or clamor), denoting loud or chaotic sound. Together, they create a compound word that specifically refers to loud, bothersome noise, typically from voices or similar sources.
