‘宏亮’ (hóng liàng) is an adjective meaning 'resonant' or 'sonorous'—describing a voice or sound that is rich, powerful, clear, and carries well. The character 宏 (hóng) means 'grand', 'vast', or 'magnificent', suggesting amplitude and breadth; 亮 (liàng) means 'bright' or 'clear', evoking clarity and brilliance. Together, they form a compound that emphasizes both volume and purity of tone—not just loudness, but full-bodied, ringing quality.

This word is commonly used to describe human voices (e.g., a speaker’s or singer’s voice), musical instruments (like a trumpet or bell), or natural sounds (such as thunder). It carries a positive, often admiring connotation and appears frequently in formal speech, literature, broadcasting, and performance contexts. It is not used for mechanical or electronic sounds (e.g., alarms or speakers) unless stylistically elevated or metaphorical.
