What does 声音 mean?
声音 (shēngyīn) means 'sound' or 'voice' — any audible noise, including a person's voice, a musical sound, traffic noise, or animal calls. Literally 声 'sound' + 音 'tone' — a redundant compound where both characters carry the meaning. Differences from English: English splits 'voice' (from a person) and 'sound' (everything else), but 声音 covers both. To specify, you can say 他的声音 ('his voice') or 鸟的声音 ('the sound of birds').
For volume, use 大 / 小: 声音大 ('loud'), 声音小 ('quiet / soft'), 把声音开大一点 ('turn the volume up'). To 'make a sound' is 发出声音; to 'lower your voice' is 小声一点. Related compounds: 大声 (loudly)

Memory hook: 声 + 音 both mean 'sound' — doubled up for emphasis: sound / voice.

Common phrases with 声音
Synonyms
嗓音 specifically refers to the quality of a person's voice (deep, hoarse, sweet). 声音 is broader — any sound, including a voice. A singer's 嗓音 is her vocal quality; 她的声音 is more general 'her voice.'
Bare 音 is mostly used in compounds (音乐 music, 录音 recording, 拼音 pinyin) and rarely stands alone for 'sound.' Use 声音 in normal speech.
