Sense: adjective/1

Quiet is the broadest and most common word, covering anything that makes little noise — a quiet car, a quiet voice, or a quiet street. Silent is stronger, meaning completely without sound or speech — a silent room, a silent film, or someone who stays silent. Noiseless overlaps with silent but is less common and often used in technical or descriptive writing to emphasise that a mechanism, machine, or place operates without sound (e.g. a noiseless fan, noiseless footsteps). Soundless is the rarest, appearing mostly in literary prose to suggest a near-absolute absence of sound in a setting. While a quiet room may still hold faint background noise, a noiseless or silent room would have none. In everyday conversation, quiet is the natural choice; the other three sound more deliberate or formal.

Etymology

LatinOld FrenchEnglish

Formed in English by joining the noun 'noise' (meaning unwanted sound, from Latin 'nausea' — sickness or discomfort) with the suffix '-less' (meaning 'without'). The compound first appeared in the 16th century and has been used ever since to describe things that produce no audible sound.
