Etymology
'sound-insulating' originates from modern English as a compound of the noun 'sound' and the present-participle form of the verb 'insulate'. 'sound' in this sense refers to audible vibration or 'noise', and 'insulate' derives from Latin 'insula' meaning 'island'.
'insulate' entered English via Late Latin/Medieval Latin (e.g. 'insulatus') and Romance-language forms and came to mean 'to make into an island/ isolate'; the compound adjective 'sound-insulating' is a modern English formation combining 'sound' + 'insulating'.
Initially, the root 'insula' referred to an 'island' (and 'insulate' originally meant 'to make like an island' or 'to isolate'); over time 'insulate' expanded to mean preventing passage of heat, electricity, or sound, and thus 'sound-insulating' now specifically denotes preventing transmission of sound.
