Substantially — fibrous thermal materials are decent acoustic absorbers, and mass-loaded jacketing adds transmission loss. Mineral-wool systems with metal cladding routinely deliver 5–15 dB(A) insertion loss on pipework; engineered acoustic-thermal removable covers reach 10–25 dB on valves (where throttling noise concentrates). If a line has both a heat and a noise problem, one engineered cover usually beats two separate fixes.
