The horn matters, but so do frequency, sound pressure, mounting, compressed air, sequence, controls, noise, access, commissioning and proof. A well-specified system should be judged by plant outcomes: fewer manual interventions, longer intervals between offline cleaning, more stable pressure drop, cleaner surfaces, safer work and better availability.",[54,390,391],{},"That is why \"acoustic cleaning system\" is the right phrase for the problem.
