Sum of all measures, which the system designer must take for a given pump (motor) to produce a quiet system (see noise creation in hydraulic systems). Specifically, this means:
- measures, which can reduce the transmission of structure-borne noise. This relates primarily to the oscillation-insulated assembly of the pump to prevent the bodies which can oscillate greatly, such as oil drums and the assembly wall, amongst others, from resonating.
- Measures to reduce the transmission of pressure and flow rate fluctuations in the fluid. This includes the use of hydraulic accumulators or expandable hoses for oscillation damping and silencers.
- Measures to prevent the transmission of sound in air. This is done by encapsulating the machine or the hydraulic power pack.
