METHOD AND SYSTEM FOR MASKING NOISE

The invention relates to a method for masking noise originating from rotary equipment in a vehicle engine. The method comprises: - checking if one or more engine input conditions fulfil engine input condition threshold values, wherein, if said one or more engine input conditions fulfil said engine input conditions threshold values, - outputting a first masking noise from at least one speaker (6), wherein the first masking noise comprises a first central frequency, a first predetermined bandwidth and a first amplitude, wherein the first central frequency and the first amplitude is determined by said input conditions. The invention also relates to a system (1) for masking noise originating from rotary equipment in a vehicle engine.
