METHOD AND SYSTEM FOR MASKING NOISE

摘要

A method is disclosed for masking noise originating from rotary equipment in a vehicle engine. The method may include checking if engine input conditions fulfill engine input condition threshold values. If the engine input conditions fulfill the engine input conditions threshold values, the method may include outputting a first masking noise from a speaker. The first masking noise may include a first central frequency, a first predetermined bandwidth and a first amplitude, where the first central frequency and the first amplitude are determined by the input conditions. The disclosure also relates to a system for masking noise originating from rotary equipment in a vehicle engine.

1. A method for masking noise originating from rotary equipment in a vehicle engine, the method comprising:
checking if one or more engine input conditions fulfill one or more engine input condition threshold values; and if the one or more engine input conditions fulfill the one or more engine input condition threshold values, outputting a first masking noise from at least one speaker, wherein the first masking noise comprises a first central frequency, a first predetermined bandwidth and a first amplitude, and wherein the first central frequency and the first amplitude are determined by the input conditions.
