Method and device for measuring noise perception intensity and electronic equipment

The invention provides a method and device for measuring the noise perception intensity and electronic equipment, and relates to the technical field of signal processing. The method includes the stepsthat original brain wave signals are obtained, wherein the original brain wave signals are brain wave signals monitored at the time of a subject listening to a preset audio frequency, the preset audio frequency is multiple segments of audio frequencies formed by adding target noise intensity noise to an original audio frequency, and target noise intensity is any one kind of preset noise intensity; and the noise perception intensity of the subject on the original audio frequency is determined based on the original brain wave signals. According to the method, the noise perception intensity of the subject on the original audio frequency is determined by analyzing the primary cognitive neuroelectric response (the original brain wave signals) of the subject on the preset audio frequency, and aphysiological standard fo
