Noise sound quality evaluation method based on human-computer interaction interface

Abstract

The invention discloses a noise sound quality evaluation method based on a human-computer interaction interface. The noise sound quality evaluation method includes the steps that a noise sound pressure time domain signal is obtained, and a noise audio file is recorded; the psychoacoustic parameter loudness L, the speech articulation AI, the sharpness S and the roughness R of the noise sound pressure time domain signal are calculated; the psychoacoustic parameter loudness L, the speech articulation AI, the sharpness S and the roughness R are substituted into a noise sound quality evaluation empirical formula F=a0+a1L+a2AI+a3S+a4R to obtain a subjective evaluation prediction score F of the noise sound quality. According to the noise sound quality evaluation method based on the human-computerinteraction interface, a determination method of coefficients in the noise sound quality evaluation empirical formula is provided, after the empirical formula is established, when the noise sound quality of a plurality of products needs to be evaluated, the subjective evaluation score of the noise sound quality of each product is predicted through the noise sound quality evaluation method and theempirical formula, and ranking is conducted according to the predicted subjective evaluation score, so that the noise sound quality of the products can be obtained.

Description

technical field [0001] The present invention relates to the technical field of product noise detection, in particular to a noise sound quality evaluation method and system based on a human-computer interaction interface. Background technique [0002] The noise of mechanical products, such as household appliances, vehicles, aircraft, etc., not only affects the user experience, but also has a significant impact on the physical and mental health of the human body. In engineering applications, acoustic microphones are often used to measure the sound pressure level of noise, and this index is used to evaluate the annoyance of noise. However, the sound pressure level cannot accurately reflect the human ear's perception of sound. For example, the sound emitted by the range hood during operation usually makes users feel uncomfortable, and the sound pressure level of its noise is between 50dB(A) and 65dB(A). However, the sound pressure level of the speakers in the home theater can ...
