Abstract

The invention discloses a noise sound quality detection device and method. The method comprises a sound sample collection module which is used for obtaining a sound signal of a to-be-detected place asa sample signal, an objective parameter calculation module which is used for calculating objective parameters of the collected sample signals, a comprehensive parameter calculation module which is used for adopting a corresponding calculation model to calculate and obtain comprehensive parameters according to application scene requirements, and an evaluation result display module which is used for carrying out evaluation according to the calculation result obtained in the comprehensive parameter evaluation model to obtain an evaluation result reflecting the subjective feeling of the human body. The noise is evaluated by using the sound quality, and the influence of underestimated low-frequency noise on a human body due to large attenuation of the A sound level in a low-frequency region isavoided.

Description

technical field [0001] The present application relates to the technical field of audio detection, in particular to a device and method for noise sound quality detection. Background technique [0002] Since the noise generated during the operation of power equipment can spread to residential areas and cause certain impacts on residents, as the public's awareness of environmental protection continues to increase, attention to the impact of noise is also increasing. The noise control of power transmission and transformation has become an urgent issue to be solved. [0003] At present, the method of evaluating the noise of transmission and substations is mainly through the measurement of A sound level, but there are certain limitations in the evaluation method of A sound level. The A sound level has a greater attenuation of the low frequency part of the noise, but the noise of the power transmission and transformation substation is mainly low frequency, so using the A sound lev...
