Introduction

Noise annoyance is people's direct perception of noise, and noise annoyance is a measure to determine the acceptability of environmental noise exposure and formulate environmental noise levels: An important basis for the standard can be determined through social acoustic surveys or laboratory listening experiments: Socio-acoustic survey on noise annoyance, my country The corresponding guiding technical document GB /Z 21233-2007 "Social Survey of Acoustic Application and Social Acoustic Survey Evaluation of Noise Trouble" has been released: Annoyance": However, in the auditory experiment of the noise annoyance laboratory, different personnel use different methods (such as sound sample playback, questionnaire design, etc:): measurement, quantification of annoyance, data processing, etc:), especially the lack of reference sound samples in the experimental sample group, and the experimental participants in the evaluation of noise annoyance (by The evaluation grade is often given according to the relative size of the annoyance of the sound samples in each experimental sample group: In the case of calibration, the annoyance evaluation results of different experimental sample groups are not comparable: Therefore, it is necessary for laboratory evaluation of noise annoyance A unified standard for pricing methods: In order to meet statistical requirements, when determining noise annoyance through social acoustic surveys or laboratory listening experiments, it is necessary to investigate a large number of respondents or Recruiting a large number of subjects requires a lot of manpower, material resources and time: Using the annoyance prediction model, the annoyance of the sound samples can be predicted: The noise annoyance prediction model can be divided into a perceptual annoyance model and a psychoacoustic annoyance model: The two have different value ranges and cannot be directly compared: Compare: The perceptual annoyance model is generally established separately for different types of noise, and is only applicable to the noise type, while the psychoacoustic annoyance model is Has a certain versatility: The psychoacoustic annoyance of noise samples can be determined directly by calculation: To determine the perceptual annoyance, it is necessary to establish a conversion model between perceptual annoyance and psychoacoustic annoyance for different types of noise: Therefore, it is necessary to The noise annoyance prediction model and its establishment method are formulated as a unified standard: Evaluation and Prediction Method of Acoustic Noise Annoyance

1 Scope

This document describes the evaluation method of noise annoyance based on auditory experiments and the prediction model of perceptual annoyance and psychoacoustic annoyance and its Conversion model building method: This document is applicable to the evaluation and prediction of outdoor environmental noise annoyance, indoor environmental noise and other noises affected by outdoor environmental noise: The evaluation and prediction of sound annoyance can refer to this document: NOTE: Certain provisions in this document may not be consistent with specific requirements or protocols for auditory experiments in other fields, and this document does not deny their value and validity:
