Abstract The main goal of present work is to create a comparative evaluation methodology based on the correlation between the objective parameters of traditional acoustics and the psychoacoustic subjective parameters investigated with listening tests. This led to the definition of a quality index for kitchen hoods calculated from measurable objective parameters to provide guidance on the ultimate sound perception of the consumers. The acquisition of data was carried out in a standardized laboratory and in a typical environment representative of a kitchen, in order to study the acoustic behavior of the hood installed and operating in real conditions. For this reason, suitable listening tests have been conducted on a selected group of subjects representing a sample of potential clients of the selected kitchen hood models, with the aim of correlating human sensations and measured objective parameters. Finally, a sound quality index (SQ Index) was calculated for each of the hood models in order to highlight the best performing sample from the point of view of the pleasantness of the sound emitted in the kitchen environment.

厨房油烟机的音质评价

摘要 当前工作的主要目标是创建一种基于传统声学客观参数与通过听力测试调查的心理声学主观参数之间的相关性的比较评估方法。这导致了根据可测量的客观参数计算出的厨房油烟机质量指数的定义，为消费者的最终声音感知提供指导。数据采集​​是在标准化实验室和典型的厨房环境中进行的，目的是研究在真实条件下安装和运行的抽油烟机的声学行为。出于这个原因，我们对一组选定的受试者进行了适当的听力测试，这些受试者代表了选定厨房抽油烟机型号的潜在客户样本，目的是将人类感觉与测量的客观参数相关联。最后，为每个抽油烟机型号计算了一个声音质量指数（SQ 指数），以便从厨房环境中发出的声音的愉悦度角度突出表现最佳的样品。
