摘要
随着用户对家电产品听觉舒适性越来越关注,家电行业对声品质评价的研究及应用也越来越广泛。以电冰箱产品的噪声为研究对象,采集多台样品的声样本,并对其进行声品质主观评价;在数据处理后,结合客观参数计算结果,对电冰箱不同工况的噪声建立了声品质模型。研究结果表明,影响电冰箱声品质水平的主要客观因素是响度、音调度、粗糙度、尖锐度。
As users pay more attention to the acoustic comfort of household appliances,the research and application of sound quality evaluation in the household appliances industry are becoming more and more extensive.Taking the noise of refrigerator products as the research object,collecting the sound samples of several sets of samples,and carrying out the subjective evaluation of the sound quality.After the data processing,combined with the objective evaluation results,the sound quality model of the refrigerator noise under different working conditions was established.The results show that the main objective factors affecting the sound quality of refrigerators are loudness,tonality,roughness and sharpness.
