The sound quality of a range hood is one of the most common complaints from consumers. As a supplement to sound power target, sound quality evaluation and prediction describes subjective feeling more suitably. It is proved that conventional sound quality model is able to predict sound quality accurately. However, the conventional model does not offer practical strategies for the design of a range hood. In this paper, specific psychoacoustic metrics including Area of Derivative of Specific Loudness (ADSL) and Gravity of Specific Loudness (GSL) are proposed. The multiple linear regression model based on ADSL and GSL has an adjustable R square of 0.92. The target determined by the model is proven more preferred than original by subjective assessment. An innovative method of sound reinforcement is proposed in the present work, and is applied on a range hood based on the strategies. The sound pressure levels in the target frequency region are reinforced, which makes the sound loudness curve more close to the target curve. The work in this paper offers an example of application of sound quality model on the design of a range hood.

吸油烟机的音质是消费者最普遍的抱怨之一。作为声功率目标的补充，声音质量评估和预测可以更适当地描述主观感觉。实践证明，传统的声音质量模型能够准确地预测声音质量。但是，传统模型没有为抽油烟机的设计提供实用的策略。本文提出了包括特定响度的导数面积（ADSL）和特定响度的重力（GSL）在内的特定心理声学指标。基于ADSL和GSL的多元线性回归模型的可调R平方为0.92。主观评估证明，模型确定的目标比原始目标更可取。本工作中提出了一种创新的扩声方法，并根据策略应用于抽油烟机。目标频率区域中的声压级得到增强，这使响度曲线更接近目标曲线。本文的工作提供了在吸油烟机设计中应用声音质量模型的示例。
