There are some studies in the literature in order to make the interpretation of human tissues having different characteristics. Some of these studies focused on the evaluation of human face tissues. Vibration signals generated from vocal cords have been used in these studies about human face tissues. However, any study using the vibration signals recorded by applying the external vibration source having fixed frequency value is not available in the literature. In this study, it is aimed to investigate the frequency characteristics of the vibration signals recorded from the human face. These signals obtained from nine different regions on the faces of subjects are analysed using frequency characteristics. In the analysis stage, median and maximum frequency values are calculated and evaluated. So, the softness and hardness interpretation about these regions on the face can be made and the frequency ranges of these regions can be determined. As a result, it is observed that low-frequency signals are dominant in hard regions and high-frequency signals are dominant in soft regions.

使用中频和最大频率评估人脸的振动测量

为了对具有不同特征的人体组织进行解释，文献中进行了一些研究。这些研究中有一些集中在评估人脸组织。从声带产生的振动信号已用于有关人脸组织的这些研究中。但是，在文献中没有进行使用通过施加具有固定频率值的外部振动源而记录的振动信号的研究。在这项研究中，旨在研究从人脸记录的振动信号的频率特性。使用频率特性分析从对象面部的九个不同区域获得的这些信号。在分析阶段，将计算和评估中值和最大频率值。所以，可以对面部这些区域进行柔软度和硬度的解释，并可以确定这些区域的频率范围。结果，观察到在硬区域中低频信号占主导，而在软区域中高频信号占主导。
