In this study, a perceived sound to the auditory system is predicted as a method to design the Gaudi bell. As the first step for design, the numerical simulation to predict a structural vibration response is conducted as the result of compared with the actual measurement, and the applicability of FEA based approach is confirmed.Next, the method to control the input function is investigated to change the vibration response with fixed structure. The method to design the hammer with an intended waveform is considered, and the pulse excitation by a shaker is applied to obtain the vibration response by an arbitrary shaped waveform. The acceleration and sound pressure are the physical quantity which is not perfectly matched with the characteristics of auditory perception. Therefore, the pitch analysis is applied to predict the actually perceived component, and the radiated sound from the designed Gaudi bell is verified.

在这项研究中，感知声音的听觉系统预测的方法来设计高迪钟。 作为设计的第一步，对结构振动响应进行了数值模拟预测，并与实测结果进行了比较，验证了有限元分析方法的适用性。其次，研究了在结构固定的情况下，控制输入函数以改变结构振动响应的方法。考虑了按预定波形设计锤头的方法，并采用振动台脉冲激励，以获得任意波形的振动响应。加速度和声压是与听觉感知特性不完全匹配的物理量。因此，音高分析被应用于预测实际感知分量，并验证了所设计的高迪钟的辐射声。
