中文摘要 | 本文針對不同高爾夫球桿進行擊球聲音測試,主要探討其音頻特性。以麥克風為感測器量測得擊球聲音線性頻譜資訊,由樂音角度探討其差異性,也將線性頻譜資訊轉換成三分之一八音頻帶,並藉由室內噪音評估標準探討不同球桿擊球聲音差異,以期建立高爾夫球桿擊球聲音有一量化指標。本文除了對高爾夫球擊球聲音品質差異性有初步瞭解,亦探討不同球桿擊球之聲音差異,希望發展為高爾夫球桿之品質指標之一,作為球桿設計製造參考。 |
英文摘要 | This work performs swing tests for different golf clubs to characterize the sound properties. First, the sound quality is defined, and made a description of its difference and expression. Swing tests for different golf clubs are then carried out to determine the linear spectrum data by the microphone. The impact sound characteristics are discussed from the point of view in musical tones. Furthermore, the linear spectrum data is transferred to 1/3 octave band and the different sound quality is characterized by room noise rating index. This work establishes the general idea for sound quality of swing test for different golf clubs, and characterizes the difference of swing test for different golf clubs. The selection of proper quality index for golf clubs is desired and will be beneficial to the golf club design. |
