摘 要：
本研究旨在验证羽毛球拍击球时的声音特点，探究击球力度、球拍线磅数与分贝数、声音频率、泛音的关系。研究方法是通过手机采集不同条件下的声音样本，并使用adobe audition分析。最终得出以下结论：1. 击球力度越大、球拍线磅数越高，分贝数越大；2. 球拍磅数增加会使声音频率升高，测试球拍频率在950Hz-1020Hz范围，高磅数球拍采样频率浮动更稳定；3. 同一球拍同一位置的击球力量对频率无明显影响；4. 击球基音与泛音无倍数关系，推测这是源于球拍多部件结构及击球点偏差导致的复杂共振；5. 噪音环境中使用手机采集声音易产生偏差，本次测试环境的噪音分布在0-16000Hz且难以过滤。本研究为羽毛球运动的客观分析提供了音频分析新思路。

Abstract:
This study aimed to verify the acoustic characteristics of badminton rackets upon impact and explore the relationships between stroke force, racket string tension and sound decibel level, frequency as well as overtones. Sound samples under different conditions were collected via mobile phones and analyzed with Adobe Audition. The main conclusions are as follows: 1. Higher stroke force and racket string tension both lead to a higher decibel level; 2. An increase in string tension elevates the sound frequency, with the tested rackets showing a frequency range of 950Hz-1020Hz, and the sampling frequency of rackets with high string tension presenting more stable fluctuations; 3. For the same racket and impact point, stroke force has no significant effect on sound frequency; 4. There is no multiple relationship between the fundamental frequency and overtones of the impact sound. It is inferred that this results from complex resonance caused by the multi-component structure of the racket and deviations in the impact point; 5. Sound collection via mobile phones in a noisy environment is prone to errors, and the noise in the test environment of this study was distributed in the range of 0-16000Hz and difficult to filter out. This study provides a new audio analysis approach for the objective analysis of badminton sports.
