擴音器,麥克風,話筒將聲波轉變成電流的工具,通常接至擴音器,錄音機或廣播發射機上Finally, the results are compared with periodic and random chains. then we studied acoustic wave propagation in 1d quasiperiodic and aperiodic systems by means of he transfer matrix. transmission rate, reflection rate, energy flow, logarithmic energy flow, energy density and lyapunov exponent are computed numerically, and compared with periodic and random system
其次研究了聲波在幾種一維準周期和非周期系統中的傳播,通過轉移矩陣的方法,數值地得到了系統的傳播系數t _ n 、反射系數r _ n 、能流密度j _ n ,能量密度e _ n和lyapunov指數,給出了以上各量與傳播長度n以及頻率之間的關系,同時發現能流及能量密度都具有分形結構,並與周期和隨機系統的結果作了比較。分享友人
