    我校素養課學生參觀同濟大學環境科學與工程學院聲學所

    2017年4月14日下午,我校選修“生活中的環境學”素養課的30名學生乘車前往同濟大學環境科學與工程學院聲學館參觀。

    同濟大學環境科學與工程學院院黨委副書記錢昕、學工辦老師馮天磊(我校2009屆校友)等前來迎接,帶領同學們分批參觀各實驗室。錢書記介紹了環境科學與工程學院的基本情況,學生們隨后參觀聲學館。聲學研究所三名研究生為同學們全程解說。

    同學們認真聆聽講解

    同學們先后參觀了全消聲室、混響室和輪胎噪聲實驗室。全消聲室近1200立方米,是遠東最大的全消聲室。由于室內做了全消聲處理,室內人員必須大聲講話才可以讓他人聽見。同學們紛紛嘗試,高聲喊叫依舊徒勞無功。

    同學們在全消聲室內進行活動體驗

    混響室內聲波反復疊加,回聲不斷。同學們低聲講話也會產生較大的回響,聲音不絕于耳。輪胎噪聲實驗室主要用來研究車輪運轉時的噪聲情況。

    擔任引導和解說的研究生們當場為同學們進行了一次實驗演示:輪胎飛速轉動,與模擬路面發生摩擦,六個拾音器將聲音數據傳輸到分析電腦,研究人員在電腦上即可根據數據分析輪胎噪聲特點。實驗進行時,同學們緊盯數據曲線,目光隨著曲線的變動而變動,儼然自己就是研究人員。

    同學們認真觀測數據變化

    整個參觀活動持續了一個多小時,盡管時間短,但同學們收獲頗豐。同學們一路走、一路看、一路記,將聽到的、看到的記下來,還不時向研究人員提問。

    該參觀體驗活動是存志學校學生素養培育課程校外實踐環節之一。學生們在校內素養課程上接觸到、學習到的相關專業知識,從書本上的平面知識轉化為身邊日常可見的現象,學生們通過觀察、聆聽講解、體驗實踐進一步延伸和消化這些知識,在潛移默化中提升人文科技素養。
