                                                                                                                                              醫用隔音設備

                                                                                                                                                  鋪地資料類撞擊聲及隔聲功能檢測,靜音房以供工人觀察操控機器工作或是休憩用,按實際需要也要設置門、窗和通風管道,其他一些生產會有檢驗要求的產品制造車間規劃的隔聲檢驗裝置,在隔聲間內進行吸聲處理,使其成為一個小型的無聲室,在里面可檢驗一些小型的產品,如精密儀器、電機、音響、變壓器等,靜音房是用于檢測設備的工作間,可為活動靜音房,靜音房選用四面及頂面吸聲,底層隔聲的方式使室內到達低噪聲環境,其在隔音房內本底噪聲值小于35-40dB(A)。

                                                                                                                                                  隔音房除設置吸聲系統外,其間空氣聲隔聲實驗室測試洞口最大尺度為4.22.8m,混響室容積為268m?,可滿意各國標準和各類尺度的修建資料聲學檢測要求,一起裝備了B&K聲學最新的聲學測試系統,確保了測試數據的準確性和可靠性。
