【閱兵'好聲音'煉成記】
It is learned that 315 engineers are responsible for the sound effect of the grand parade to mark the 70th anniversary of victory in the People's War of Resistance against Japanese Aggression. They placed more than 300 microphones, 62 sound base stations, 38 sound consoles and 140 mobile loudspeaker boxes in Tian'anmen Square and districts along the Chang'an Avenue. The various kinds of sound on the site of parade are more complicated than ever, making sound collecting a hard job.
據了解，此次抗戰勝利70周年閱兵，共有315名工程師承擔閱兵聲音保障任務。他們在天安門廣場以及長安街區域布設了300多支話筒、62個聲音基站、38個調音臺及140只流動音箱。此次閱兵現場聲音種類的繁雜是前所未有的，使得聲音收集工作變得非常復雜。
[聲音收集無死角]
In order to convey neat and uniform sound of footsteps of march-past, apart from installing fixed sound-collecting microphones, technicians have to follow the formation carrying a microphone stick to collect their sounds. The amplifying systems on Tian'anmen Square in this parade cover vast areas from Jianguomen to Xidan, to ensure unified sound effect in every corner of the square.
為了傳遞出整齊劃一的分列式腳步聲，除了布設固定的拾聲話筒外，還有技術人員舉著話筒桿，朝著腳步行進方向跟隨收聲。本次閱兵，天安門廣場的擴聲系統覆蓋了從建國門到西單的廣闊區域，保證在廣場上任何角落都能聽見一致的效果。
[口令員精準發聲]
Order-givers in the phalanxes are responsible to give loud orders on the Tian'anmen Square for soldiers to hear. Besides, they should notice not to give orders when guns fire salute. There are standards for how long one order lasts, the strong beat and off beat in the order, as well as the rhythms.
方隊中的口令員負責在天安門廣場上喊出響亮的口令，讓官兵們都能聽見。而且口令要與禮炮響那一刻的時間點錯開。喊多長、哪個地方是強音、哪個地方是弱音，用什么節拍，都有規范。
[腳踏聲要響亮]
In order to march with such momentum, soldiers trained wearing heavy sandbags on their legs. The riding boots that soldiers wear are very heavy in itself, and the hardness of these boots' heels was increased to 85 (hardness of normal heels is between 65 and 75), which makes the stomping sound louder.
為了走出氣勢，隊員在訓練時通過加重腿部沙袋重量，來加強腿部功夫訓練。馬靴本來就很沉，普通的鞋跟硬度為65到75之間，此次閱兵鞋跟硬度加到85，可以讓腳踏聲更響。
