style="font-size:16px;">了解基本的指向性使用原則有助于在每一次錄音中都得到較好的結(jié)果，指向性決定一支話筒在不同角度的靈敏度。也就是說(shuō)，決定了在不同方向，有多少信號(hào)被拾取。</span> </p> <p> <span

style="font-size:16px;">首要的，你要能正確地閱讀指向性圖表。它包括了影響你錄音的所有必要信息。</span> </p> <p> <span style="font-size:16px;">試著想象話筒在一個(gè)360度寬敞的場(chǎng)地里，0度是話筒的正面，這個(gè)角度的話筒具有較大的靈敏度。指向性的圓圈的涵蓋了一些小圈，每一個(gè)圈衰減5dB。</span> </p> <p> <span style="font-size:16px;">分貝是(dB)是對(duì)比兩個(gè)數(shù)值的的對(duì)立單位。如果一支具有心型指向參數(shù)的話筒具有25dB，那么，敏感度較高的部分(0°)和敏感度較低的部分(180°)呈對(duì)比。</span> </p> <p> <span style="font-size:16px;">對(duì)聲壓，當(dāng)前和電壓+6 dB信號(hào)放大了兩倍，+20 dB會(huì)導(dǎo)致10倍信號(hào)。典型的心型指向的離軸反應(yīng)是-20 dB。</span> </p> <span style="font-size:16px;"></span> <p> <br /> </p><p> <span style="font-size:16px;">手持話筒</span> </p> <p> <span style="font-size:16px;">可以利用話筒架子來(lái)固定話筒，值得注意的是麥克風(fēng)不要放在嘴與地面平行的直線上，應(yīng)低于嘴唇，放在嘴的下部且與嘴成45°角，這樣才能靈活運(yùn)用，否則會(huì)出現(xiàn)抬頭時(shí)被話簡(jiǎn)攔住臉部的情況。</span> </p> <p> <span style="font-size:16px;">調(diào)好麥克風(fēng)的位置后，不要用手去敲，看有沒(méi)有聲音，也不要用嘴吹，這些動(dòng)作很不雅觀?？蓹z查麥克風(fēng)的開(kāi)關(guān)是否開(kāi)了，麥克風(fēng)的開(kāi)關(guān)向上是開(kāi)，向下是關(guān)，這是國(guó)際統(tǒng)一的。</span> </p> <p> <span style="font-size:16px;">有時(shí)可能沒(méi)有話筒架，那么麥克風(fēng)只能拿在手里了，握麥克風(fēng)時(shí)不要太緊，握得太緊手容易頗動(dòng)，會(huì)使聽(tīng)眾以為你很緊張。可以握成拳狀，也可握成抓狀，但一般采用前者。不要隨意換手，如果要換，一定要配合好動(dòng)作進(jìn)行。</span> </p>

style="font-size:16px;">演講者根據(jù)場(chǎng)地的大小和麥克風(fēng)的性能以及聽(tīng)眾情緒的靜噪情況，可以靈活調(diào)整嘴與麥克風(fēng)的距離。場(chǎng)地大，尤其是在室外，或者麥克風(fēng)性能差、聽(tīng)眾浮躁不安、人群中有聲音時(shí)，可以近點(diǎn)，否則應(yīng)遠(yuǎn)點(diǎn)。</span>

alt="武漢bbs話筒維修,話筒" src="https://tyunfile.71360.com/UploadFile/jzwhywxtjc/637378590976835938/2976964.png"></div><p> <span style="font-size:16px;">如何正確調(diào)試話筒錄出好聲音？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">話筒話筒也叫傳聲器，工作原理是當(dāng)傳聲器接受聲波時(shí)，聲波產(chǎn)生的力量作用在振膜上，引起振膜振動(dòng)，帶動(dòng)音圈作相應(yīng)振動(dòng)，音圈在磁鋼中運(yùn)動(dòng)，產(chǎn)生電動(dòng)勢(shì)，聲音信號(hào)轉(zhuǎn)變成電信號(hào)。</span> </p> <p> <span style="font-size:16px;">錄音室常見(jiàn)的錄音話筒分為動(dòng)圈話筒和電容話筒兩種。</span> </p> <p> <span style="font-size:16px;">電容話筒的特點(diǎn)是非常靈敏，頻率響應(yīng)比較寬廣，能夠捕捉到更多聲音細(xì)節(jié)，在錄音棚中使用率較高，對(duì)錄音環(huán)境的要求也比較高。電容話筒非常嬌貴，怕摔怕受潮，不錄音的時(shí)候要放到防潮柜儲(chǔ)存。</span> </p> <span style="font-size:16px;">動(dòng)圈話筒的特點(diǎn)，是對(duì)環(huán)境適應(yīng)能力強(qiáng)。動(dòng)圈話筒構(gòu)造相對(duì)簡(jiǎn)單，經(jīng)濟(jì)耐用，能承受極高的聲壓，且?guī)缀醪皇軜O端溫度或濕度的影響。</span> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">從聲學(xué)性能比較，一般來(lái)講，電容話筒在靈敏度和頻率響應(yīng)方面要優(yōu)于動(dòng)圈話筒。這跟電容話筒需要先將聲音信號(hào)轉(zhuǎn)換成電流的工作原理有關(guān)。通常電容話筒的振膜都非常薄，很容易受到聲壓影響而發(fā)生震動(dòng)，從而引起振膜與振膜艙后背板之間電壓的相應(yīng)改變。</span> </p> <p> <span style="font-size:16px;">一般的入門級(jí)聲卡，話放能力有限，對(duì)于動(dòng)圈話筒的支持并不好，常見(jiàn)的情況就是推力不夠，所以我還是建議用電容話筒錄音。</span> </p> <span style="font-size:16px;"></span> <p> <br />
