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，聲波產(chǎn)生的力量作用在振膜上，引起振膜振動，帶動音圈作相應(yīng)振動，音圈在磁鋼中運(yùn)動，產(chǎn)生電動勢，聲音信號轉(zhuǎn)變成電信號。</span> </p> <p> <span style="font-size:16px;">錄音室常見的錄音話筒分為動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，不錄音的時候要放到防潮柜儲存。</span> </p> <span style="font-size:16px;">動圈話筒的特點(diǎn)，是對環(huán)境適應(yīng)能力強(qiáng)。動圈話筒構(gòu)造相對簡單，經(jīng)濟(jì)耐用，武漢麥克風(fēng)話筒什么品牌好，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，一般來講，電容話筒在靈敏度和頻率響應(yīng)方面要優(yōu)于動圈話筒。這跟電容話筒需要先將聲音信號轉(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，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;">一般的入門級聲卡，話放能力有限，對于動圈話筒的支持并不好，常見的情況就是推力不夠，武漢麥克風(fēng)話筒什么品牌好，武漢麥克風(fēng)話筒什么品牌好，所以我還是建議用電容話筒錄音。</span> </p> <span style="font-size:16px;"></span> <p> <br />

style="font-size:16px;">在專業(yè)的KTV音響設(shè)備調(diào)試時，話筒音量和伴奏音量的分配占比是6：4，話筒音量占比60%，伴奏音樂音量占40%，一般來說按照這樣的占比進(jìn)行調(diào)整就可以了。</span> </p> <p> <span

style="font-size:16px;">在演唱者容易唱歌找不到拍子、唱歌走調(diào)的情況下，就可以通過加大伴奏的音量來修飾演唱者的音色，達(dá)到良好的視聽效果。</span> </p> <span style="font-size:16px;"></span>

style="font-size:16px;">有很多客戶問我演出話筒的音質(zhì)是不是一定比KTV話筒的音質(zhì)好？</span> </p> <p> <span style="font-size:16px;">答案是：不一定。</span> </p> <p> <span style="font-size:16px;">有這種想法其實是心理暗示。因為演出的話筒比較貴，KTV話筒比較便宜些。</span> </p> <p> <span style="font-size:16px;">大部分人都是覺得越貴越好。</span> </p> <p> <span style="font-size:16px;">其實不是這樣的哈。</span> </p> <p> <span style="font-size:16px;">演出話筒是高音的，適合開闊的環(huán)境用。如果在家里十幾平方米的地方用，很容易發(fā)生嘯叫的。</span> </p> <p> <span style="font-size:16px;">這是因為空間太小，聲音反射比較嚴(yán)重。音頭同時接收你說話的聲音和被墻壁反射回來的聲音。</span> </p> <p> <span style="font-size:16px;">KTV話筒是低音的，適合室內(nèi)的環(huán)境使用。一般來講，室內(nèi)比較適合。</span> </p> <p> <span style="font-size:16px;">KTV話筒用在戶外比較開闊的地方，聲音會有點(diǎn)小，不過要求不是很高的話也是適用的。</span> </p> <p> <span style="font-size:16px;">無論是KTV話筒還是演出話筒都是帶點(diǎn)效果的。</span> </p> <p> <span style="font-size:16px;">大家要記住，不同類型的無線話筒要用在不同地方才能發(fā)揮它的效果。</span> </p> <p> <span style="font-size:16px;">貴的也不一定適合你，好用就行哈。</span> </p> <span style="font-size:16px;"></span> <p> <br /> </p><p style="text-indent:25px"><span

style="font-size:16px;">消除反饋嘯叫要從產(chǎn)生反饋嘯叫的必要條件入手，只要能破壞其中一個條件，就可達(dá)到目的。</span> </p> <p> <span style="font-size:16px;">調(diào)整距離法</span> </p> <p> <span style="font-size:16px;">既避免嘯叫又能提升擴(kuò)音音量的方法之一就是將話筒盡量靠近聲源拾音，同時話筒應(yīng)使用無指向性的。在這里明確一下，指向性話筒(尤其是銳指向性話筒)遠(yuǎn)距離聲源的拾音衰減很小，調(diào)整距離對提升擴(kuò)音音量和防止嘯叫的作用不大。擴(kuò)聲系統(tǒng)是否容易嘯叫，與話筒的靈敏度沒有直接關(guān)系。只不過高靈敏度的話筒都是銳指向性的，容易產(chǎn)生嘯叫罷了。縮短發(fā)聲設(shè)備與聽眾的距離，實際上可以提升擴(kuò)音的響度?？蛇m當(dāng)?shù)臏p小系統(tǒng)的總增益。若同時輔以指向性寬的近場音箱，話筒稍微離遠(yuǎn)點(diǎn)就能避免嘯叫。</span> </p> <p> <span style="font-size:16px;">對于揚(yáng)聲器的直接反饋聲場來說，就是話筒距揚(yáng)聲器越遠(yuǎn)越好，揚(yáng)聲器距聽眾越近越好。話筒應(yīng)放在揚(yáng)聲器輻射方向的背面，如果話筒有可能被拿著四處走動，揚(yáng)聲器應(yīng)放在話筒無法靠得很近的地方。</span> </p> <p> <span style="font-size:16px;">頻率均衡法(寬帶陷波法)</span> </p> <p> <span style="font-size:16px;">由于話筒拾音和發(fā)聲設(shè)備的頻率曲線不是理想平坦的直線(特別是一些質(zhì)量比較差的放音設(shè)備)，以及廳堂聲場的聲學(xué)諧振作用，使頻率響應(yīng)起伏很大。</span> </p> <span

style="font-size:16px;">作為從電話（Telephone）傳聲筒分離出來的設(shè)備，話筒（Microphone）的發(fā)展大概100多年，百年來 “聲/電轉(zhuǎn)換” 的技術(shù)**并不多，除了《國王的演講》中的 “碳話筒” 已淘汰，后來的鋁帶話筒、動圈話筒、和電容話筒都是目前比較主流的。</span> </p> <p> <span style="font-size:16px;">鋁帶話筒 - Ribbon Microphone</span> </p> <p> <span style="font-size:16px;">它與電容話筒都是上世紀(jì)30年代興起的技術(shù)，歐洲人民偏好電容話筒，美國人民偏好鋁帶話筒，形成了一種行業(yè)習(xí)慣直到，可謂美國的 “國民話筒”。聲音特點(diǎn)是肥暖（低頻出色）、銜接平滑、瞬態(tài)較慢、高頻偏少，簡而言之是 “舒服、不刺激”，輕爵士和慢歌御用，有時也用于替代動圈話筒錄制大聲壓（例如吉他箱）或高頻太亮（例如小號）的樂器。</span> </p> <p> <span style="font-size:16px;">盡管在八九十年代逐漸被電容話筒取代，但2000年以后鋁帶技術(shù)有重大進(jìn)展，電容話筒反而停滯不前。到2015年前后，新式鋁帶話筒已能達(dá)到電容話筒的靈敏度與頻率響應(yīng)，同時依然保持了以前的音色特點(diǎn)，價格也大幅下降，成為音樂人的新選擇。</span> </p> <span
