style="font-size:16px;">專業(yè)話筒如何更好為人聲拾音</span> </p> <p> <br /> </p> <p> <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?？s短發(fā)聲設(shè)備與聽眾的距離，實(shí)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，武漢無線手持話筒維修，武漢無線手持話筒維修，使頻率響應(yīng)起伏很大，武漢無線手持話筒維修。</span> </p> <span

style="font-size:16px;">1.保持適當(dāng)距離10至15公分（收音好的麥克風(fēng)離一拳寬；較差的離三指寬）</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">嘴部和麥克風(fēng)保持適當(dāng)?shù)氖潜匾?，如果距離靠嘴太近會導(dǎo)致聲音太大，遇到換氣氣音時會不斷的爆音；還有聲音會被迫壓低、變小而讓歌聲的抑揚(yáng)頓挫大打折扣。所以如果保持適當(dāng)距離的話，便可以讓歌聲有的發(fā)揮。</span> </p> <p> <span style="font-size:16px;">2.手握麥克風(fēng)上端或中間部分</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">一般而言，手持式無線麥克風(fēng)訊息收發(fā)的位置是在下端，因此若手持上端，可以讓麥克風(fēng)傳訊質(zhì)量更穩(wěn)定。注意不能摀住麥克風(fēng)頭，不但聲音會悶住，而且容易產(chǎn)生回授噪音。</span> </p> <p> <span style="font-size:16px;">3.盡量保持正對嘴部</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">比較老式的麥克風(fēng)，收音位置位于麥克風(fēng)頂端，所以在對著麥克風(fēng)說話時，盡量把麥克風(fēng)抬高一些，讓聲音從麥克風(fēng)的頂頭「灌」下去，這可以讓麥克風(fēng)的收音質(zhì)量較好。</span> </p> <p> <span style="font-size:16px;">4.不要握在麥克風(fēng)的頂頭上</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">以手掌抓著麥克風(fēng)頭會破壞麥克風(fēng)音質(zhì)的不良姿態(tài)，即使是名貴的麥克風(fēng)也一樣，原因是掌握網(wǎng)頂頭等于隔絕音頭改變氣室的諧振頻率，導(dǎo)致麥克風(fēng)的正面頻率響應(yīng)及指向性劣化，而且因手掌的聚音效應(yīng)會造成某一段頻率的諧振而增強(qiáng)產(chǎn)生回授聲。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;"></span> </p><p> <span style="font-size:16px;">舞臺唱歌如何正確的使用話筒 </span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">我們在前面曾提到過“通俗歌曲的演唱藝術(shù)在很大的程度上就是使用話筒的藝術(shù)”，也就是說，通俗歌手們都是利用和依靠話筒來表現(xiàn)的?，F(xiàn)代的音響設(shè)備、擴(kuò)播技術(shù)以及高質(zhì)量、性能的話筒，都是今非昔比的，運(yùn)用得當(dāng)?shù)脑捦驳耐κ蔷薮蟮模⒛茉谙喈?dāng)?shù)某潭壬厦阑曇?、改變聲音。所以歌手能否正確利用話筒，對演唱效果起著舉足輕重的作用。</span> </p> <p> <span style="font-size:16px;">首先，應(yīng)該確定嘴與話筒的距離，這是第一步?？陔x話筒太遠(yuǎn)、太近都不行。那么應(yīng)該離多遠(yuǎn)呢？這里沒有一個固定的答案，因?yàn)椴煌脑捦裁舾卸炔煌?；不同的演員音量也不同，加上劇場、擴(kuò)大器等不定因素，這就使得我們的演員們在演出之前能夠試一試話筒。試的時候要用中等音量（因?yàn)樵谘莩獣r，總是以中等音量為主的），試好后，就要記住距離。一般用自己的拳頭去量，有時是一拳之隔，有時是一拳半之隔。</span> </p> <p> <span style="font-size:16px;">這一距離確定之后，在演唱時還要有些調(diào)整。這是因?yàn)樵诓煌囊魠^(qū)，不同的力度條件下，人的音量有著很大的差別，較弱的低音與較強(qiáng)的高音可相差幾十倍。</span> </p> <p> <br />

style="font-size:16px;">1.指向性(Unidirction)</span> </p> <p> <span style="font-size:16px;">如果麥克風(fēng)只能接收某個方向的聲音就叫做指向性麥克風(fēng)。通常麥克風(fēng)正面的靈敏度，背后的靈敏度幾乎為零。這種定向麥克風(fēng)在舞臺上尤其重要，因?yàn)樗唤邮涨胺降穆曇?，從旁邊或后方來的聲音都會被排斥掉，如此可以避免很多不必要的雜音。使用時就必須小心麥克風(fēng)的方向，方向不對，收到的聲音就不對。有些麥克風(fēng)可以調(diào)整它的定向方式，使用時可以依需要調(diào)整。</span> </p> <p> <span style="font-size:16px;">2.無指向性(Omnidirection)</span> </p> <p> <span style="font-size:16px;">就是一個麥克風(fēng)可以接收各個方向傳來的聲音，而整套鼓組各粒鼓之收音，希望各別收到干凈單純之音源，無指向性麥克風(fēng)可能不是一個好選擇。</span> </p> <p> <span style="font-size:16px;">3.麥克風(fēng)的指向性也會因兩支麥克風(fēng)的接近互相干擾而讓指向特性劣化，其劣化程度隨兩支麥克風(fēng)的距離遠(yuǎn)近成正比，所以使用者應(yīng)該避免一手同時拿兩支或兩支以上麥克風(fēng)使用，避免造成音量、頻率響應(yīng)及指向性劣化。非得要同時使用多支麥克風(fēng)，則必須把麥克風(fēng)的距離至少各拉開30公分以上。</span>
