style="font-size:16px;">1.試聲時(shí)忌拍打話筒及向話筒吹氣</span> </p> <p> <span style="font-size:16px;">由于話筒的拾音部分較精密，且部件很嬌貴，拍打話筒或向咪頭吹氣極易造成損壞或部件移位，終影響音質(zhì)。</span> </p> <p> <span style="font-size:16px;">2.忌話筒離開(kāi)音源過(guò)遠(yuǎn)過(guò)近</span> </p> <p> <span style="font-size:16px;">話筒拾音時(shí)距離為10公分左右。有的“領(lǐng)導(dǎo)”講話離話筒很遠(yuǎn)，有的歌手貼著話筒，過(guò)遠(yuǎn)造成拾音聲音過(guò)小，這時(shí)如把音量推子往上推極易引起嘯叫;過(guò)近則把講話時(shí)的氣流聲也拾入，發(fā)出“噗噗”的干擾聲。</span> </p> <p> <span style="font-size:16px;">3.忌拉話筒的引線</span> </p> <p> <span style="font-size:16px;">遞交話筒時(shí)忌拉住話筒的引線。由于話筒具有一定的重量，經(jīng)常拉住引線，就極易造成引線折斷，插頭接觸不好，造成拾音故障。</span> </p> <p> <span style="font-size:16px;">4.忌使用好后不關(guān)閉話筒電源</span> </p> <p> <span style="font-size:16px;">在開(kāi)會(huì)講話時(shí)或演唱完畢后，應(yīng)及時(shí)關(guān)掉話筒開(kāi)關(guān)，這時(shí)候如音控師也未及時(shí)關(guān)閉調(diào)音臺(tái)音量推子：一方面把其他雜音也拾進(jìn)去，另一方面也把你一些不必要的講話聲播放出來(lái)。布什總統(tǒng)就有一次這樣的經(jīng)歷，造成尷尬。</span>

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;">通過(guò)選擇正確的模式，您可以避免不需要的聲源流入信號(hào)，調(diào)整干聲和室內(nèi)聲音之間的混音，或改變頻率響應(yīng)，并影響鄰近效果。</span> </p> <p> <span style="font-size:16px;">如何讀取指向圖</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 /> 無(wú)線會(huì)議話筒，武漢音王系統(tǒng)集成有限公司，專業(yè)為您服務(wù)！</p><div

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(gè)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(tái)上尤其重要，因?yàn)樗唤邮涨胺降穆曇簦瑥呐赃吇蚝蠓絹?lái)的聲音都會(huì)被排斥掉，如此可以避免很多不必要的雜音。使用時(shí)就必須小心麥克風(fēng)的方向，方向不對(duì)，收到的聲音就不對(duì)。有些麥克風(fēng)可以調(diào)整它的定向方式，使用時(shí)可以依需要調(diào)整。</span> </p> <p> <span style="font-size:16px;">2.無(wú)指向性(Omnidirection)</span> </p> <p> <span style="font-size:16px;">就是一個(gè)麥克風(fēng)可以接收各個(gè)方向傳來(lái)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(wú)指向性麥克風(fēng)可能不是一個(gè)好選擇。</span> </p> <p> <span style="font-size:16px;">3.麥克風(fēng)的指向性也會(huì)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(shí)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(shí)使用多支麥克風(fēng)，則必須把麥克風(fēng)的距離至少各拉開(kāi)30公分以上。</span>

style="font-size:16px;">比如，麥克風(fēng)的手持姿勢(shì)。</span> </p> <p> <span style="font-size:16px;">在流行唱法中，麥克風(fēng)的使用是除了歌手演唱能力本身以外關(guān)鍵的一項(xiàng)技術(shù)，也是學(xué)習(xí)流行唱法的學(xué)生必須掌握的技能，現(xiàn)總結(jié)出以下幾點(diǎn)，供大家參考，希望對(duì)大家的比賽有所幫助。</span> </p> <p> <span style="font-size:16px;">1。麥克風(fēng)一般與身體保持約45-60度角，斜向下方向，離嘴約兩厘米距離的地方(也可根據(jù)舞臺(tái)反送音箱音量大小、混響大小決定話筒離嘴之間的距離 ) 。</span> </p> <p> <span style="font-size:16px;">2。流行音樂(lè)演唱中，如果其他設(shè)備不做調(diào)試變化的情況下(如調(diào)音臺(tái)、功放機(jī)等)，演唱者如感覺(jué)聲音從音響設(shè)備傳出低音共鳴不足，可把麥克風(fēng)離嘴巴近一些，補(bǔ)償演唱者的低音共鳴效果，這樣可讓演唱者低音更加渾厚具有磁性。</span> </p> <span style="font-size:16px;">3。演唱者在演唱歌曲副歌高音部時(shí)，為防止擴(kuò)音設(shè)備音頻過(guò)高產(chǎn)生失真爆音的現(xiàn)象，可將話筒與嘴之間的距離適當(dāng)拉遠(yuǎn)。</span> <p> <br /> </p> <p> <span style="font-size:16px;">4。演唱者演唱作品結(jié)尾時(shí)，為了給聽(tīng)眾結(jié)束而不唐突效果，可在尾音至落音時(shí)，將話筒離嘴漸進(jìn)拉遠(yuǎn)，從而達(dá)到完美結(jié)束效果。</span><span style="font-size:16px;"></span> 武漢bbs話筒哪個(gè)牌子好</p><p
