又稱為訊噪比,即放大器的輸出信號的電壓與同時輸出的噪聲電壓的比,常常用分貝數表示。設備的信噪比越高表明它產生的雜音越少。一般來說,信噪比越大,說明混在信號里的噪聲越小,聲音回放的音質量越高,否則相反。Film 35 mm ; preamplifier for optical sound, general data for measuring

電子放大器也可以使音量大到極至,音樂顯得洪亮而有穿透力,震耳欲聾,因而達到一種徹底的效果,使得聽眾不再是被動的接受者,而是完全地投入,用整個身心去感受音樂。A large planar microphone array, which consists of 111 microphones, was successfully applied to obtain a two - dimensional mapping of the sound sources on a landing aircraft. the focus of study in this paper is on the landing gear noise source. the spectra, directivities and sound pressure levels of flap side - edge noise of 7 narrow - board commercial aircraft and 7 wide - board commercial aircraft are presented. it is found that the landing gear noise spectrum is broadband with some single tones in some cases. the directivity of the total sound pressure level of a landing gear noise resembles that of a horizontal dipole. the level differences between the various aircraft landing gears are larger than those expected from the airspeed differences. it is thus expected that the louder noise emission of the landing gears can be reduced by redesigning
應用由111個傳聲器組成的平面傳聲器陣列對當前流行的民用客機進場著陸過程中的機體噪聲源進行了實驗測量,本文對七架窄體客機和七架寬體客機的起落架噪聲進行了分析,得到了起落架噪聲的頻譜特性、指向特性和聲級變化.研究發現,起落架噪聲的頻譜是由寬頻隨機噪聲與一些較為明顯的單音噪聲源組成,起落架噪聲的指向性類似於一個水平放置的偶極子.不同飛機起落架噪聲的聲級相差較大,這說明可以通過重新結構設計降低起落架噪聲。This is a low impedance discrete level control which sits between the preamp active circuitry and the input to your power amplifier

由此產生的數據量太大以至不可能存儲在一張cd盤上,於是hdcd編碼器分析了這個高度解析的訊號,來決定當訊號轉化為16bit 44 . 1khz成的訊號儲存在一張cd上時,有哪些音樂方面的訊息將丟失。然後編碼器輸出一個16bit 44 . 1khz的數碼音訊號,在其第16bit有一個隱藏的控制代碼,這個隱藏的聽不見的控制代碼在cd播放器里告訴hdcd解碼器運行某些有關聲音訊號的程序來恢復一些當初在高解析數碼訊號中表現出來的訊息,解碼時可以產生巨大的聲音訊號的變化。這個控制代碼是一種解碼器可以識別的速寫方式。First, turn down the volume on the amplifier. the volume should be set to minimum before you begin playing the program source
