Letter ratio : point biggest not lose the signal strength of the true voice with at the same time of the emanative noise strength opposite voice for of ratio, usually with meaning, letter comparing more bigly, turn on electricitying the road more small, quality more pure and unadulterated. want to choose the letter the ratio in the product of above. new of summer is with the series the product s letter ratio all in the above, have more professional of performance
信噪比：指最大不失真聲音的信號強度與同時發出的噪音強度之間的比率，通常以表示，信噪比越大，功放電路的相對噪聲就越小，音質就越純正。要選信噪比在以上的產品。夏新和系列產品的信噪比都在以上，有更加專業的表現。Again call the the ratio, namely the electric voltage of the enlarger s exportation signal with at the same time output s voice ratio for electric voltage, usually use the decibel number to mean. the equipments s letter the ratio is more our output of high enunciation is more little. by any large, letter the ratio is more big, and the elucidation is in the in the signal a the quantity for more smallly, voice returning putting is more high, otherwise contrary. letter the ratio should be generally not lower than 70 dbs, high the letter of the true box the ratio should attain 110 dbs are above
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。Bender ' s report, published in the wildlife research journal, found that the animals " own alarm signal was much more effective at scaring off the eastern grey kangaroos targeted during tests than the artificial sounds, which they grew used to
