- The results showed that the OSB wallbord composed by OSB,air and glass wool had a good sound absorption property,specially for low frequency sound. 結果表明，由定向結構板、空氣層、玻璃棉構成的復合墻體在低頻率范圍內會(huì )出現共振現象，吸聲性能比單層定向結構板有顯著(zhù)的增加，但在高頻率范圍內變化較??；
- This is the EQ frequency sound effects, change pitch without altering the reason that everyone (especially beginners) can be assured that the use of EQ. 這就是EQ效果器能改變聲音頻率而不改變音高的原因，所以大家（尤其是初學(xué)者）大可放心地使用EQ。
- The Yule log was either dragged by the people of one farmstead or several neighbours together. This was accompanied by songs, singing games, and various sounding instruments. 屆時(shí)由某個(gè)家庭的成員或幾家鄰居共同拖拉圣誕節原木,伴有歌聲、唱歌游戲和各種聲樂(lè )器具。
- By turning up the volume of those high frequency sound waves, and focussing them carefully, they can sometimes break up a tumor inside the body, without surgery. 通過(guò)控制這些高頻率聲波的量，仔細對準它們，有時(shí)它們能夠殺死身體內的腫瘤，而不用開(kāi)刀。
- But the timbres present obvious difference;they differentiate into single timbre, dual timbre and complex timbre with a low frequency sound of high amplitude. 但是音色有明顯的差異,即分別為單音色、雙音色和具有高幅低頻聲的復合聲。
- During this process heat energy first converts to unorderly sound waves, then to high frequency sound waves, finally ends up with low frequency sound waves. 這一過(guò)程中能量的轉化是先從熱能到雜亂的聲波，接著(zhù)轉化為高頻聲波的能量，然后完成從高頻能量到低頻能量的轉化，直到整個(gè)系統的穩定。
- This echolocation, where high frequency sounds bounce off objects giving the bat a picture of the world around it, is purely functional. 回聲定位其實(shí)屬于工作用語(yǔ)，蝙蝠利用從物體反彈回來(lái)的超聲波，對周?chē)澜缬袀€(gè)大致了解。

- While high frequency sounds tend to be more hazardous and more annoying to hearing than low frequency sounds,most noise pollution damage is related to the intensity of the sound. 雖然高頻聲音比低頻聲音更加危險且惱人，大多數的噪音污染損害卻與聲音強度有關(guān)。
- This breed is also known for his ability to foretell storms and avalanches, perhaps because he may hear very low frequency sounds that are beyond our ability to hear. 這個(gè)品種有能力預測風(fēng)暴和雪崩,可能是因它們能聽(tīng)見(jiàn)非常低的頻率,甚至低于我們能力所能聽(tīng)到的。
