Then they seemed so familiar with french names and french authors : but my amazement reached its climax when miss temple asked helen if she sometimes snatched a moment to recall the latin her father had taught her, and taking a book from a shelf, bade her read and construe a page of virgil ; and helen obeyed, my organ of veneration expanding at every sounding line
隨后她們似乎對法國人名和法國作者了如指掌。但最使我驚訝的是,這時坦普爾小姐問海倫是不是抽空在復習她爸爸教她的拉丁文,還從書架上取了一本書,吩咐她朗讀和解釋維吉爾的一頁著作,海倫照著做了。我每聽一行朗朗的詩句,對她也就愈加肅然起敬。 -

A natural sounding headphone should have a gentle hump in the bass ( about 3 or 4 db ) between 40hz and 500hz. ( this compensates for the fact that headphones don ' t give you the physical punch that the sound from a speaker has ; so a slight compensation of increased bass is needed for natural sound. ) headphones also need to be rolled off in the highs to compensate for the drivers being so close to the ear ; a gently sloping flat line from 1khz to about 8 - 10db down at 20khz is about right
這大致是說,耳機頻響曲線在低頻40 - 500赫茲間有個小的隆起是正常的,因為耳機不能象喇叭那樣給人真實的低頻沖擊力,所以在這個低頻段加強一些,聲音反而自然逼真些.另外,為避免太刺激耳朵,耳機在1000赫茲起到耳朵聽力的極限20000赫茲間應該有衰減,到2萬赫茲處比平均輸出低8 - 10分貝是正常現象
