  1. 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
