In the past, we've done studies on the effects of traffic noise on sleep, and research subjects would often wake up in the morning and say, \"Ah, I had a wonderful night, I fell asleep right away, never really woke up.\"
Sebelumnya kita pernah meneliti efek suara lalu lintas terhadap tidur, dan subjek penelitian sering terbangun di pagi hari dan mengatakan \"Ah, malam saya menyenangkan, saya langsung tertidur, dan tidak pernah terbangun.\"
