But the first time you catch an edge and go clunk !
但是你第一次捕捉到一个优势，走
My head goes clunk on the floor , and I suddenly regret not locking the door .
我的头去弹响在地板上，我突然后悔没有锁门。
To produce the ideal clunk , car doors are designed to minimise the amount of high frequencies produced ( we associate them with fragility and weakness ) and emphasise low , bass-heavy frequencies that suggest solidity .
