“We’ve become so accustomed to noise, there’s almost a deepprejudiceagainst the ideathatsilencemight be beneficial. If you tellsomeone to be quiet, you soundlike an old man. But it’s neverbeenmoreimportant to findcontinuingquiet. Silencefocuses us, improves our health, and is a key to lastingpeace and satisfaction.”
“We need to excitepeopleabout the sounds you start to hear if you merelyquietthingsdown a little. During a Japanese tea ceremony, the smallestsoundsbecome a kind of art—the spoonsmaking a lightringingsound on a bowl, the edges of a kimono （和服）brushingagainst the floor.”
“Deafpeople are veryattentive（专注的）in almosteveryaspect of life. If two deafpeople are walkingtogether, usingsignlanguage, theyconstantlywatch out for eachother and protecteachother by payingsteadyattention to the other. They are connected yet alsofullyaware of theirsurroundings. Evendeafteenagers! We in the hearingworld can learnfromthem. If we remove the powerfulblasts（一阵阵）of noise, we becomeaware of an extraordinarilyrichworldaround us—of littlesoftsounds and the sound of footsteps, of birdsongs and ice cracking（开裂声）. It’s astonishing how beautifulthingssoundwhen you can reallylisten. ”
