Sports Star Yao Ming

If YaoMing is not the biggest sports star in the world, he almost certainlythetallest. At 2.26m, he is the tallest player in the NationalBasketballAssociation (NBA) and holds the record as the most towering Olympianever to competein the Game.

But whatreally stands out about the giant center is his celebrity (名气). Few,if any, Chinese athletesare as well-known as Yao Ming around the world. Peopleacross the globe arefascinated with Yao, not only for his basketballprowess(接杰出的才能)but also for being a symbolof international commerce.

When Yaojoined the Houston Rockets as the No. 1 pick in the 2002 NBA draft hewas thefirst international player ever to be selected first.

When itwas announced in February that Yao would miss the rest of the NBAseason andpossibly the Olympics with a stress fracture (骨折)in his left foot, acollective shudder spread across China. Afterconsiderable debate and discussion,Yao opted to get his foot surgicallytreated in an operation that placed severaltiny screws across the bone, tooffer his overburdened foot more support. Thesurgery was a success, and thoughthe estimated four-month recovery period willleave him little time to preparewith Team China. Yao has vowed to be ready forthe Beijing Olympics.

Yaowrapped up a 10-day trip to China, where he underwent a series oftraditionalChinese medicine (TCM) treatments, hoping to accelerate his recoveryprocess.Western experts are generally skeptical of TCM’s benefits, althoughnewresearch from the University of Rochester suggests that a certaincompoundderived from shellfish may indeed stimulate bone repair.

“Thereis no reason to dismiss TCM, “ Yao told a press conference in Beijing.“It’sbeen used in our country for thousands of years. I don’t think that it’sshorton science.”

Can You Hear This?

When something creates a sound wave in a room or anauditorium, listeners hearthe sound wave directly from the source. They alsohear the reflections as thesound bounces off thewalls. floor, and ceiling. These are called the reflectedwave or reverberant(反射)sound, which can be heard evenafter the sound is nolonger coming from the source.

The reverberation time of an auditorium isdetermined by the volume orinterior size of the auditorium. It is alsodetermined by how well or how poorlythe walls, ceiling, floor, and contents ofthe room (including the people) absorbsound. There is no ideal reverberation time,because each use of an auditoriumcalls for different reverberation. Speechneeds to be understood clearly;therefore rooms used for talking must have ashort reverberation time. Thefull-sound performance of music such ad Wagneroperas or Mahler symphonies shouldhave a long reverberation time. The light,rapid musical passages of Bach orMozart need a reverberation time somewherebetween.

Acoustic problems often are caused by poorauditorium design. Smooth, curvedreflecting surfaces create large reflections.Parallel (平行的)wallsreflect soundback and forth, creating a rapid, repetitive pulsing effect.Large pillars (柱)andcomerscan cause acoustic shadows as the sound waves try to pass around theobject.Some of these problems can be solved by using absorbers and reflectorstochange the reverberation time of a room. For example, hanging largereflectors,called clouds, over the performers will allow some sound frequenciesto reflectand others to pass to achieve a pleasing mixture of sound.
