Can you hear This?
When something creates a sound wave in a room or an auditorium, listeners hear the sound wave directly from the source. They also hear the reflections as the sound bounces off the walls, floor, and ceiling. These are called the reflected wave or reverberant(反射的)sound, which can be heard even after the sound is no longer coming from the source.
The reverberation time of an auditorium is determined by the volume or interior size of the auditorium. It is also determined by how well or how poorly the walls, ceiling, floor, and contents of the room (including the people) absorb sound. There is no ideal reverberation time. Because each use of an auditorium calls for different reverberation. Speech needs to be understood clearly: therefore rooms used for talking must have a short reverberation time. The full-sound performance of music such as Wagner operas or Mahler symphonies should have a long reverberation time. The light, rapid musical passages of Bach or Mozart need a reverberation time somewhere between.
Acoustic problems often are caused by poor auditorium design. Smooth, curved reflecting surfaces create large reflections. Parallel(平行的)walls reflect sound back and forth, creating a rapid, repetitive pulsing effect. Large pillars(柱)and corners can cause acoustic shadows as the sound waves try to pass around the object. Some of these problems can be solved by using absorbers and reflectors to change the reverberation time of a room. For example, hanging large reflectors, called clouds, over the performers will allow some sound frequencies to reflect and others to pass to achieve a pleasing mixture of sound.

Mt. Desert IslandThe coast of the State of Maine is one of the most irregular in the world.A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles.If you followed the coastline between these points,you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline._________(46)At that time,the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier（冰川）descended , however , it expendedenormous force on those mountains,and they sank into the sea.As the mountains sank,ocean water charged over the lowest parts of the remaining land,forming a seriesof twisting inlets and lagoons（咸水湖）.The highest parts of the former mountain range,nearest the shore, remained as islands._________(47)Marine fossils found here were 225 feet above sea level,indicating thelevel of the shoreline prior to the glacier.The 2,500-mile-long rocky coastline of Maine keeps watch over nearly two thousand islands. Many of these islands are tiny and uninhabited,but many are home to thriving communities.Mt. Desert Island is one of the largest,most beautiful of the Maine coast islands.Measuring 16 miles by 12 miles.Mt.Desert was essentially formed as two distinct islands._________(48)For years,Mt. Desert Island,particularly its major settlement,Bar Harbor,afforded summer homes for the wealthy.Recently though,Bar Harbor has become a rapidly growing arts community as well.But,the best part of the island is the unspoiled forest land known as Acadia National Park.Because the island sits on the boundary line between the temperate（温带）and sub-Arctic zones , the island supports the plants and ani- mals of both zones as well as beach , inland , and alpine（高山的）plants. _________( 49 ) The establishment of Acadia National Park in 1916 means that this natural reserve will be perpetually available to all people,not just the wealthy.Visitors to Acadia may receive nature instruction from the park naturalists as well as enjoy camping,cycling,and boating. Or they may choose to spend time at the archeological museum,learning about the Stone Age inhabitants of the island.The best view on Mt.Desert Island is from the top of Cadillac Mountain._________(50)From the sum- mit,you can gaze back toward the mainland or out over the Atlantic Ocean and contemplate the beauty created by a retreating glacier._________(49)A:This mountain rises 1,532 feet,making it the highest mountain on the Atlantic seaboard.B:It is split almost in half by Somes Sound,a deep and narrow stretch of water,seven miles long.C:The wealthy residents of Mt.Desert Island selfishly kept it to themselves.D:Mt. Desert Island is one of the most famous of all the islands left behind by the glacier.E:The term comes from the activity of the ice age.F: It also lies in a major bird migration lane and is a resting spot for many birds.
