In the past, sound engineers worked in the back rooms of recording studios, but many of today’s sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound. Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can’t let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device(LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.

Passage 2(2020天津第一次统考,D) Studying a subject that you feel pointless is never a fun or easy task. If you’re studying history,
asking yourself the question “why is history important” is a very good first step. History is an essential part of human civilization. You will find something here that will arouse your interest, or get you thinking about the significance of history. History grounds us in our roots. History is an important and interesting field of study, and learning the history of our home country can give us a deeper, more meaningful glimpse (一瞥) into our ancestral pasts, and how we got to where we are today. Many people feel like they need a sense of cultural belonging, which is something that studying your roots and being open-minded to the evolution of your culture can provide. History enriches our experience. Reading history is an amazing experience because it enables us to reflect on the social and economic life of the people living long time ago. According to the experts, problems faced by people regardless of the past and present are the same. With the information about the ancestors, one can become more experienced in handling challenges of life.
For those who hunger for some peace and quiet, sound can now create silence. Let’s say you are at the airport, and the little boy on the seat next to you is humming(哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine on, point it at the target, and your peace and quiet comes back. Directed sound is a new technology that allows companies to use sound in much the same way spotlights(聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, a “spotsound” creates a circle of sound in one targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.
C.They can be transformed into energy.
D.They can be directed onto a specific area.
4.Directed sound can be used for
.
A.creative designs of restaurant menus
C.block the incoming sound waves
D.stop unwanted sound from affecting you
3.What feature do spotsounds and spotlights share?
A.They travel in circles.
B.They clear the atmosphere.
B.ideal sound effects on the theater stage
C.different choices of music for businesses
D.strict control over any suspicious customer
