They put on their headphones, drape a hood over their head and drift off into the world of "digital highs." Videos posted on YouTube show a young girl freaking out and leaping up in fear, a teenager shaking violently and a young boy in extreme distress. This is the world of "i-Dosing," the new craze sweeping the Internet in which teenagers used so-called "digital drugs" to change their brains in the same way as real-life narcotics (毒品). They believe the repetitive drone-like music will give them a "high" that takes them out of reality, only legally available and downloadable on the Internet. Those who come up with the "doses" claim different tracks mimic different sensations you can feel by taking drugs like Ecstasy (迷幻药). The reactions have been partially sceptical but some songs have become wildly popular, receiving nearly half a million hits on YouTube.
There has been such alarm in the US that the Oklahoma Bureau of Narcotics and Dangerous Drugs has issued a warning to children not to do it. "Kids are going to flock to these sites just to see what it is about and it can lead them to other places," spokesman Mark Woodward said. He added that parental awareness is key to preventing future problems, since i-Dosing could indicate a willingness to experiment with drugs. Schools in the Mustang area recently sent out a letter warning parents about the new trend after several high school students reported having physiological effects after trying one of these digital downloads.
I-Dosing tracks have imposing names such as "Gates of Hades" or "Hand of God" which are ten minutes long—some sound like a ship’s horn being repeated again and again whilst others are more rough and resemble cheap synthesizers (电声合成器)being played very fast. But although they use a very modern method of spreading themselves, i-Dosing is actually a variation on a very old method of achieving an altered state. In 1839 German physicist Heinrich Wilhelm Dove found that two tones played at slightly different frequencies in each ear makes the listener think they are hearing a quick beat. He called the phenomenon "binaural beats," and it has been the subject of research in the two centuries since.
This therapy is used in clinical settings to research hearing and sleep cycles, to induce various brain wave states, and treat anxiety. Dr. Helane Wahbeh, a Naturopathic Physician and Clinician Researcher at the Oregon Health and Science University, said: "Binaural beats happen when opposite ears receive two different sound waves. And normally, the difference in sound between each ear helps people get directional information about the source of the sound. But when you listen to these sounds with stereo headphones, the listener senses the difference between the two frequencies as another beat that sounds like it’s coming from the inside of the head." [br] What did German physicist Heinrich Wilhelm Dove find about i-Dosing?
选项
A、It is actually a kind of brain wave used by researchers.
B、It is a matter of the brain interpretation of mismatched frequencies.
C、It offers a sense of high by varying brain wave states.
D、It lacks scientific foundation to say that binaural beats function as drugs.
答案
B
解析
细节推断题。根据定位句可知,德国物理学家Dove发现,如果分别在两只耳朵边播放频率上稍有不同的音调,听者可能觉得他们听到的是一种快速的节拍,他把这一现象称之为“立体声节拍”。据此可以推断,这不过是人脑对于两种音频的解读,因此答案为B)。
