为什么⼀听到某些⾳乐你就会不由⾃主地想跳起舞来？⼀项新研究表明，这和⾳乐⾥的低⾳有关，研究⼈员发现，在⾳乐会期间加⼊更多的低⾳会让⼈更多地随⾳乐起舞。相关结果发表在《当代⽣物学》（Current Biology）杂志上。“从很⼩的时候起我就对⾳乐和⾳乐节奏⼗分着迷，特别是它们带给⼈们的感觉。
”加拿⼤⻨克⻢斯特⼤学（McMaster University）的博⼠后研究员丹尼尔·卡梅伦（Daniel Cameron）说，他同时也是个⿎⼿，“作为⼀名⿎⼿，你感兴趣的是如何让⼈群律动起来，⼼情愉悦，沉浸享受。这就涉及到了我的科学研究领域。”卡梅伦和同事想弄明⽩，⾳乐是如何让我们的身体产⽣⼏乎⽆法抑制的冲动来随之律动的：“基于各种故事和实验证据，我们发现低⾳和起舞之间存在⼀定关联。
”喜欢电⼦舞曲（EDM）的⼈表示，持续的低⾳会产⽣⼀种让他们想要随之律动的感觉，⽽⼀些研究表明，在锚定低⾳⾳符时，我们的动作节奏会更准确。“例如，如果你让⼈们跟着低⾳打节拍，他们的拍⼦会更准确⼀点，更⼀致⼀点。”因此研究⼈员开始实验：“如果你在⾳乐中加⼊更多的低⾳，会引发更多的起舞吗？”他们不想以⼀种显⽽易⻅的⽅式对低⾳进⾏操纵，因为那样做⼈们可能会有意识地增加他们的舞动。
“那可能会很有趣……”但也会混淆实验结果，这就好像药物试验中的受试者知道他们⽤的是真药⽽不是安慰剂⼀样。卡梅伦表示：“我们想做⼀种微妙的操纵，⼀种⾮常难被察觉的操纵。”他们搞出了⼀套⾮常⾮常低频的喇叭。“这些是⾮常专业的扬声器，有点像低⾳炮。低⾳喇叭常常作为⽴体声系统的⼀部分，它们播放的频率低于⼤多数系统所能播放的频率，甚⾄⽐我们通常能够听到的频率还要低。
”研究⼈员设置了这些特殊的扬声器，举办了⼀场⾳乐会，邀请电⼦⾳乐⼆重奏Orphx去到他们的LIVELab，这⾥的“LIVE”是“large, interactive virtual environment”，即……[查看全⽂]It's the Bass That Makes Us Boogie Karen Hopkin: This is Scientific American’s 60-Second Science. I’m Karen Hopkin. Hopkin: Ever notice that some music just really makes you want to dance? Well, a new study shows that it is, indeed, all about the bass. Because researchers have found that, during a concert, boosting the bass bumps up the boogying. The results appear in the journal Current Biology. Daniel Cameron: Music and musical rhythm have been kind of fascinating to me for a long time, since I was a kid. In particular, the way that they make us feel. Hopkin: Daniel Cameron is a postdoctoral fellow at McMaster University. He also plays drums. Cameron: As a drummer, you’re interested in making the crowd want to move and feel good and give a good pleasurable time feel. And this is related to the work I do in science. Hopkin: Cameron and his colleagues want to understand how music can engender an almost irrepressible urge to feel our bodies in motion. Cameron: And we knew from anecdotal evidence and other experimental evidence that there was an association between bass and dancing. Hopkin: So, people who enjoy electronic dance music, or EDM, report that the thrumming bass produces a sensation that makes them want to move. And some studies have shown that our movements are more fine-tuned when we’re locked onto bass notes. Cameron: So, for example, if you have people tap along to a sequence of tones, their tapping is slightly more accurate, they’re more synchronized…when those tones are low in frequency compared to high in frequency. Hopkin: So the researchers set out to determine: Cameron: If you add more bass to music, will it cause more dancing? Hopkin: Now, they didn’t want to manipulate the bass line in a way that was obvious. Because then people might consciously decide to step up their stepping out. Cameron: That might be interesting…Hopkin: But it would also muddy the results…like if someone in a drug trial knows they’re getting the real deal and not a placebo. Cameron: So we wanted to do a subtle manipulation, a very consciously undetectable manipulation. Hopkin: So they broke out a set of very very low frequency speakers. Cameron: These are specialized speakers. Kind of like sub-subwoofers. People might have subwoofers as part of their stereo system. And these are speakers that play even lower frequencies than most systems are able to do. Even lower frequencies than we think are typically able to be heard. Hopkin: With their special speakers set up, the researchers staged a concert. Cameron: We had the electronic music duo Orphx come to our LIVELab. Hopkin: That’s LIVE…L-I-V-E…for large, interactive virtual environment. It’s like a...[full transcript]“论⽂信息Cameron, D.J. et al.
