Large Hadron Collider: scientists create sound of ‘God particle’
Sounds set to be made by the subatomic ‘God’ particle at the Large Hadron Collider (LHC) have been simulated by scientists aiming to make the £6bn experiment more accessible.
聲音準備由大型強子對撞機（LHC）的亞原子'上帝'粒子發出，科學家已作模擬旨在使60億英鎊的實驗更加受到讚賞。

LHC聲音計劃的目的是讓在日內瓦歐洲粒子物理研究所的物理學家，去'聽'數據以圖更容易識別那關鍵的'希格斯玻色子'粒子。
Finding the Higgs boson – also known as the God particle – is the primary aim of the LHC experiment because it will provide an insight into the nature of all matter.
尋找希格斯玻色子 - 也被稱為上帝粒子 - 是LHC實驗的主要目的，因為它會為提所有物質的性質供一個深入了解。
It is hoped the subatomic particle will emerge from the 27km circular tunnel under the Swiss-French border where beams of proton particles are being smashed together.
它是希望亞原子粒子會從在瑞士和法國邊境的 27公里圓形隧道出現，在那裡質子粒子束會被一起粉碎。
LHC Sound, a collaboration of particle physicists, musicians and artists in London, has converted data expected from collisions into sounds in a process called sonification.
LHC的聲音是一個粒子物理學家、倫敦音樂家和藝術家的合作，已在一個被稱為可聽的過程轉換成數據，預期從碰撞變聲音。
The data was provided by the LHC's Atlas experiment which includes a calorimeter measuring the energy from collisions. The note and pitch of the sound varies with the amount of energy recorded.
數據是由LHC的ATLAS實驗提供，其中包括一個熱量計量度來自碰撞的能量，聲音的音符和音高會隨記錄的能量的數量變化。
LHC Sound is planning live performances of the data during the summer but early simulations of the particles can be heard here.
Dr Lily Asquith, one of the team, explained in a recent blog entry:
“Sound seems the perfect tool with which to represent the complexity of the data; our ears are superb at locating the source and location of sounds relative to one another, we can hear a vast range of frequencies and distinguish timbres (different instruments) before they have even played a full cycle.
“We also have an incredible ability to notice slight changes is pitch or tempo over time and to recognise patterns in sound after hearing them just once.
“A simple example of sonification is the car parking sensor that informs you of the space behind you via a beeping sound. The distance between you and the car behind you is mapped to the period of the sound, so that small distances produce a series of beeps that are very close together in time.”
LHC Sound was funded by the Science and Technology Facilities Council.
In a recent Q&A with the New Scientist blog, CultureLab, Dr Asquith explained the origins of the project.
"I was sitting in on a rehearsal with some musician friends in an improvisational electronic/brass band called WORM under a railway arch in Brixton," she said. "I was talking about particle physics to my long-suffering friend Eddie Real, a percussionist.
"I was actually doing impersonations of different particles and trying to get him to develop them on his electronic drum kit. Another band member, Ed, got very excited and asked if it would be possible to do this properly – extract sounds directly from the data.
"We asked the Science and Technology Facilities Council to fund a public engagement project to do just that, and they agreed."
On its website, the project states: "We want everyone to be able to share in the wonder and excitement of the greatest experiment ever built.
"We feel passionately that everyone is capable of appreciating what is happening at CERN and that it is the responsibility of those of us already `in the know' to find new and better ways of sharing the awe-inspiring magnificence of it all."
