Electric vehicles already have several advantages over gas-powered cars. From
no fuel cost to zero tailpipe emission, but now a new study might confirm
another often overlooked advantage of EVs.
与燃油车相比，电动汽车已经有几个优势。从燃料成本到零排气管排放，但现在
一项新的研究可能证实电动汽车的另一个经常被忽视的优势。
The quieter driving environment of an electrically driven vehicle can have
significant mental health benefits, according to a new brain monitoring study.
据一项新的大脑监测研究，电动车的安静驾驶环境可以带来显著的心理健康好处。
The study was led by acoustics expert Dr. Duncan Williams of the University
of York and ordered by LEVC (London EV Company), which makes the electric
black cabs operating in London.
该研究由 York 大学的声学专家 Dr. Duncan Williams 领导，是由LEVC（伦敦EV公司）
发起，该公司在伦敦经营电动出租车。
What they did is place an electroencephalogram, often referred to as a ‘
brain cap’, on the head of four professional cabbies who all operate in
central London and monitor their brain activity as they drove both the
electric and diesel black cabs.
他们所做的是在四名职业驾驶的头上放置脑电图，通常称为“脑盖”，他们都在
伦敦市中心工作，并在驾驶电动和柴油出租车时监控他们的大脑活动。
They claim that the results indicate that drivers are more focused, calmer,
and happier when driving the electric version of the taxi:
他们声称，研究结果表示驾驶电动版的出租车时司机更专注，更平静，更快乐：
More focused than when driving the diesel vehicle
* Higher levels of beta brain wave activity were recorded by drivers in the
electric vehicle, which indicates higher levels of active concentration. In
short, while driving the electric taxi, drivers were freed up get on with
driving
* This was particularly noticeable when vehicles are waiting at traffic lights
– a common situation for the London cabbie
比驾驶柴油车时更专注
*驾驶在电动车中时记录到更高水平的β脑电波活动，这表明活动浓度水平更高。
简而言之，在驾驶电动出租车时，司机觉得更放松了 (这句乱翻，想不到怎么翻好)
*当在等红灯时这一点尤为明显 - 这是伦敦出租车司机常见的情况
Calmer than when driving the diesel vehicle
* Heart rate was consistently less variable in the electric taxi than the
diesel taxi, indicating greater mental calmness
* The electric taxi was a less noisy working environment for the drivers with
around 5dB less overall amplitude, and an increased dynamic range in
comparison to recordings from the diesel taxi.
比驾驶柴油车时更平静
*驾驶电动出租车时的心跳率一直较柴油出租车少，表示心理安宁程度更高
*与柴油出租车相比，电动出租车的工作环境噪音整体上低了 5dB，震动也较少
Happier than when driving the diesel vehicle
* Additional driver survey data showed that the largest improvement over the
diesel taxi reported by the drivers was increased happiness
* This was followed by reduced stress and less distraction in the electric taxi
比驾驶柴油车时更快乐
*额外的司机调查数据显示，最大的改善是幸福感增加
*减轻了压力并减少了分心
Dr. Williams also commented on the findings of the study:
Dr. Williams 还评论了这项研究的结果：
This study proved hugely interesting. The drivers all reported being calmer,
less stressed and happier in the electric taxi than in the old diesel model.
Traditionally those feelings would correlate with more Alpha brain waves,
which are a good indicator of relaxation. But when we looked at the data, the
drivers’ showed more Beta brain waves, an indicator of mental activity and
attention.
这项研究证明非常有趣。司机们都表示，在电动出租车中比在旧的柴油车型中更平静，
减压和更快乐。传统上，这些感觉会与更多的 Alpha 脑波相关联，这是一个放松的好指
标。 但是当我们查看数据时，看到了司机们有更多的 Beta 脑波，这是心理活动和注意力
的指标。
What does this mean? Well, the study suggests that the quieter driving
environment allowed cabbies to be in a more concentrated state of mind. In
other words, by removing the noisy diesel engine rumble, they are perhaps
freed up to get on with driving in a more focused, but calm way. It’s a
fascinating result and, given the movement towards electric commercial
vehicles, shows there are even more benefits of going electric than we might
have previously thought.
这是什么意思？这项研究表明，更安静的驾驶环境让驾驶处于更加集中的心理状态。
换句话说，通过消除吵闹的柴油发动机的隆隆声，他们或许能够以更有针对性但冷静
的方式开始驾驶。这是一个非常吸引人的结果，鉴于电动商用车的发展，电动汽车带来
的好处甚至超过了我们以前的想像。
They say that all the drivers already had driven many miles in the electric
TX taxi and were familiar with its controls and driving behavior.
心得/说明：
很多人握上方向盘就会变了一个人，这或许也是跟压力有关
不仅仅是车子噪音带来的压力，更多的应该是其他车子带来的压力(例如三宝)
但要是能减轻车子震动与噪音所带来的压力，对驾驶来说那应该也是非常有帮助
