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.
與燃油車相比，電動汽車已經有幾個優勢。從燃料成本到零排氣管排放，但現在
一項新的研究可能證實電動汽車的另一個經常被忽視的優勢。
The quieter driving environment of an electrically driven vehicle can have
significant mental health benefits, according to a new brain monitoring study.
據一項新的大腦監測研究，電動車的安靜駕駛環境可以帶來顯著的心理健康好處。
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.
該研究由 York 大學的聲學專家 Dr. Duncan Williams 領導，是由LEVC（倫敦EV公司）
發起，該公司在倫敦經營電動計程車。
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.
他們所做的是在四名職業駕駛的頭上放置腦電圖，通常稱為“腦蓋”，他們都在
倫敦市中心工作，並在駕駛電動和柴油計程車時監控他們的大腦活動。
They claim that the results indicate that drivers are more focused, calmer,
and happier when driving the electric version of the taxi:
他們聲稱，研究結果表示駕駛電動版的出租車時司機更專注，更平靜，更快樂：
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
比駕駛柴油車時更專注
*駕駛在電動車中時記錄到更高水平的β腦電波活動，這表明活動濃度水平更高。
簡而言之，在駕駛電動計程車時，司機覺得更放鬆了 (這句亂翻，想不到怎麼翻好)
*當在等紅燈時這一點尤為明顯 - 這是倫敦計程車司機常見的情況
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.
比駕駛柴油車時更平靜
*駕駛電動計程車時的心跳率一直較柴油計程車少，表示心理安寧程度更高
*與柴油計程車相比，電動計程車的工作環境噪音整體上低了 5dB，震動也較少
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
比駕駛柴油車時更快樂
*額外的司機調查數據顯示，最大的改善是幸福感增加
*減輕了壓力並減少了分心
Dr. Williams also commented on the findings of the study:
Dr. Williams 還評論了這項研究的結果：
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.
這項研究證明非常有趣。司機們都表示，在電動計程車中比在舊的柴油車型中更平靜，
減壓和更快樂。傳統上，這些感覺會與更多的 Alpha 腦波相關聯，這是一個放鬆的好指
標。 但是當我們查看數據時，看到了司機們有更多的 Beta 腦波，這是心理活動和注意力
的指標。
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.
這是什麼意思？這項研究表明，更安靜的駕駛環境讓駕駛處於更加集中的心理狀態。
換句話說，通過消除吵鬧的柴油發動機的隆隆聲，他們或許能夠以更有針對性但冷靜
的方式開始駕駛。這是一個非常吸引人的結果，鑑於電動商用車的發展，電動汽車帶來
的好處甚至超過了我們以前的想像。
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/說明：
很多人握上方向盤就會變了一個人，這或許也是跟壓力有關
不僅僅是車子噪音帶來的壓力，更多的應該是其他車子帶來的壓力(例如三寶)
但要是能減輕車子震動與噪音所帶來的壓力，對駕駛來說那應該也是非常有幫助
