据英国《每日邮报》报道，位于英国伦敦的希思罗机场近日做了一项噪音调查。结果显示，在所有降落在希思罗机场的航班中，波兰航空公司的飞机噪音最大。
为了降低机场的噪声污染，希思罗机场的抗噪音组织发起了一项名为“静音航空”的活动。通过对今年7月至9月所有在该机场降落的飞机进行监控，分析人员将不同航空公司的噪音指数按照六项指标进行排列。
除了波兰航空以外，噪声污染最严重的十家航空公司还有：以色列航空、泰国航空、土耳其航空长途航线、南非航空、欧洲航空运输公司、芬兰航空、俄罗斯航空短途航线、爱琴海航空以及埃及航空。
相反，噪音最小的航空公司包括：英国航空短途航线、维珍航空国内线、爱尔兰航空、美国航空、澳洲航空、阿联酋航空、美国联合航空、美国达美航空、荷兰皇家航空以及德国汉莎航空。
所有航空公司中， 80%都达到了希思罗机场的最低噪音要求，其中94%至少达到六项指标中的五项。希思罗机场表示，飞机新旧程度以及飞行方式是造成噪音水平差异的重要因素。快速降落比缓慢降落产生的噪音要小很多。
希思罗机场抗噪音组织负责人约翰•斯图尔特表示，“我们很支持机场进行的反噪音行动，这是治理机场噪声污染具有建设性的一步。”这项反噪音行动源于希思罗机场意图再增建两条跑道，而航班噪音是机场周边社区居民是否同意扩建的最大因素。
That's a LOT of noise: Noise survey of 50 carriers landing at Heathrow finds Polish airline is the loudest
Polish planes landing at Heathrow are the loudest the first ever ‘league-table’ of airline noise reveals today.
By contrast, British Airways’ short-haul services are the quietest new data released as part of Heathrow’s new ‘Fly Quiet’ programme shows.
The worst offender is Polish airline LOT, in last place, just ahead of Israeli carrier national El Al in 49th place and Thai Airways in 48th place.
The initiative aims to name and shame airlines into putting a wind-sock in it.Virgin Atlantic's Little Red domestic service was in second place behind BA, with Irish airline Aer Lingus in third.
British Airways’ long-haul flights were outside the top-ten - in twelfth place just behind TAP Portugal.
Those keeping most people awake at night at the bottom of the table were: Turkish Airlines long-haul, South African Airways, European Air transport, Finnair, and Russia’s Aeroflot short-haul.
The scores were based on noise levels during the period July to September and are given a ‘traffic light’ style rating for various categories and timings of noise.
Of the listed airlines, 80 per cent met Heathrow's minimum requirements on noise, with 94 per cent meeting at least five of the six categories.
Heathrow said a combination of old, nosier planes, and the way in which it is flown are key factors in noise levels.
A steep descent to the runway also leaves less of a noise ‘footprint’ than a longer steady descent.
Heathrow sustainability director Matt Gorman said: 'We are at the forefront of international efforts to tackle aircraft noise and are committed to continuing to reduce the number of people affected by noise.
‘The launch of the Fly Quiet programme signals our firm commitment to being transparent about aircraft noise and our progress in reducing its impact on local communities whilst still safeguarding the vital connectivity and economic growth that Heathrow provides.’
John Stewart, chairman of the Heathrow anti-noise and extra runway campaign group Hacan, said: ‘We welcome this initiative from Heathrow. It is a constructive move to improve the noise climate.’
BA head of environment Jonathon Counsell said: ‘We are very pleased that our short-haul fleet has proved itself the quietest at Heathrow, and we know we can do more.
'Overall, we have a noise reduction target to reduce the average noise per flight by 15per cent by 2018.’
He added: ‘This autumn we have introduced nine new long-haul aircraft, all of which are significantly quieter than their predecessors, and we will take delivery of more than 30 further aircraft in the next three years.’
The findings come as ‘noise’ remains one of the biggest factors affecting whether Heathrow will get a controversial third ? or even a fourth ? runway.(MailOnline
