The Mayor’s Ambient Noise Strategy
opportunities that prevent people who have impairments from taking part
in the life of the community on an equal level with others due to physical
and social barriers.’
Disabled person A disabled person is someone who has an
impairment, experiences externally imposed barriers and self-identifies
as a disabled person.
Easterly operations When aircraft make their final approach to land
from the west, and take off towards the east.
Easterly preference A mode of operation at Heathrow which would
mean that aircraft would maintain easterly operations when there was a

EPNdB Effective Perceived Noise decibel; a metric used internationally in
the noise certification of aircraft.
Entertainment Management Zone (EMZ) An area where agencies
work together to tackle issues associated with the evening and night-time
economy. An EMZ can be designated in areas where there is a
concentration of entertainment activities, or in locations where growth of
entertainment uses is planned.
Environmental noise The European Environmental Noise Directive
2002/49/EC defines ‘environmental noise’ as ‘unwanted or harmful
outdoor sound created by human activities, including noise emitted by
means of transport, road traffic, rail traffic, air traffic, and from sites of
industrial activity.’
Environmentally Enhanced Vehicle (EEV) A potential new category,
particularly for heavy vehicles, with quieter and cleaner engines, control
of body rattle and other incidental noise, including loading/unloading.
Equal energy principle Implicit in the L eq
measure (see above) is that,
within certain limits and in certain contexts, a smaller number of louder
events, or a larger number of quieter events, may have similar effects in
terms of human response.
Evening Generally taken as the period between 1900 and 2300 hours.
