This report covers the development of a process to estimate background ambient noise from road traffic and railway noise estimates undertaken for Defra. These estimates were then compared against background ambient noise levels measured near London Heathrow and Gatwick airports, utilising data from the airports’ noise monitoring systems when specific noise monitors were not being overflown by aircraft.
