Respite from aircraft noise: high-level overview of journey on building our knowledge.

The need has been identified for an overall outcome of any co-ordinated airport research programme to work towards a better understanding of airports impact on QoL with a requirement to better understand the value (in terms of noise reduction and health outcomes) and effectiveness of the interventions airports make - this includes the provision of respite. Anderson Acoustics Ltd (funded by Heathrow Airport Ltd) has been consolidating current knowledge on respite, particularly in relation to airspace design. That work has essentially continued the journey towards understanding respite and its effective implementation, linking together past, current, and potentially future activities, providing timelines, signposting to other reports and work. This paper presents a highlevel overview of HAL's journey to date on building knowledge on respite. [ABSTRACT FROM AUTHOR]
