Introduction: The noise emissions from the operation of heliports situated in cities can have significant adverse impacts on a large number of local residents. Despite its significance, the effect of noise from rotary aircraft operation in an urban setting has not been extensively studied. Objective: This paper presents for the first time an objective and subjective investigation into the noise emissions from the London Heliport and the associated impact on local residents. Method: Long-term noise monitoring measurements were taken at four locations and a social survey was implemented involving over 1500 respondents. A new objective measurement methodology was designed and developed that allowed individual air movements from the Heliport to be acoustically identified. Subjective results were contrasted with relevant social surveys and to the objective results. Objective results were also compared to planning guidance, local operation conditions and national and international based noise assessment criteria. Results: Excessive sound levels were found, both internally and externally, which can be attributed directly to the operation of the Heliport. The high participation rate obtained in the social survey confirmed that noise emissions from the heliport operation cause important/substantial adverse impact on quality or life and well-being of the majority of respondents. Conclusions: The level of annoyance reported by respondents appeared higher than the level of annoyance attributed to the noise measurements at monitoring sites. As a study first of its kind, it is expected that the findings will inform and influence future regulatory policy and consequently improve the well-being of many residents.
