HA Acoustics were engaged to undertake a feasibility study for a development of 3 houses, close to Plymouth Airport, Devon (currently not used for commercial aviation).
At the outset the PlymouthPublic Protection Officer requested that any build be in accordance with BS8233. so as to provide sound insulation against externally generated noise. HA Acoustics, recommended a design standard for roof, ceilings, walls and glazing to ensure that the internal noise criteria be met.
With no aircraft flying into the airport, HA Acoustics predicted typical free-field noise levels for site boundary and representative of closest noise sensitive receptors and compared these to the internal BS8233 criteria.
Though Plymouth airport is not currently used for aviation (see photo!), the glazing calculation determined the appropriate Sound Reduction Index. This required a minimum glazing specification of 6mm and 10mm glass separated by a 10mm airspace be used, with acoustic trickle ventilation units fitted to the windows on the airport facing façade.
