Electra, Viscount, Herald, F27, Shorts 330, Bandeirante, Trislander and Piper and Cessna twins made up the nightly mix in those days, plus British World BAC 1-11s and B707s at times. The Electra was noisy (and smoky) while the Viscount intake whine was something to behold but I don't remember much in the way of prominent noise complaints. It was the later runway extension plans that stirred up concerns in that quarter to a much greater extent.
