Almost all of the research on sonic booms and their effect on residential noise levels was done in the 1950s.
Our knowledge of transonic aerodynamics and aircraft design have improved considerably sense then and much of the "common" knowledge that sonic booms will shatter windows and disrupt everyday life as a plane flies overhead at cruising altitude are very much outdated.

- gsnedders 6y agoConcorde didn't fly over London at supersonic speeds, and I doubt it often flew over London a cruise altitudes. The problem with Concorde on approach/departure was largely a function of its engines, rather than speed. https://hansard.parliament.uk/Commons/1973-07-18/debates/4279b473-5235-41e3-923e-580f3df10e57/Concorde(NoiseLevels) https://hansard.parliament.uk/Commons/1973-07-18/debates/427... shows it was comparable to slightly older aircraft at the time of introduction (VC10, B707, DC8) but notably louder than what was arguably its biggest competitor (747-200). In later years, continued improvements in aircraft noise pollution meant the margin between Concorde and other aircraft operating out of LHR just grew larger and larger.
