A bizarre experiment in soundless music has revealed how people’s emotions are affected by noises they cannot hear.



Scientists have begun analysing the responses of 250 people who took part in the study into the effects of infrasound, carried out at Liverpool’s Metropolitan Cathedral last September.



They showed the audience’s emotions intensified as the inaudible sound vibrations, too low for the human ear to perceive, were blasted out during a 50-minute piano recital.
