I do not think people realise, and it is happens regularly, the effect that the noise generated by phones located near recording equipment has on the people who are seated in front of me, in particular the person who must wear earphones. The noise is extremely annoying and irritating. If possible, when people are speaking or near a speaker, I ask everyone to please put their phones some place that does not affect the logistics. I do not blame the Leader. Interference with the recording equipment happens regularly.
