I went through the 'pager era' in the 70s and 80s. It was always most annoying when in a group and a pager went off. Whose was it? We would all be reaching for our pagers to see it it was us. The same thing happened when 'the small-brick' mobile phones came in around the late 80s to early 90s. Finally, we eventually got phones with selectable ringtones around the mid 90s. I have always since then used a personal ringtone that is different from anybody else's. And no, I don't put it on 'silent' because a lot of the time I don't have it in my pocket.
