I noticed supermarkets in my area changed their in-shop audio ads to use screechy loudness-enhanced tone in recent years and attributed it to people like me wearing headphones becoming more frequent - the loudness-enhanced tone cuts through the headphones like a megaphone, thus forcing me again to hear the ads even with headphones.
