The Muted speaker emoji is generally used to indicate that symbol when someone wants you to stop talking, stop playing your loud music, or make sure all electronic devices are silent before entering a quiet only zone.
NOTE: Muted Speaker was accepted in 2010 as part of Unicode 6.0 under the name “Speaker with Cancellation Stroke” and in 2015 labeled to Emoji 1.0.
