This emoji goes beyond just a state of no sound; it can also express a strong intention of 'having nothing more to say' or 'I will remain silent'. Sending this emoji during an argument can be a signal that you want to end the conversation.

It's similar to using the 'mute' feature on social media when you no longer want to see someone's opinions. This emoji can symbolically represent the modern person's desire to escape the noise of the world or to no longer engage with a particular topic.
