In linguistics, noise is any interference, barrier, or disturbance that distorts, alters, or prevents the correct transmission and reception of a message between sender and receiver. In a way, we can say that noise is an alteration of the communication channel, so that the message cannot reach correctly from the sender to the receiver. A door in the middle of two rooms is noise. Lack of phone coverage when we are in Son Macià is noise. A parallel conversation at a table of people dining that sounds louder than your own is noise. Cataracts in the eyes that make it difficult for us to read a message on a screen could even be considered noise.
