The topic of my presentation is the relationship between particular somatic experiences, caused by auditory perception, and a certain semiotic order created by these experiences, when they occur in an extreme situation, become repetitive and are suddenly retrieved from memory. My goal is to examine this relationship in Zofia Posmysz’s works, especially in her novel “Wakacje nad Adriatykiem”. I read it as a study of a forced hyperactivity of the subject of auditory perception, who reconstructs a story about the past based on unexpected sound stimuli heard again, but in completely different circumstances.I will analyze the relationship between listening, emotions, memory and trauma of the novel’s narrator, who in her youth became an “ear witness” of a concentration camp reality. Her story is a testimony to the extent to which the compulsion to decipher all kinds of acoustic phenomena can affect a human functioning in the world. Giving priority to the sense of hearing at the expense of the other senses is here associated with hyperacusis as one of the post-traumatic stress disorders.These experiences, which Posmysz described in her artistic language, are currently explored, for example, by Carolyn Birdsall in her studies on sound memories of the Nazi period, by Steve Goodman who analyzes them in the context of the relationship between sound and emotions, especially fear, or by J. Martin Daughtry who examines them as a process of decoding sounds as tactical signs, serving during a war as a source of information that can save lives.
