The aim of this paper is to study the soundscape of the Cyclops’ Island as it is built by the poet in the ninth song of the Odyssey (v. 166-506). I propose to list all descriptions or sound actions of this excerpt and to try to understand which soundscape they are forming. I will also examine their relationship with other types of descriptions - visual or sensory - in order to show how they strongly participate in the general picture painted by the poet. I will concentrate particularly on the sounds and cries of the Cyclops and especially on the term φθόγγος. In parallel, I will study some specific terms used in the acoustic description of the blinding of Polyphemus to emphasize the importance of expressive vocalisms and to show that the use of one or another term is never insignificant. Finally, this will give food for thought about the uses and especially the meanings of these different expressive terms in the Homeric poetry. φθόγγος, ὀρυμαγδός, ῥοῖζος, σίζω, οἰμώζω.
