The invention concerns the use of riluzole or one of its pharmaceutically acceptable salts for preventing andor treating acoustic traumas and, in particular, different types of deafness and tinnitus. The first switch is connected with the optical encoder, the second switch with the optical encoder and the first switch, the signal integration amplifier with the first and second switches, the first separator with the signal integration amplifier and the signal processor, and the second separator with the signal processor. The plurality of panels comprises at least one side panel. A classification module is then coupled to the characterization module to dynamically assign each of the user requests an allowable processing deadline based on the corresponding user tolerance threshold of that user request. A member supporting the first and second steps may form a storage compartment.
