Abstract: L'invention concerne un procédé de traitement de gain et un dispositif mettant en œuvre ledit procédé, un appareil électronique, et un procédé d'acquisition de signal et un système le mettant en œuvre. Le procédé de traitement de gain consiste : à analyser un signal numérique audio courant pour extraire un indice audio correspondant, et à déterminer un changement d'indice audio entre le signal numérique audio courant et un signal numérique audio associé à la dernière mise à jour d'un paramètre de commande d'augmentation de gain (S101) ; et à déterminer, selon le changement d'indice audio, s'il est nécessaire de mettre à jour un paramètre de commande de gain utilisé lors de l'exécution d'un traitement de gain sur le signal numérique audio courant (S102). Le procédé de traitement de gain peut ajuster, en temps réel, un paramètre de commande de gain pour s'adapter à l'effet de vibrations au niveau de la position d'une source sonore, d'un changement de source sonore (tel que le changement d'un haut-parleur) ou d'un changement du bruit ambiant, ce qui permet d'obtenir une commande de gain favorable.

Abstract: Disclosed are a forward collision transmission structure and an electric vehicle. The forward collision transmission structure comprises a left side collision transmission structure and a right side collision transmission structure. Each of the left side collision transmission structure and the right side collision transmission structure comprises an engine compartment longitudinal beam body and a doorsill inner plate (1), the engine compartment longitudinal beam body comprises an engine compartment longitudinal beam (2) and an engine compartment longitudinal beam rear section (3), and the engine compartment longitudinal beam rear section (3) bends outwards. A tail of the engine compartment longitudinal beam rear section (3) has an overlapping region with the doorsill inner plate (1), and the tail of the engine compartment longitudinal beam rear section (3) and the doorsill inner plate (1) overlap and are fixedly connected in the overlapping region. A longitudinal beam reinforcement plate (4) is provided along the engine compartment longitudinal beam body, and a front beam (5) is provided between the left side collision transmission structure and the right side collision transmission structure. The forward collision transmission structure greatly reduces the space occupied by a vehicle body, such that the usable space when a battery pack is arranged is more foursquare, and the module layout in the battery pack is more flexible, thus improving the capacity of a battery pack of the same size model, and also ensuring the reliability of the frame. In the event of a collision, the safety of the occupant of the vehicle is not threatened due to lack of support caused by elimination of a floor lower longitudinal beam.
