| Abstract(E) | Blower-induced ventilation noise is a key issue in the development of cooling performance for HEV battery packs. This study develops a prediction method focused on sound attenuation in duct sections (“duct attenuation”). Using the duct system of a production vehicle, the effects of sound-absorbing materials and duct bends on attenuation characteristics were verified. |
