摘要： Disclosed herein is a sound absorbing system used for an electronic device that has enhanced noise reduction capabilities, while maintaining the cooling performance of the device and without increasing the size of the device.A disk array 1 has multiple fans 3 installed on each of the right and left sides of its front section. A frame 4 that houses a sound absorbing system is placed in the middle of an airflow path through which air passes from the fans 3. Two sound absorbers 5 are arranged inside the frame 4 such that each of the sound absorbers 5 faces the right-side or left-side fans 3. Airflow paths 7 through which air passes from the fans 3 are located in the space between the two sound absorbers 5. The airflow paths 7 are partitioned by an acoustic board 6 such that each of the airflow paths 7 does not have parallel side faces. The frame 4, the sound absorbers 5, the acoustic board 6, and the airflow paths 7 constitute the sound absorbing system. The sound absorbers 5 and the acoustic board 6 are made of sound absorbing materials such as glass wool, urethane foam, and the like. The sound absorbers 5 and the acoustic board 6 are arranged such that they prevent the fans 3 from being seen from the outside of the sound absorbing system.
