The invention discloses a tire noise testing device, and relates to the technical field of tire noise testing. The device includes a vehicle-body part, a hauling part, a load, a noise elimination hood and a noise detection device; the hauling part is connected with the vehicle-body part, and the load is installed on the vehicle-body part; the vehicle-body part is provided with a mounting position for mounting a tire, and the noise elimination hood is connected to the vehicle-body part and covers the mounting position, so that the tire on the mounting position is placed in the noise elimination hood; the noise detection device for detecting tire noise is installed in the noise elimination hood. The technical problem is solved that a rotary drum method and a coast-down method are high in testing cost, the noise elimination hood can isolate environment noise during the testing, test data is more accurate, and the testing accuracy is improved. The invention further provides a tire noise data acquisition system. T
