摘要： A system for dampening sound produced by an air blower such as that used to inflate an inflatable movie screen or other inflatable structures. The system can include an air blower and a muffler. The muffler is configured to reduce or dampen sound output from the air blower and includes one or more surfaces that enclose at least a portion of the blower. An opening may be formed in the muffler to facilitate air flow into the air blower. The blower can include a fan and the opening may allow air to pass through into a space in the interior of the muffler and to the fan, so that it can be output to the inflatable movie screen. The muffler may also include a second opening. The second opening can facilitate output of the air by the blower and to the inflatable movie screen.
