Many children with autism have a difficult time during a fire drill in the school. The purpose of this quasi-experimental research project was to test the hypothesis that Fire Alarm Sound Desensitization Training (FASDT) helps children with autism respond correctly during fire alarm activations. Parents and teachers of children with autism were surveyed for their experiences with children with autism and how they respond to fire alarms. Based on data collected from the surveys and previous research, the most significant concern for children with autism and fire alarms is the loud noise. Many children with autism suffer from a condition known as hyperacusis, which is an abnormal reaction to otherwise normal or soft sounds. A series of three fire drills from 15 preschool and kindergarten classes were video recorded, and student behavior assessments conducted, to determine the effectiveness of the FASDT.Based on teacher surveys and data collected, there appears to be an improvement in behavior of students who participated in the FASDT. Data did not support the null hypothesis that, after receiving FASDT, there will be no difference in the response of a child with an ASD to the sound of a fire alarm and those who have not received the training. The Mountain Brook Fire Department will become more aware of the needs in our schools during fire drills, identify and work to resolve behaviors that pose a threat to students and faculty during fire drills, and encourage implementation of a FASDT program for all kindergarten and preschool students in the Mountain Brook Schools. Further research needs to be conducted to determine if FASDT works for other developmental disabilities, whether refresher type training is necessary to maintain long-term desensitization, and does the desensitization carry over into other arenas such as assemblies or sporting events.
