Adding moderate background noise eliminates the deficit children with ADHD symptoms have in recognizing speech in quiet environments.

49 secondary school boys participated in the study.
Forty-nine secondary school boys between 9 and 10 years of age ( M = 10,2) participated in the study.
15 participants were included in the final ADHD symptom group.
Thus in all 15 participants were included in the ADHD symptom group and the remaining 31 participants constituted the typically developed control group.
Key findings
In quiet conditions, children with ADHD symptoms needed speech to be 2 dB louder than controls to recognize it. However, in the 65 dB noise condition, this difference disappeared completely. Both groups performed in parity in the noise condition.
Methodology
Researchers tested 49 boys aged 9 to 10 years. They compared 15 children with ADHD symptoms against 31 typically developed controls on a speech recognition task. This task was completed in absolute quiet and in 65 dB of auditory noise.
Limitations
Because the sample only included 15 boys in the ADHD symptom group, these results must be treated as preliminary. The findings cannot be generalized to girls since no girls were included. Additionally, because the study was conducted in a school setting rather than a soundproof room, ambient noise may have affected the quiet threshold measurements.
