P-Value 0.00015 shows that, there is significant change observed in mean score at pre –test and post- test knowledge score is significantly increased post intervention. H0 is rejected and H1 is accepted. Conclusion : A study was undertaken on A study to assess the effectiveness of audio assisted teaching on selected Respiratory problems knowledge among flour mill workers in selected areas of Pune city among so flour mill workers.
