The objectives of this study were to compare the speech patterns of normal hearing and hard-of-hearing children in order to further describe the relationship of these two groups; to survey the literature to determine group comparisons already established; to provide statements which would further clarify the relationship; and to report these statements for use in the field of speech and hearing pathology. A total of one hundred thirty-four subjects were used in the study. An audio gram and speech analysis were secured on each subject. Subjects were then divided into five groups: Normal hearing; slight hard-of-hearing; moderate hard-of-hearing; educationally deaf; and profoundly deaf. Sound graphs were formed which revealed the percentage of subjects in each group having a given sound defective. These sound graphs were grouped according to site of placement and manner of formation
