Background: The aim of this study was to compare noise sensitivity (NS) in schizophrenic individuals with/without hallucinations and healthy individuals. Procedure: A retrospective (causal–comparative) study was conducted in three groups: (i) A group of individuals with schizophrenia and auditory hallucinations (14 participants), (ii) a group of schizophrenic individuals without auditory hallucinations (14 participants) selected by purposive sampling and (iii) a control group (19 participants) selected by convenience sampling. Schutte’s Noise Sensitivity Questionnaire was used to measure NS. Analysis of Variance and Kruskal–Wallis tests were applied to compare the three groups. All the analyses were done using SPSS-20. Results: ANOVA results indicated that the groups were significantly different in terms of NS (p<0.001) and that NS was higher in groups whose participants were schizophrenic (119.64 and 102.36, respectively, in groups with or without auditory hallucinations) compared to that in the group with healthy individuals (94.79). Conclusions: On the basis of this study, it became evident that patients with schizophrenia are more sensitive to noise than healthy individuals. The results also indicated that schizophrenic patients with auditory hallucinations are more sensitive to noise than those without auditory hallucinations.
