The purpose of this study was to test Rogers' principle of integrality by asking: Does a varied harmonic auditory environment increase the perceived restfulness of patients, who are hospitalised in order to heal following surgery? This study modified a previous study (Smith, 1986) which showed that varied harmonic sound had a more positive effect on the perceived restfulness of healthy subjects than did quiet ambience. This experimental study tested 22 post-operative inpatients, using a non-equivalent control group design with pretest and posttest. Varied harmonic sound was provided by audiotaped sequences of music and narrative; quiet ambience was achieved by maintaining quiet within a non-soundproof hospital room. Smith's Restedness Tiredness Scale was used to measure perceived restfulness. The hypothesis was supported at 0.05 level of significance using Analysis of Covariance. The findings imply that nursing actions can manipulate environmental sound in order to promote restfulness in surgical inpatients.
