This study will be used to compare the effects of two auditory stimulation methods on improving vital signs parameters, reducing the severity of chest pain, and improving the sleep quality of cardiac patients.

This study aims to To evaluate the relative efficacy of two auditory stimulation techniques in enhancing cardiac patients' vital sign assessments.

• This study aims to examine two auditory stimulations for their ability to alleviate chest pain in patients with heart conditions.
• The goal of this study is to evaluate two audio stimulations for their potential to help heart patients have a better night's rest.

This research made use of two different therapies including audio stimulation. Group A used familiar auditory stimulus, which was a spoken message, and group B used sounds of nature.
