A Soundscape Healing Environment: An Exploratory Study of the Relationship Between Therapeutic Sound Frequency and Outcomes for Clinical Care Settings

ABSTRACT The catalyst for this research was rooted in a patient satisfaction survey reported the need for an ambient quiet setting. This study used a descriptive comparative design augmented with qualitative data. The sample consisted of 54 participants came from one of three primary care clinics listened to 22 minutes of existing natural clinical sounds while the others listened to therapeutic sound hertz in a treatment room. The survey data correlated identify if an association existed or not to add therapeutic soundscape hertz back into a clinical ambient setting could affect the patient experience and wellness. Rather than, continue with abatement program efforts to remove unwanted sounds or mask the noise. Quantitative data were collected on mood states and biometric measures consisted of respiratory, heart, pulse systolic, and diastolic blood pressure rates. Qualitative data 5-Point Likert scale and open-ended questions determined participants' awareness of ambient sounds within the clinical setting. Data from participants were analyzed and compared separately for each clinic. The metrics were found to be statistically correlated (p<0.05) for the POMS-A survey and biometric measures using a Chi-square test. After the intervention, two clinics reported a 60%, and the third clinic an 80% mood state changes. Clinic 2-M reported the greatest significant mood state change. The t-Test validation biometric measures showed no significant evidence among the test and control groups for Clinic 1-L (396, 417, 444 Hz). Clinics 2-M (528, 639 Hz) and Clinic 3-H (714, 852 Hz) did share significant evidence to respiratory, heart, and systolic blood pressure rates. The respondents revealed 27% had a positive opinion of the therapeutic sound hertz perceived as silent or quiet, 59% had a negative opinion of unwanted sounds included communication as disruptive, and 16% felt the clinic’s physical design was poor. As a whole, this study indicates exposing patients to therapeutic sound hertz had a positive impact on their biopsychosocial wellness states. The value and novelty of this study show by adding selective distinct therapeutic sound hertz levels back into the clinic setting have profound implications for future researchers to build upon how the quality soundscape performance effects on the patient.
