Outcome Measures

Primary Outcomes (2)

  • Correctly identified abnormal heart and lung sounds by doctors using two stethoscopes: NoaScope and 3M™️ Littmann®️ Classic III.

    Each patient will receive two auscultation examinations: one with NoaScope and another with 3M™️ Littmann®️ Classic III. The investigators will determine the clinical feasibility and non-inferiority of NoaScope to the FDA-approved 3M™️ Littmann®️ Classic III from auscultation findings (heart and lungs) by doctors (holding varied levels of clinical expertise). Doctors will examine each patient using two stethoscopes: NoaScope and 3M™️ Littmann®️ Classic III. The investigators will also measure inter and intra observer agreement by the Kappa index with the help of a questionnaire. Kappa values \< 0.8 means weak to moderate level of agreement and Kappa values between 0.8 - 1.0 would mean strong level of agreement.

    1 month

  • The measurement of sound quality in a clinical setting by means of an MOS scale on a questionnaire.

    The investigators will measure sound quality on a mean opinion score scale with values ranging form 1 (bad) to 5 (excellent).

Secondary Outcomes (1)

  • Difference in performance between subgroups of doctors based on clinical experience.
