The goal of this observational study is to learn whether the HALD investigational device can accurately record heart, and lung sounds during a routine cardiology clinic visit.

The main question aims to answer:

Can the HALD device capture heart and lung sounds in different positions and during deep breaths, and do these recordings match the sounds assessed by the investigator during a physical exam?

Participants will have a clinical assessment performed by the investigator as per clinic standard of care. After which, the HALD device vest will be applied to the chest of the participant , and heart and lung sounds will be recorded in a series of positions. The recordings will be transferred automatically to a computer and will later be listened to and assessed for accuracy.

The information collected will be used for research purposes to help understand how the device vest may be used in the future.

This study is looking at how well the HALD device can record heart and lung sounds during a routine cardiology clinic visit. All participants will have a required clinic exam and ECG performed. Participants who qualify and agree to participate will put on a T-shirt and wear the HALD vest while heart and lung sounds are recorded in several positions, including lying down and sitting, with normal and deep breaths. The recorded sounds will later be compared to what the investigator heard during the exam to check for validity and accuracy. All recordings are saved securely and will be used to help researchers understand how the device could support heart and lung assessments in the future.
