Read our Heart Failure research guide →Researchers at Noah Labs want to see if your voice can tell them about fluid buildup in your lungs—a common problem in heart failure. You already have an implanted sensor that measures your heart's pressure. This study asks you to record short voice samples every day for 12 weeks using a mobile app, while continuing your normal heart failure care and pressure monitoring. The researchers will analyze your voice recordings later to see if voice changes match what your sensor shows.
Current pressure sensors are expensive and require surgery to implant. Researchers believe that fluid retention in heart failure may subtly change how your voice sounds, and if they can detect those changes, it could offer patients a simple, non-invasive way to monitor their condition at home in the future.

You would use the Noah Labs mobile app to record your voice every day for 12 weeks. Each recording takes just a few minutes—you'll sustain some vowel sounds and read a short standardized passage. Your pressure sensor readings continue as normal through your regular care. No extra clinic visits are needed, and researchers won't use your voice data to guide treatment decisions during the study—they'll analyze everything after you're done to see if voice changes match pressure changes.
