What is AudioCardio™?

AudioCardio™ is a mobile app that is designed to protect and strengthen your hearing using our proprietary and inaudible (or barely audible) sound therapy. The AudioCardio™ app allows you to listen to music while you receive your sound therapy.

Why should I use AudioCardio™?

AudioCardio™ promotes better hearing health and practices. Hearing ability peaks before the age of 25 and is often a slow, but steady decline. AudioCardio™ aims to protect and restore your thresholds of sound.

How often should I use AudioCardio™?

Use AudioCardio™ for daily for one hour for optimal results. You can think of it like physical therapy for your hearing. The more consistent you are the better, but some sound therapy is better than none.

What music streaming services can I connect?

AudioCardio™ currently supports Spotify, YouTube, Apple Music and on device media. Other services will be added periodically.

What does the assessment do?

AudioCardio™ adjusts your device and measures your threshold of sound to deliver a custom sound therapy and sound experience.

How do I take the assessment?

  1. Connect your headphones.
  2. Go to a completely quiet room away windows and electronics that give off ambient noise, like refrigerators.
  3. One at a time, adjust each of the frequency sliders up and then down to the point where you can barely hear it.
  4. Do this for each ear (10 total frequencies).

How do I turn on HD Sound in the music player?

Turn on the HD Sound button in the bottom right hand corner of the screen displaying the song. Try listening to the song with and without HD Sound to really HEAR the difference!

When do I need to retake my assessment?

  1. While the sound therapy is activated, you may or may not hear a faint pulsing sound. When the sound becomes more audible, you should retake the assessment. This is your personal indicator to adjust your sound therapy by retaking the assessment and setting it back to your barely audible level.
  2. Whenever you change your headphones or earbuds.
  3. Whenever you change your device (tablet or phone).
  4. At least once per week.

What do sliders on the assessment screen represent?

Each slider represents a range of frequencies. These ranges are key frequencies for speech, communication and music. Move them up and down to the barely audible level to personalize your sound therapy.

What does the hearing score represent?

This score represents great to below average hearing. The higher your score, the better (0-10 scale).

Do I need to use AudioCardio™ with headphones or earbuds?

Yes, headphones or earbuds are required to take the assessment to personalize and receive your sound therapy.

Which headphones or earbuds should I use?

Any set is compatible as long as you use the same headphones/earbuds for your assessment and your sound therapy. Be sure to reassess your settings any time you change your headphones or device (phone/tablet).

Can I change the volume while Iistening to music?

You should only adjust the volume control within the AudioCardio™ app (on the song display screen). Your device (phone/tablet) volume should remain the same for both the assessment and sound therapy.
