FAQ

What are the best practices?
  • Connect your headphones or earbuds.
  • Go to a very quiet room to do your calibration.
  • Your device volume should be set between 50% and 60%  and remain set at that exact level during your calibration and during the activation of Threshold Sound Conditioning™.
  • Move the sliders up until you can hear the sounds well, then down until you can barely hear the sound being transmitted. It should be so faint that it’s almost undetectable. Make sure the sliders don’t move when you lift your fingers.
  • Do this for each lever/fader on each ear.
  • Click “TSC”. You may now hear a very faint audible tone.
  • Use Threshold Sound Conditioning™ (TSC) for one hour a day for best results. This is your hearing therapy.
  • Be consistent- Keep your hardware volume the same for both you calibration and therapy.
  • Over time, the faint audible sound will become louder, indicating that your hearing is getting better. When this happens it’s time to recalibrate.
  • We recommend a minimum of 14 days of consistent use and to continue using the app to better protect, maintain and strengthen your hearing.

(Optional) Listen to Music During Therapy

  • You can connect to supported services and/or your on device media to play your favorite music over the audible tone.
  • Adjust the music volume within in the app on the music player screen. Do not the adjust the hardware volume.
  • The feature called Active EQ™ within the music player will adjust the equalizer based on your unique hearing ability. Sounds should be clearer, sharper and warmer without adjusting the volume.

What is Threshold Sound Conditioning™?

Threshold Sound Conditioning™ uses custom (personalized) sound signals to stimulate the inner ear cells at the barely audible level. Threshold Sound Conditioning was clinically tested with conclusive results with Stanford University, Palo Alto Medical Foundation, Samsung Medical Center, Nanjing University and Chung Ang University.

How does Threshold Sound Conditioning™ (TSC) technology work?

By understanding and determining your threshold of sound (sensitivity), Audio Cardio generates a sound signal at the barely audible level that caters to your specific needs. The custom sound signal is played repeatedly to stimulate your inner ear cells, causing the cells to rapidly fire. This exercises your inner ear cells and promotes the creation of new neural pathways to help you potentially increase your hearing ability.

Can I activate Threshold Sound Conditioning™ (TSC) without listening to music?

Yes, Threshold Sound Conditioning™ can be used with or without music. We think of music as water. You can take your vitamins (Threshold Sound Conditioning™) with or without water. It’s based on your preference.

What does the calibration do?

Audio Cardio adjusts your device and measures your threshold of sound to deliver a custom therapy and sound experience.

How do I use the calibration feature?
  • Connect your headphones.
  • Go to a completely quiet place.
  • One at a time, adjust each of the five sliders to the barely audible level for one of your ears.
  • One at a time, adjust all five sliders to the barely audible level for your other ear.
When do I need to recalibrate?
  • While Threshold Sound Conditioning™  is activated, you should hear a faint sound. When that sound is not longer faint, you should recalibrate your settings to your new levels. This is your personal indicator to adjust your calibration back to your barely audible level. (Go you!)
  • Whenever you change your headphones or earbuds.
  • Whenever you change your device (tablet or phone).
What do the sliders on the calibration 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 therapy.

What does Active EQ™ do?

Active EQ™ automatically equalizes the music based on your hearing condition to deliver a completely personalized sound experience. Try listening to your favorite song without Active EQ™, then engage it to HEAR the difference.

How do I turn on Active EQ™ in the music player?

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

What do the graphs show?
  • Hearing Condition
  • Usage
  • Targeted Frequencies
What do the graphs mean?
  • Hearing Condition allows you to track your progress. The full score of 100 indicates great hearing.
  • Usage Time shows the amount of time you have spent using Threshold Sound Conditioning™ (TSC).
  • Most Used identifies the frequencies you targeted during your therapy.
Do I need headphones/earbuds?

Yes, headphone or earbuds are required to calibrate, generate and deliver your custom therapy.

Which headphones/earbuds should I use?

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

What level should I keep the mobile device volume?

The device volume level should be between 50% to 60%. Be sure to keep the hardware volume the same during calibration and therapy.

Ex: If you volume is set to 60% when calibrating, it should also be set to 60% during activation of Threshold Sound Conditioning™.

Can I change the volume while I listen to music?

You should only adjust the volume control within the Audio Cardio app (on the song display screen). Your device (phone/tablet) volume should remain the same for both calibration and Threshold Sound Conditioning™ (TSC).
