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), AudioCardio 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?

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

How do I use the calibration feature?

  1. Connect your headphones.
  2. Go to a completely quiet place.
  3. One at a time, adjust each of the five sliders to the barely audible level for one of your ears.
  4. One at a time, adjust all five sliders to the barely audible level for your other ear.

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!

When do I need to recalibrate?

  1. While Threshold Sound Conditioning™ is activated, you should hear a faint sound. When that sound is no 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!)
  2. Whenever you change your headphones or earbuds.
  3. Whenever you change your device (tablet or phone).

What do 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 do the graphs show?

1. Hearing Condition
2. Usage
3. 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 to use with headphones or earbuds?

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

Which headphones or 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 Iisten 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 calibration and Threshold Sound Conditioning™ (TSC).
