"AudioCardio" is an ear training app that simply listens to sounds.
The app begins with a "Hearing Check." Based on the results, you can train at your preferred frequency, tailored to your hearing characteristics. Improve your hearing by continuing to train while doing other things for 60 minutes a day.

"AudioCardio" is recommended for:

Those who want to try ear training (ear training)

Those who want to try ear training easily

Those who want to make ear training a habit

Those who want to test their hearing

To use the app, you will need listening equipment, such as headphones or earphones.

●Quick Ear Check
Earing conditions vary from person to person, with some people having difficulty hearing conversations or music. Do any of the following apply to you?
■ You set your smartphone, TV, radio, etc. to high volume.
■ You spend a lot of time wearing earphones.
■ You're told you speak too loudly during conversations.
■ You have difficulty hearing high-pitched sounds, such as mosquito noise (high-pitched sounds) or bass sounds (low-pitched sounds).
■ You don't use a listening device with noise-canceling functionality.
■ You don't use earplugs when exposed to loud sounds, etc...
If any of these apply to you, first check your hearing.

● What "AudioCardio" Can Do
■ Easily Check Your Hearing
Listen to sounds of various frequencies and record your perceived loudness. A unique score will visualize your hearing.
■ Provides you with an ear training menu.
Based on your recorded check results, you can select a training frequency. You can also choose your preferred frequency. By using the app, you can improve your attention to sound and awareness of sound changes, and aim to be able to hear a wide range of frequencies at lower volumes.
■ 60 minutes of "listening while doing other things" per day is enough.
To train, simply listen to sounds played by the app that are "just barely audible." The training sounds play in the background, so you can train your hearing while using other apps, watching videos, or listening to music.
We recommend using the app for 60 minutes daily, but it doesn't have to be continuous. Aim to continue using it a little at a time every day.
■ Check your score progress with data
Check results and training history are automatically recorded, allowing you to check your daily score. If you hear a beep during training playback, please check your hearing again or change the frequency menu.
■ Applying scientifically based technology
The technology used in this app was designed with reference to multiple research findings on sound and hearing. We aim to support your daily training by focusing on the new possibilities of sound.
