Free Auditory and Focus Baseline Check
A short check to establish an initial baseline for auditory perception, focus state, and short-term memory. Results are for self-observation only and are not medical diagnosis.
Environment and Volume Check Before You Start
- Please take this check in a quiet space. Headphones are recommended.
- Set your phone or computer volume to around 30%, then use the check tone below to fine-tune it.
- The volume should be clear, comfortable, and not sharp or irritating.
- After the check begins, please do not change your system volume. This may affect your baseline result.
The full check takes about 3–5 minutes. Results will first appear on this page. You can decide whether to save your result and apply for a public-interest training code.
Find Your Detectable Boundary
Start from a clearly audible volume, then slowly lower it. When you become unsure whether you can still hear the sound, confirm the threshold.
Left Ear｜500 Hz
Please keep your environment quiet and do not change your phone or computer system volume.
Faster Spoken Digit Memory
The system will read numbers at a pace close to daily work conversation. If the first answer is incorrect, the same sequence will be played once more.
Play the numbers when you are ready
Please listen first, then enter the numbers. There is no need to rush.
Which Sound Is Higher?
You will hear two tones. Please choose the one that sounds higher or sharper.
Play the test tones first
Please wait until both tones finish before answering.
Initial Baseline Result
These results are intended for personal state observation. If you join the 7-day public-interest training, the same code can be used to compare changes before and after the experience.

Would you like to track changes after 7 days of structured listening?
If you would like to join the public-interest training follow-up, you can choose to save your result and apply for a training code. Daily feedback and the Day 7 follow-up check will use this code to compare before-and-after changes.
Your Training Code Has Been Created
Please copy and save this code, then paste it on the membership application page. Daily feedback and the Day 7 follow-up check will use it to compare your data.
How to Read the Data
Left / Right Ear Volume Threshold
A lower value usually means you can perceive the sound at a lower output level. This is not medical-grade dB HL and is only suitable for personal before-and-after tracking.
Auditory Working Memory
This reflects short-term information buffering and can be affected by fatigue, stress, and multitasking.
Pitch Difference Discrimination
A lower JND ratio means you can detect a smaller pitch difference.
Apply for 7-Day Public-Interest Training Tracking
After submission, a public-interest training code will be created. Please copy this code and enter it on the membership application page, so daily feedback and the Day 7 follow-up check can be matched later.
