Your OIDO hearing aids are perfectly calibrated
The OIDO Hearing Test uses pure-tone audiometry to measure your hearing ability with precision. During the process, the app plays carefully calibrated beeps at different frequencies and volumes in each ear.
Deep, bass-like sounds similar to a bass drum. These tones test your ability to hear lower-pitched sounds and voices.
The range of everyday speech and conversation. These are the sounds most critical for understanding people talking.
Sharp sounds like birds chirping or consonants in speech (S, T, F). Often the first to be affected by hearing loss.
Each tone is played directly through your hearing aids into your ear canal to ensure maximum accuracy.
As each tone plays, you'll be asked a simple question. It's that easy!
If you can't hear a tone, the app automatically increases the volume until you can. This process continues across all frequencies to build your complete hearing profile.
Most hearing loss doesn't affect all sounds equally. You might hear low voices perfectly but struggle with high-pitched speech sounds like "S" or "T" consonants.
Background noise might overpower conversation, especially in restaurants or crowded places. The test identifies exactly which frequencies need help.
Once complete, the app uses your hearing fingerprint to deliver personalized, crystal-clear hearing
Amplifies exactly where your hearing needs help most
Reduces distracting sounds without muffling speech
Ensures natural, comfortable hearing levels
You understand the process, now it's time to find your fit
