EarClarity™ – Frequency Adjustment
- Human’s hearing frequency range is about 200Hz to 8KHz or so, but with the aging and hearing habit, people will gradually loss high frequency sound.
- 70% of hearing impaired can’t hear the high-frequency sound, while rest of 30% is due to volume is not loud enough.
- MFA (Millisecond Frequency Adjustment) was developed as a hearing solution by UnlimiterHear. In 1.5 millisecond, MFA can detect and analyze High Definition Voice from 20Hz-20,000Hz and identify high frequency consonants then process it in real-time with minimal distortion and maximum clarity.
How MFA Works
Speech limitations over the phone
We were born with the ability to hear up to 20,000Hz. When talking on cell phones, that upper range is reduced to 3,400Hz. There are still important speech information above 3,400Hz that’s why you often have to give context for high frequency sounds like “S for Sam” or “F for Frank” because without the context, the individual high frequency sounds can be imperceptible.
The MFA Solution
MFA precisely identifies all high frequency consonants within 1.5ms (the human ear needs 30ms to detect lag) and brings the audio information above 3,400Hz to within the narrowband spectrum so that previously unclear or inaudible words can now be heard with minimal distortion. Listen to the original sound “Gas” and the MFA processed sound “Gas” and notice that within the full spectrum context, there is almost no distortion.
