The iHearTest provides a scoring system from 1 to 5 for each ear. It is based on the World Health Organization (WHO) grades of hearing impairment, but the score is based in terms of ability instead of impairment. A Right Ear or Left Ear score of 5 means that you have good hearing ability in that ear*. A score of 1 indicates that you have extensive hearing impairment in that ear and that you should see a hearing professional for further evaluation. A score from 2 to 4 indicates that your hearing may be improved with our invisible, high-performance hearing devices. Below is a chart that shows information you can expect after taking the iHearTest.
