Each little red circle and blue cross represents the degree of hearing sensitivity for that ear at that pitch. Pitches get higher as you move from left to right. This person has a handicapping hearing loss, slightly more severe in the right than the left, with the greatest loss at 2K (2,000Hz), that pitch which is most important for understanding speech. Hearing aids will be of great benefit.
