Dynamic range is the ability of the ear to deal with quick shifts in sound loudness. Suddenly everyday noises sound unbearably or painfully loud. The disorder is often chronic and usually accompanied by tinnitus, but can occur in patients who have little or no measurable hearing loss.
Hyperacusis differs from recruitment, which is an abnormal growth in the perception of loudness accompanied by hearing loss. With recruitment, loud noises are uncomfortable. With hyperacusis, all sounds are too loud. Most patients also experience inner ear pain or a feeling of fullness (pressure) in the ears. Hyperacusis can be devastating to the patient’s career, relationships, and peace of mind. Finding the proper diagnosis is difficult because few doctors understand hyperacusis.
Diagnosis may be made by:
- Audio Exam:
- This allows the physician to depict one's ability to hear sounds at different frequencies.
- Medical History:
- A physician will determine whether any other conditions or events affect your hearing.
- Physical Exam:
- A physician will examine the ear and head.
