Presbycusis could be associated to increased risk to fall. There is little about the impact on postural balance of hearing aids. In this study, the investigators describe the postural balance evolution before and after hearing aid fitting in presbycusis-affected adults (55-80years old) consulting Angers University Hospital ENT department and ENT Medical Doctor of Le Mans .

After being informed about te study and consentment, patients meeting inclusion criteria consulting for presbycusis and in indication for hearing aids will be included to have posturometry (V0). Posturometry is performed 3 months later, before the first hearing aid installation (V1a) and after (V1b), as well as three months after hearing aid wearing (V2). Evolution of posturometry parameters without hearing aids between V0 and V1a serve as control and is compared to the evolution of posturometry parameters after hearing aid wearing between V1b and V2.

Inclusion Criteria:

• 55 to 80 years old
• ARHL within PTA superior to 30dBHL, and intelligibility threshold 30dB or worse defining hearing aid fitting indication in France

Non inclusion Criteria:

• hearing aid fitting refusal or contrindication
• vestibulare rehabilitation in past 3 months
• unusual physical activity the day of the posturography test
• incapacity to understand the instruction, or to stand up the time of posturography without help
• predictable incapacity to perform posturography in the time of the study

Exclusion criteria:

• acute affliction that could affect the posturography test
• daily physical activity modification due to medical advice or vestibular rehabilitation between two posturography
