Presbyacusis, or age-related hearing loss, is a public health problem, affecting 20% of men and 30% of women over the age of 70 according to the WHO. In the most incapacitating cases, hearing aids are required. Numerous studies have evaluated the benefits of hearing aids, particularly in terms of improved hearing and quality of life.

However, the specific effect of music on language skills has not yet been studied in hearing-impaired older adults.

In this context, it was decided to study the effect of musical priming on the syntactic abilities of adults aged 70 or older with presbyacusis.

This study is based on the hypothesis that music priming with regular music optimizes the syntax language skills of people with presbyacusis, as has already been proven in adults and normal-hearing children.

Inclusion Criteria:

• No objection to participation in the study
• Men and women aged ≥ 70 years
• Patients diagnosed with presbyacusis (age-related bilateral and symmetrical sensorineural hearing loss, all stages combined), with or without the use of a bilateral hearing aid.
• If they use a hearing aid: hearing must have an average free-field fitted tonal threshold of 40 dB max and free-field fitted speech discrimination without lip-reading of 90-100% at 60dB in silence.
• MMSE score ≥ 24/30

Exclusion Criteria:

• Person under legal protection (curatorship, guardianship)
• Person under court order
• Adult unable to provide consent
• Person with a neurocognitive disorder (post-stroke, dyslexia, dyspraxia) or neuro-psychiatric disorder (dementia, autism)
• Severe sensorineural hearing loss with mean free-field threshold > 40 dB and free-field speech discrimination without lip-reading of < 90-100% at 60dB in silence
• Asymmetrical sensorineural hearing loss due to an additional cause of hearing loss on one side.

Secondary exclusion criteria:

Person with syntax disorder (discovery of sentence comprehension or production disorders during syntax test)
