Prevalence of Hearing Loss
• Increases progressively with age
– 40% of people over 60
– 70% of people over 70
– 90% of people over 80

Consequences
• communication difficulty
• social isolation
• frustration
• reduced confidence
• depression
• stress
• risk factor for dementia

Early Symptoms
• Not able to follow voices in a crowd. • Missing key details in announcements made over
public address systems (e.g., at Airport) • Difficulty understanding women’s or children’s
voices • Mixing up “s”, “f”, and other fricatives
– Did you say that you are still waiting for the “buff” or the “bus”?
• Find yourself filling in the gaps. – Cognitive toll …

Impact of on Cognition
![Page 16: Perception of Aging, Cognition, Music: Problems and Prospects](https://reader031.vdocuments.mx/reader031/viewer/2022020911/62020ad7c28aff2aa55a1946/html5/thumbnails/16.jpg)
Shape your environment!
• Choose quiet environments for conversation when possible
• Stand close to the person speaking
• Make sure the speaker is well lit and facing you – We all lip read!
• Ask conversation partners to speak at a moderate pace and loudly but without shouting

Consider hearing aids!
• All hearing aids amplify sound
• Modern digital aids also minimize noise, provide directional sensitivity, and “dynamic tuning”
• OHIP covers diagnostic hearing tests conducted by certified audiologists.
• After receiving hearing aids, most users report an improved quality of life

Other technologies to consider
• Amplified telephones
• Pocket talker
• Personal FM listening systems
