Age-Related Changes in Objective and Subjective Speech Perception in Complex Listening Environments

Area of Science:

• Auditory Perception
• Gerontology
• Speech Science

Background:

• Older adults frequently report communication difficulties in challenging acoustic settings.
• Understanding age-related changes in speech perception is crucial for maintaining quality of life.

Purpose of the Study:

• To review and summarize how speech perception in complex listening situations evolves across the adult lifespan.
• To synthesize findings on age-related auditory changes in demanding acoustic environments.

Main Methods:

• Literature review of age-related changes in speech understanding.
• Summary of laboratory studies investigating speech perception in noise and competing speech.

Main Results:

• High-frequency hearing loss and cognitive function significantly affect speech understanding in older adults.
• Middle-aged adults perform similarly to younger adults with noise maskers but struggle with competing speech.
• Self-perceived hearing difficulties are comparable between middle-aged and older adult participants.

Conclusions:

• Listening in real-world environments is multifactorial, influenced by hearing and cognition.
• Standard audiological assessments may not capture real-world speech understanding challenges.
• Patient self-reported difficulties are vital indicators of communication struggles.
