What this trial studies

This study investigates how caffeine consumption affects young adults' ability to understand speech in noisy settings. It aims to explore the relationship between caffeine intake and cognitive functions related to auditory processing, particularly focusing on selective attention and executive functions. Participants will be divided into experimental and placebo groups to assess the impact of caffeine on their speech comprehension in noise. The study seeks to fill a gap in existing literature regarding the cognitive effects of caffeine on auditory functions.

Who should consider this trial

Good fit: Ideal candidates for this study are young adults with normal hearing who do not have a history of neurological or psychological disorders.

Not a fit: Patients with hearing loss, neurological or psychological disorders, smokers, or those using ototoxic drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of how caffeine may improve speech comprehension in challenging auditory environments.

How similar studies have performed: While studies have shown caffeine's effects on cognitive functions, this specific investigation into its impact on speech understanding in noise is novel and untested.
