Investigating the Effect of Caffeine Consumption on Speech Understanding in Noise in Young Adults

What this Trial Is About

Researchers are investigating how caffeine consumption affects the ability to understand speech in noisy environments among young adults aged 18 to 30. This study focuses on the relationship between caffeine and speech-in-noise comprehension, a skill influenced by both auditory and cognitive functions such as selective attention and executive functions. The goal is to add to existing knowledge since previous studies have not explored caffeine's effect on this specific ability. Participants will be randomly assigned to one of two groups: one group will consume about 280 grams of coffee containing 300 mg of caffeine, while the other group will drink decaffeinated coffee as a placebo. Thirty minutes after consumption, the Turkish Matrix Test will be used to assess speech understanding in noise. Additionally, participants will keep a caffeine diary for one week to track daily intake and complete the Caffeine Use Disorder Scale to classify them as low or high caffeine consumers. During the study, participants will undergo hearing assessments to ensure no hearing loss, and they will be monitored for neurological and psychological history, smoking status, and ototoxic drug use. The primary outcome measured is performance on the Turkish Matrix Test before and after coffee consumption, while the secondary outcome involves scores on the Caffeine Use Disorder Scale. This study is expected to last from April 2025 through April 2026, with all procedures conducted under randomized conditions.
