This study investigates how age affects the processing of consonants and sentences, focusing on trial structure influenced by auditory cues. Participants were subjected to a 1.0 kHz tone, followed by two independent noise bursts presented through loudspeakers. Consonant-vowel-consonants (CVCs) were concurrently delivered at random intervals with adjustable noise amplitudes to ensure optimal masking for different consonants. Findings contribute to understanding auditory processing mechanisms across different age groups, with implications for rehabilitation approaches.

Figure 3. Trial structure. Trials were cued by 1.0 kHz tone. After 1.0 s, twoindependent 1,200 ms noise bursts were presented through leftand right loudspeakers. Consonant-vowel-consonants (CVCs)were presented simultaneously through both loudspeakers atrandom intervals after noise burst onset. Noise amplitudes were linearly adjusted over 100 ms interval during midvowel segmentof CVC to provide appropriate masking levels for different leading and coda consonants.
