Temporal processing, spectral processing, and speech perception in noise abilities among individuals with chronic kidney disease undergoing hemodialysis

The Effect of Hemodialysis on Spectral and Temporal Processing Abilities and Speech Perception in Noise among Individuals with Chronic Kidney Disease

“…The spectral processing and speech perception in noise abilities were evaluated by measuring spectral ripple discrimination threshold (SRDT) and speech recognition threshold in noise. The procedure used to measure GDT, amplitude-modulation detection threshold, SRDT, and speech recognition threshold in noise was same as described in earlier investigations [Nambi et al, 2016;Kumar et al, 2020Kumar et al, , 2021.…”

“…The rippled noise was generated as described by [Won et al, 2007]. Procedure used to generate stimuli and measure the SRDT in the present study was similar to our earlier investigations [Nambi et al, 2016;Kumar et al, 2020Kumar et al, , 2021. Spectral ripple noise was used as the stimuli for measuring SRDT.…”

“…The duration of spectral ripple noise was 500 ms. The procedure used to measure the SRDT was similar to an earlier investigation [Kumar et al, 2021]. A two-alternative forced-choice task with a two-down, one-up adaptive procedure was used to estimate the SRDT.…”

“…The procedure used in the present study for measuring the GDT is described in an earlier investigation [Kumar et al, 2021]. The GDT was measured for gaps in white noise.…”

“…D' Andrea et al [2013] reported poorer performance among half of the individuals with CKD on staggered spondaic word test [D'Andrea et al, 2013]. Few studies have reported poorer auditory processing and speech perception in noise among individuals with CKD [Kumar et al, 2021;Jain et al, 2022]. However, none of the studies have investigated the effect of hemodialysis on speech perception and auditory processing abilities.…”
