Speech-in-Noise Training Works!

December 21, 2012 In the News

Song et al (2012) investigated biological mechanisms associated with listening-in-noise using a control (no-training) and experimental (training) group. Auditory brainstem response (ABR) was recorded to speech sounds presented in quiet and noise. Subjects included 60 adults ages 19 to 35 years, approximately two-thirds were female. Training was accomplished via the listening and communication enhancement (LACE) protocol (Sweetow and Sabes, 2006). The QuickSIN (Killion et al 2004) and HINT (Nilsson, 1994) were among the tools used to evaluate perceptual abilities.

The authors concluded that "naturalistic training" that combines sensory and cognitive elements can enhance the central nervous system’s ability to encode acoustic cues, based on their empirical findings. Song et al report "…LACE training generalizes to standardized clinically utilized measures of speech-in-noise perception—a critical factor if (auditory) training is to have an impact on real-world listening."
