Utilizing wide dynamic range compression most likely will - Answer ✔ Increase speech
perception at low input levels
Wide dynamic range compression makes soft sounds audible and loud sounds
comfortable by: - Answer ✔ Widening the range of input intensity levels while allowing
output to be between the auditory threshold and loudness discomfort level of the user
