title: The effects of expansion time constants on the objective performance of hearing instrument users.
abstract: The present study investigated the effects of expansion time constants on the objective performance of 20 hearing instrument users fitted binaurally with digital in-the-ear products. Objective performance was evaluated in quiet using the Connected Speech Test and in noise using the Hearing in Noise Test. Results indicated that objective performance in quiet and in noise decreased as the expansion time constant increased. Furthermore, expansion time constants affected the objective performance of listeners with varying degrees of hearing loss in a similar manner.
