Abstract
Inexperienced and experienced users of hearing aids often report a strong desire for their hearing aids to provide significantly better understanding of speech when communicating in noisy situations. This article will summarize several technologies that have significantly improved the understanding of speech in noise. This article provides a short review of recent research reporting that many of the current hearing aids with digital signal processing (DSP) have not significantly improved the understanding of speech in noise relative to analog signal processing. On the other hand, the findings have shown that DSP is often preferred when compared with hearing aids with analog signal processing. Discrepancies between the objective and subjective findings will be discussed.
