Between-group comparisons involving the three possible pairings of the groups revealed a pattern of results to suggest that: (a) compared to the control group, both treatment groups (i.e., VA and VH) experienced significantly more improvement on specific outcomes measures and (b) there were no significant differences between the VA and VH groups to indicate superiority of one treatment over another. Results, however, from a posttreatment questionnaire regarding the perceived benefits of treatment revealed that, compared to the VH group, the VA group reported more clarity of their speaking and singing voice (p = .061), greater ease of voice production (p = .001), and greater compliance with the treatment program (p = .045). These findings clearly support the clinical utility of voice amplification as an alternative for the treatment of voice problems in teachers.

    Expansion is commonly used to reduce microphone noise and low-level environmental noises that can be annoying to hearing aid users. It may also improve or reduce the perception of low-level speech. This study assessed the impact of two expansion algorithms, single and multiple channel, on speech...
