Hearing Protection Success: Musicians Have a Favorable Response to Hearing Protection and Listeners Are Unable to Identify Music Produced by Musicians Wearing Hearing Protection.

BACKGROUND: Musicians are known to be at risk for developing hearing sensitivity and hearing-related problems given their occupational exposure to high-level sound. Among options for hearing conservation, earplugs are an effective and inexpensive choice. Adoption rates for musicians' earplugs remains consistently low, however, given concerns about the impact of hearing protection on their own performance as well as concerns that the resultant music will be a negative experience for listeners. In fact, few studies have (1) examined musicians' attitudes about using hearing protection while performing themselves and (2) determined whether music played by musicians wearing hearing protection sounds different to listeners. PURPOSE: The purposes of this study were (1) to evaluate how wearing musicians' earplugs affected musicians' perception of their performance while they were playing, and (2) to examine whether listeners can distinguish a difference between music recorded by musicians playing with and without earplugs. RESEARCH DESIGN: Experiment 1: student musicians were recorded playing under two conditions (with and without wearing earplugs) and then were surveyed about their experience. Experiment 2: musically experienced and naïve listeners were presented with musical samples played by musicians with and without earplugs in an ABX format. Listeners responded by indicating whether the third stimulus (X) was conditionally identical to the first (A) or second stimulus (B). RESULTS: Experiment 1: while performing, musicians always preferred the no earplugs condition. The majority, however, rated the overall experience of playing with earplugs as generally positive. Experiment 2: listeners were unable to hear a difference between the two recordings. DISCUSSION: In this experiment, musicians rated their experience playing without hearing protection more favorably than their experience playing with hearing protection, but most musicians rated their experience with hearing protection as generally positive. The inability of listeners to distinguish a difference in music played with and without hearing protection suggests that the listening experience may not be adversely impacted by hearing protection worn by the performers. CONCLUSION: Earplugs are an inexpensive, noninvasive strategy for hearing conservation for musicians, and this study indicates that barriers to wearing hearing protection might be less problematic than previously reported.

Ideologies of aid, practices of power: lessons for Medicaid managed care.

The articles in this special issue teach valuable lessons based on what happened in New Mexico with the shift to Medicaid managed care. By reframing these lessons in broader historical and cultural terms with reference to aid programs, we have the opportunity to learn a great deal more about the relationship between poverty, public policy, and ideology. Medicaid as a state and federal aid program in the United States and economic development programs as foreign aid provide useful analogies specifically because they exhibit a variety of parallel patterns. The increasing concatenation of corporate interests with state and nongovernmental interests in aid programs is ultimately producing a less centralized system of power and responsibility. This process of decentralization, however, is not undermining the sources of power behind aid efforts, although it does make the connections between intent, planning, and outcome less direct. Ultimately, the devolution of power produces many unintended consequences for aid policy. But it also reinforces the perspective that aid and the need for it are nonpolitical issues.
