Hearing aids with automatic signal-processing circuitry (ASP) have recently become available commercially. This investigation tested the claims of manufacturers that the ASP hearing aid improves speech recognition in noise. Word recognition scores were obtained from ten hearing-impaired adults using two different hearing aids (ASP and conventional) and four background noise conditions (quiet, +5, 0, and -5 dB signal-to-noise ratios). The results indicated that the more difficult the listening condition, the greater the advantage provided by the ASP instrument. The ASP hearing aid may prove to be beneficial to many hearing-impaired individuals who have difficulty communicating in noisy situations.
带有自动信号处理电路（ASP）的助听器最近已在市场上销售。这项研究对制造商声称的ASP助听器能改善噪声环境下语音识别能力的说法进行了测试。使用两种不同的助听器（ASP和传统型）以及四种背景噪声条件（安静、信噪比为+5、0和 -5分贝），从十名听力受损的成年人那里获得了单词识别分数。结果表明，听力条件越困难，ASP仪器所提供的优势就越大。ASP助听器可能对许多在嘈杂环境中交流有困难的听力受损者有益。
