Study conducted to evaluate the effectiveness of feedback canceling technology in commercially available hearing aids. Feedback is one of the most distracting problems encountered by people who use hearing aids, as it can be such a huge problem that it often leads to non-use. The invention of digital signal processing can help to minimize feedback without sacrificing gain, audibility, volume, and speech intelligibility. Six behind-the-ear hearing aids, including the Destiny 1200 from Starkey were evaluated in the study. A technological evaluation of the study is presented, while the results are presented in table format. The Destiny 1200 was found to be the most effective in terms of feedback canceling technology on all assessment measures. Implications for future research are discussed.
