We analyze this approach based on a recent description by its inventors Hamilton, Tapson, Rapson, Jin, and van Schaik, in which they exhibit the \u201cSonar Hopf\u201d model, its analysis and the corresponding hardware in detail. We identify problems in the theoretical formulation of the model and critically examine the claimed coherence between the described model, the measurements from the implemented hardware, and biological data.<\/jats:p>","DOI":"10.3390\/s110605808","type":"journal-article","created":{"date-parts":[[2011,5,31]],"date-time":"2011-05-31T10:04:20Z","timestamp":1306836260000},"page":"5808-5818","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Analysis of the \u201cSonar Hopf\u201d Cochlea"],"prefix":"10.3390","volume":"11","author":[{"given":"Albert","family":"Kern","sequence":"first","affiliation":[{"name":"Institute for Neuroinformatics ETHZ\/UZH, Winterthurerstr. 190, 8057 Z\u00fcrich, Switzerland"}]},{"given":"Stefan","family":"Martignoli","sequence":"additional","affiliation":[{"name":"Institute for Neuroinformatics ETHZ\/UZH, Winterthurerstr. 190, 8057 Z\u00fcrich, Switzerland"}]},{"given":"Wolfgang","family":"Mathis","sequence":"additional","affiliation":[{"name":"Theoretische Elektrotechnik, Leibniz Universit\u00e4t Hannover, Appelstr. 9A, 30167 Hannover, Germany"}]},{"given":"Willi-Hans","family":"Steeb","sequence":"additional","affiliation":[{"name":"Applied Mathematics University of Johannesburg, 2006 Auckland Park, South Africa"}]},{"given":"Ralph Lukas","family":"Stoop","sequence":"additional","affiliation":[{"name":"Institute for Neuroinformatics ETHZ\/UZH, Winterthurerstr. 190, 8057 Z\u00fcrich, Switzerland"}]},{"given":"Ruedi","family":"Stoop","sequence":"additional","affiliation":[{"name":"Institute for Neuroinformatics ETHZ\/UZH, Winterthurerstr. 190, 8057 Z\u00fcrich, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2011,5,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"C300","DOI":"10.21914\/anziamj.v51i0.2543","article-title":"Understanding the mathematics of hearing using electronic circuits","volume":"51","author":"Hamilton","year":"2010","journal-title":"ANZIAM J"},{"key":"ref_2","unstructured":"Andronov, AA, Leontovich, EA, Gordon, II, and Maier, AG (1973).
