Mild stroke provides a unique opportunity to study the vulnerability of auditory spatial processing within distributed neural networks. We investigated azimuthal sound localization in chronic-phase survivors of mild stroke without hearing aid use using broadband, low-frequency, and high-frequency noise and compared it against a headphone-based lateralization task. Most patients exhibited localization accuracy comparable to healthy listeners. However, 4 of 14 patients showed a striking alteration of auditory spatial perception: instead of a continuous mapping of azimuth, responses clustered into bi- or trimodal (left-center-right) categorical patterns. Comparable deficits were also observed in one of the five age-matched control participants. To our knowledge, such localization patterns have not been reported in listeners without neurological disease. Atypical localization was most pronounced with low-frequency stimuli, suggesting a different role of the respective binaural cues in forming a spatial representation of sound. Differences between loudspeaker-based localization and existing headphone-based lateralization data further suggest that these paradigms engage distinct auditory spatial representations. The findings support the view that auditory space is constructed through higher-order, supramodal spatial mechanisms that are particularly vulnerable to right-hemispheric damage. Overall, the data highlight the challenges of quantifying spatial hearing of stroke survivors both on an individual and on a population level. Challenges include previously undocumented stimulus and method dependencies, an unknown mixing of auditory and neurological factors, and the absence of normative data for a nonstroke control cohort.<\/jats:p>","DOI":"10.1177\/23312165261446384","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T14:40:50Z","timestamp":1778769650000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Localization of Free-Field Sound Sources in the Chronic Phase of Mild Ischemic Stroke"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1830-469X","authenticated-orcid":false,"given":"Mathias","family":"Dietz","sequence":"first","affiliation":[{"name":"University of Oldenburg"},{"name":"Cluster of Excellence \u201cHearing4all\u201d, University of Oldenburg, Oldenburg, Germany"},{"name":"Research Center Neurosensory Science, University of Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Dietze","sequence":"additional","affiliation":[{"name":"University of Oldenburg"},{"name":"Cluster of Excellence \u201cHearing4all\u201d, University of Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8848-5158","authenticated-orcid":false,"given":"Peter","family":"S\u00f6r\u00f6s","sequence":"additional","affiliation":[{"name":"Research Center Neurosensory Science, University of Oldenburg, Oldenburg, Germany"},{"name":"Department of Neurology, School of Medicine and Health Sciences, University of Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karsten","family":"Witt","sequence":"additional","affiliation":[{"name":"Research Center Neurosensory Science, University of Oldenburg, Oldenburg, Germany"},{"name":"Department of Neurology, School of Medicine and Health Sciences, University of Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henri","family":"P\u00f6ntynen","sequence":"additional","affiliation":[{"name":"University of Oldenburg"},{"name":"Cluster of Excellence \u201cHearing4all\u201d, University of Oldenburg, Oldenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,5,14]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1121\/1.422783"},{"key":"e_1_3_3_3_1","volume-title":"Beck depressions-Inventar - FS (BDI-FS): deutsche Bearbeitung","author":"Beck A.
