📚Publication Top Notes
1. Sound Localization with Hearables in Transparency Mode
📅 2025-04-25 | Audiology Research
📌 DOI: 10.3390/audiolres15030048
👥 Authors: Sebastián A. Ausili, Nathan Erthal, Christopher Bennett, Hillary A. Snapp
Summary:
This study explores how hearable devices (like earbuds) in transparency mode affect sound localization abilities. The researchers conducted psychophysical experiments demonstrating that while transparency mode helps situational awareness, it can still degrade spatial hearing performance compared to unaided hearing. Implications for hearing aid and hearable design are discussed.
2. Development of a Set of Psychometrically Equivalent Words to Obtain the Speech Recognition Threshold in Rioplatense Spanish
📅 2024 | Federación Argentina de Sociedades de Otorrinolaringología
👥 Authors: Cristiani H, Piegari A, Alonso S, Virgallito O, Sebastián Ausili
Summary:
The team developed and validated a new word list tailored for Rioplatense Spanish to measure Speech Recognition Threshold (SRT). The study ensures psychometric balance, addressing a gap in Spanish-language audiological tools and improving accuracy in regional audiometric diagnostics.
3. A Model Framework for Simulating Spatial Hearing of Bilateral Cochlear Implant Users
📅 2023 | Acta Acustica
📌 DOI: 10.1051/aacus/2023036
👥 Authors: Hongmei Hu, Sebastián A. Ausili, Ben Williges, Jonas Klug, Rebecca C. Felsheim, Deborah Vickers, Mathias Dietz
Summary:
This article presents a computational model that simulates how bilateral cochlear implant users perceive spatial sound. It incorporates head-related transfer functions and neural processing assumptions to predict performance and assess implant strategies.
4. Contralateral Routing of Signal Disrupts Monaural Sound Localization
📅 2023-08-03 | Audiology Research
📌 DOI: 10.3390/audiolres13040051
👥 Authors: Sebastián A. Ausili, Hillary A. Snapp
Summary:
This study investigates the impact of Contralateral Routing of Signal (CROS) hearing aids on monaural sound localization. Results show significant disruption in the ability to localize sounds, emphasizing the need for cautious CROS use in spatially demanding environments.
5. Abordaje clínico de la estimulación facial en implantes cocleares
📅 2023-05-12 | Auditio
📌 DOI: 10.51445/sja.auditio.vol6.2022.0090
