Karolina Smeds

Karolina Smeds has an MSc in Engineering Physics from KTH, Stockholm, Sweden, and an MSc in Audiology from the University of Southampton, Great Britain. She has been working as an engineer at the Manilla School for deaf children in Stockholm and has been lecturing at the Audiology program at Karolinska Institutet in Stockholm. At the audiology program she has been responsible for technically oriented courses such as physics, signals and systems, psychoacoustics, hearing aid technology and hearing aid fitting.

Karolina Smeds carried out her PhD work at KTH under the supervision of professor Arne Leijon and in 2004 she got her PhD with the thesis, “Less is more? Loudness aspects of prescriptive methods for nonlinear hearing aids”. Prescriptive methods were evaluated for hearing-impaired people with mild to moderate hearing loss. The main result was that generic prescriptive methods available today generally prescribe higher gain than members of this group of hearing-aid wearers prefer. A summary of the thesis can be found here.

In 2006, when Widex decided to establish the new ORCA Europe research group, Karolina Smeds was asked to be the director.

Frederic Marmel

Frederic Marmel has a PhD in Cognitive Sciences from the University of Lyon (France), which he completed in 2008 under the supervision of Dr. Barbara Tillmann, and which investigated the auditory processing of musical structures. Between 2009 and 2018, Frederic completed a series of postdoctoral research projects in hearing science and audiology, focusing mostly on temporal processing abilities and mechanisms in normal-hearing and hearing-impaired listeners, as well as on cochlear synaptopathy.

Frederic then joined the European RUMBLE project that aimed to develop regulations and norms for the low-level sonic booms of the future generation of supersonic aircrafts. This was the opportunity for him to take auditory research methods out of the lab and focus on listeners’ experience in realistic auditory environments.

Frederic joined the ORCA Europe research group in September 2021 as a Research Engineer.
