The Project

The Workshops

In contrast to the generally accepted normal frequency range of hearing, non‐audible sound outside of this range has gained only moderate attention, attention despite the proliferation of sources and growing number of complaints in recent years. The now widespread practice of screening the hearing ability of neonates and children has highlighted the lack of sufficient metrological underpinning and no recognized ear simulator is available on the market for infants. These two separate, but important questions have been addressed within the project “Metrology for a universal ear simulator and the perception of non non‐audible audible sound” (EARS) which is carried out within the framework of the European Metrology Research Programme (EMRP). Two international workshops will be held in early 2015 to disseminate results of the project work to stakeholders in industry and society, and drive further innovation and research within the European community.

The workshops will give the opportunity to share the final results of the project and to discuss all related issues of the topics In round‐table topics. round table discussions, discussions new concepts shall be discussed and possible future collaborations initiated. Keynote speakers from scientific research and industry will highlight various aspects of each topic. Furthermore there will be the possibility for attendees to present a poster or a 5‐minute talk. (Please state upon registration.)

Prototype ear simulators for neonatal hearing assessment, assessment designed against a specification derived from clinical and anatomical data. These prototypes are the first in a new family of ear simulators that will cover all target age groups, and feature universal concepts for both design and application.

One goal of the project is a better understanding of the relation between perception of sound and the underlying sensory processes. This was investigated by psychophysical study alongside brain response measurement by magnetoencephalography and functional magnetic resonance imaging.

Workshop on universal ear simulator 26 M h 2015 26 March 2015 NPL, London (UK) This workshop will examine a new range of ear simulators that have been developed specifically for all target age groups, from neonates to adults. It will cover their development, performance and application in hearing assessment. The workshop targets researchers and practitioners in audiology, audiology hearing screening, screening medical physics professionals and healthcare policy makers.

Workshop on non‐audible sound 16 ‐ 17 April 2015 PTB, Berlin (Germany) This workshop focuses on the investigation of non‐audible non audible sound and its potential for creating annoyance or presenting even a hazard to hearing. The measurement of brain responses to audible stimuli, the determination of subjective hearing parameters, the measurement of non‐ audible noise and the impact of all these results on definition of exposure limits, regulation, and standardization are key aspects in this workshop. It refers to a wide range g of experts p involved comingg from scientific research institutes, health and safety bodies or regulating authorities. Detailed information on programme and registration will be available in October 2014 on the project website www.ears‐project.eu
