| Zusammenfassung | Nowadays, newborn hearing screen programmes are used widely for early identification of hearing disorders enabling effectiveness of treatment to be enhanced. However, ear simulators underpinning traceability in such measurements are currently only suitable for adults. One objective of the EMRP EARS Project is to design a universal ear simulator that can be adapted to adults, children and newborns. The purpose of the presented work is to specify the ear simulator requirements. These arises from key physiological parameters relating to ears and hearing gathered from literature, for newborns, children and adults. In fact specifications for five target age groups have been established. The need for a universal occluded ear simulator for the calibration of insert earphones and probes has also been identified. This confirms expectations of hearing specialists consulted by means of a questionnaire. The specifications include geometric details of the ear canal for each age group. The basis of the proposed design for the artificial ear canal is to use a duct of geometry close to the real ear geometry in order to reproduce the transfer acoustic impedance of the ear canal as accurately and simply as possible. Details of this are discussed. Further study will deals with designing additional components to match the input impedance of the ear canal. |
