Book excerpt: "Introduction: Current newborn hearing screening include testing with otoacoustic emission and automated auditory brainstem response. Unfortunately, both tests are affected by the presence of material in the ear canal and middle ear such as vernix, meconium and amniotic fluid. The primary objective of this study was to perform wideband measurements and otoscopy on newborns in order to determine whether occlusion of the ear canal affects the wideband measurements. A secondary objective was to compare the wideband measurements obtained after birth to those taken at 14 to 28 days later. A third objective was to obtain additional wideband normative data in newborns. Materials and Methods: Newborns from a well-baby nursery were enrolled. Wideband measurements under both ambient and pressurized conditions and otoscopy were done immediately after the hearing screening and between 14 and 28 days later. Occlusion of the ear canal as seen on otoscopy was described on a scale of 0 to 100% in increments of 10.Results: A total of 156 babies were enrolled. On the first measurement, a statistically significant difference in reflectance was found between 0-70% and 80-100% occlusion groups and between 6 groups of frequencies between 250 Hz and 8 kHz. There was no significant difference in reflectance between the right and the left ears. A comparison of reflectance under pressurised conditions between the first and second measurements has shown a higher reflectance at the negative pressure region during the first few days of life. Conclusion: Significant increase in reflectance occurs when 70% to 80% of the ear-canal diameter is occluded. A trend of higher reflectance appears to be present when the canal is pressurized to negative values. A comparison of reflectance between the present study and previous studies is given." --

Available in PDF, EPUB and Kindle. Book excerpt: "Early detection of hearing loss accompanied by appropriate early intervention is important in order to avoid problems associated with delayed language development, with its impact on daily communication, educational achievement, psychosocial development and later employment opportunities. Current screening methods are associated with high false-positive rates, which can be attributed to transient conditions in the external ear and middle ear in the first 48 hours post partum. Tympanometry (input acoustic admittance measurement in the presence of a range of static pressures) is a promising tool for evaluating the status of the middle ear in newborns.Tympanometry involves both non-linear responses and viscoelastic (time-dependent) effects, and the tympanic membrane contributes to the overall response more than other middle-ear components do. We have therefore developed a non-linear viscoelastic model based on experimental data reported in the literature for excised strips of tympanic membrane. The constitutive equation of this model is a convolution integral, composed of the Ogden hyperelastic model and the exponential time-dependent function of the Prony series. The model was validated by reproducing the measured hysteresis effect with a single set of parameters. The newborn ear is anatomically very different from the adult one, resulting in a different input admittance than in adults. We have developed a finite-element model to investigate the admittance responses of the ear canal and middle ear in newborns for frequencies up to 2 kHz. The model was validated by comparison with two sets of clinical data and provides quantitative insight into the separate contributions of the outer and middle ear. The results suggest that admittance measurements could provide more information about the condition of the middle-ear if made at multiple frequencies around its resonance (around 1.8 kHz).Wideband stimuli are used to extend admittance measurements to higher frequencies. Taking into account the fluid-structure interaction (FSI) between the air inside the canal and middle-ear cavity and the structure of the ear, we have extended the frequency range of our newborn model up to 10 kHz. The first and second standing-wave modes in the canal were observed at 7.2 and 9.6 kHz, respectively, and the resonance of the middle-ear cavity was identified at 6.1 kHz. The model was validated by comparison with two sets of clinical data and provides interpretations for features that exist in the clinical data but whose significance was not clear.Our numerical models of the non-linear viscoelastic tympanic membrane and of the admittance responses of the newborn ear provide quantitative insight into the mechanics of the ear and establish a groundwork for the clinical application and interpretation of admittance measurements in newborns." --
