Hearing assessment in infants and children: recommendations beyond neonatal screening.

26 Sep 2009 Congenital or acquired hearing loss in infants and children has been linked with lifelong deficits in speech and language acquisition, poor academic performance, personal-social maladjustments, and emotional difficulties. Identification of hearing ... Read more...

The influence of the coupling of actuation drivers of implantable hearing systems on the mechanics of the middle ear.

30 Aug 2009 We used multifrequency tympanometry to provide middle ear mechanics after implantation of different implantable hearing aids. A total of 34 patients were included in the investigation; 19 of them were fitted with the Otologics system and 15 with the ... Read more...

Aging, hearing acuity, and the attentional costs of effortful listening.

30 Aug 2009 A dual-task interference paradigm was used to investigate the effect of perceptual effort on recall of spoken word lists by young and older adults with good hearing and with mild-to-moderate hearing loss. In addition to poorer recall accuracy, ... Read more...

Technical information about 'Acoustic Impedance Tests'

Definition: Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).
