Preclinical acoustic efficiency evaluation of bionic ear

چکیده

Objective. To study the major acoustic properties of prototype bionic ear developed in order to confirm its functional performance.
 Materials and methods. Acoustic were measured using Random Phase MultiSine signal a test bench, which simulated implant-emitter-osseous tissue-inner system. The resulting pulse response was converted target characteristics: FR group lag. Experiments carried out for -6dB level, 10 times each methods used.
 Results. Microtia is congenital auricular hypoplasia or aplasia (anotia) often involves impairment total loss hearing. One way rehabilitate this type patients use bone-conducting apparatuses (bone anchored hearing aids), allow compensate component but not restore facial aesthetics. This paper deals with we have previously developed, performance clinical use. Our analysis characteristics system showed frequency uniform enough extended voice range (100 10000 Hz). experimental research demonstrated that operating time battery depletion h 26 min 25 % amplification, 05 50 9 48 75 amplification.
 Thus, vibratory emitter determined, confirmed artificial eligible testing.
 Conclusions. Major measured, preclinical studies successful testing.

Micromechanical resonator array for an implantable bionic ear.

In this paper we report on a multi-resonant transducer that may be used to replace a traditional speech processor in cochlear implant applications. The transducer, made from an array of micro-machined polymer resonators, is capable of passively splitting sound into its frequency sub-bands without the need for analog-to-digital conversion and subsequent digital processing. Since all bands are me...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
