Acoustic impedance measurements-correction for probe geometry mismatch.
The effect of evanescent mode generation, due to geometrical mismatch, in acoustic impedance measurements is investigated. The particular geometry considered is that of a impedance probe with an annular flow port and a central microphone, but the techniques are applicable to other geometries. It is found that the imaginary part of the measured impedance error is proportional to frequency, and t...
متن کاملCOMPARATIVE ANALISIS OF SEVERAL ACOUSTIC IMPEDANCE MEASUREMENTS PACS: 43.58.Bh
In this paper we present the experimental data for the acoustic impedance of different materials (typical ground and construction materials) according to different measurement techniques.
متن کاملImpedance-Acoustic Tomography
In this work we present a new hybrid imaging technique that combines electrical impedance tomography (EIT) with acoustic tomography. The novel technique makes use of the fact that the absorbed electrical energy inside the body raises its temperature, thus leading to expansion effects. The expansion then induces an acoustic wave which can be recorded outside the body and consequently be used to ...
متن کاملMeasurement of Eardrum Acoustic Impedance
In this paper we describe a system which we have developed to measure cat ear canal specific acoustic impedance Zsp, magnitude and phase, as a function of frequency, for frequencies between 200 Hz and 33 kHz, and impedance magnitude between 4.0 to 4.0×105 [Rayles] (MKS). The object to be measured is placed at the end of a 3.5 mm diameter sound delivery tube. After a simple calibration procedure...
متن کاملMeasurements of acoustic impedance at the input to the occluded ear canal.
Multi-frequency (multi-component) acoustic impedance measurements may evolve into a sensitive technique for the remote detection of aural pathologies. Such data are also relevant to models used in hearing aid design and could be an asset to the hearing aid prescription and fitting process. This report describes the development and use of a broad-band procedure which acquires impedance data in 2...
