Sentence examples for wall impedance from inspiring English sources

Twelve-hour, three-channel continuous recordings of respiratory rate (chest wall impedance), electrocardiogram (ECG), and hemoglobin O2 saturation (SpO2) were obtained preoperatively and after surgery.

In that model the resistive wall impedance has been considered as the dominating impedance contribution for collimators.

This means that where the two liners are joined there is a wall impedance discontinuity that can cause acoustic scattering.

This paper reports experiments on the active control of enclosed sound fields via wall impedance changes.

Good agreement between prediction and experiment is noted in the former case with predicted wall impedance values, and in the second case with "best fit" empirically derived wall impedance figures.

The wall impedance and the propagation paths of acoustic energy in the presence of the liner may be deduced without any assumption and non-invasively.

Two numerical procedures for finding the acoustic eigenvalues in the rectangular room with arbitrary (uniform) wall impedances are developed.

Further, significant differences in the wall impedances between the articulated vowel and the voice production mode (spoken vs. sung) are detected.

Besides, the three-dimensional rectangular cavity with rigid walls or impedance walls is discussed in the studied model.

It is found that the stall margin improvements vary with the modification of the unsteady shedding flow and the unsteady wall boundary impedance.

Part 1 of this paper presents the experiments performed and a probabilistic algebraic model of the wall acoustic impedance constructed using the experimental data basis for the medium- and high-frequency ranges.
