Energy method to calculate the density of liquids using ultrasonic reflection techniques
(2001-12-01)
In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...

Sparse arrays and image compounding techniques for non-destructive testing using guided acoustic waves
(2013-06-01)
Piezoelectric array transducers applications are becoming usual in the ultrasonic non-destructive testing area. However, the number of elements can increase the system complexity, due to the necessity of multichannel ...

Application of acoustic models for polydisperse emulsion characterization using ultrasonic spectroscopy in the long wavelength regime
(Elsevier B.V., 2020-10-05)
Ultrasonic spectroscopy is a technique that often has been used for measuring the particle size distribution in suspensions and emulsions. The ability to analyze concentrated heterogeneous systems and optically opaque ...
Cochlear microphonic responses to acoustic clicks in guinea pig and their relation with microphonic responses to pure tones
(1983)
Cochlear microphonic (CM) responses to acoustic transient stimuli were studied at the three more basal turns of the cochlea in the guinea pig. The responses to rarefaction and condensation pressure pulses of less than ...
Influence of nonlinear effects on the acoustic levitation of small spheres
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the nonlinear characterization of a single-axis acoustic levitator and the analysis of the influence of nonlinear effects on the acoustic levitation of small spheres. First, the nonlinear characterization ...
