Frequency spectra of cochlear acoustic emissions (’’Kemp‐echoes’’)

Journal of the Acoustical Society of America, 1981
Cochlear acoustic emissions were recorded with a sensitive microphone from within the ear canal of normal hearing subjects. Frequency spectra of these acoustic emissions were obtained with two different procedures: real-time recording or calculation of the spectrum of time-averaged emissions.

Waveform and Frequency Spectra of Acoustic Emissions

The Journal of the Acoustical Society of America, 1971
Stress waves generated internally by deforming materials provide information about the operative deformation mechanisms. These stress waves are known as acoustic emissions. Acoustic emission stands alongside conventional ultrasonic methods as a useful technique of nondestructive testing.

Acoustical Phonon Spectra of Biological Polymers

Nature, 1966
ALTHOUGH much has been done in an attempt to understand the kinetics of biological processes in terms of their molecular motions1–4, it appears that until now no one has attempted to calculate or measure the proper (normal) modes of motion of helical biological polymers.

Acoustic cavitation noise spectra

Applied Scientific Research, 1982
Experiments are described which allow to measure and visualize the dynamics of the total acoustic cavitation noise spectrum. A distinct threshold for broad-band noise much higher than the threshold for the first subharmonic has been found. At this noise threshold a broadening of all spectral lines is observed.
