Sound intensity processing by the goldfish

The Journal of the Acoustical Society of America, 1985
Capacities of the goldfish for intensity discrimination were studied using classical respiratory conditioning and a staircase psychophysical procedure. Physiological studies on single saccular (auditory) nerve fibers under similar stimulus conditions helped characterize the dimensions of neural activity used in intensity discrimination.

Sound intensity and sound reduction index

Applied Acoustics, 1993
Abstract The sound intensity technique has been tested on sound insulation measurements under laboratory conditions. A detailed measurement and evaluation procedure is proposed. About 30 different measurements have been carried out in three different laboratories to estimate the precision of this intensity method when compared with the traditional ...

Measurement of sound intensity

Journal of Sound and Vibration, 1977
A method is formulated for sound intensity measurement in a non-dispersive medium. It is shown that two microhpones are necessary for obtaining the components of the intensity vector at a given point. In addition, errors associated with measurements are discussed.

Measuring Sound Intensity

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">We are basically interested in Sound Intensity whenever we deal with sources of sound in noise control. The development of techniques and new tools for the direct measurement of the flow of acoustic energy offer new ways for determination of source location, source ranking, energy flow path and absorption ...

Mechatronic sound intensity 2D probe

2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR), 2017
The paper addresses the problem of measurement of an acoustic intensity vector in the acoustic field using a singlechannel mechatronic measurement system. However, in any case, the new probe is not capable of replacing the traditional p-p noise probe, though in many cases it is a cost-effective solution with acceptable metrological quality.

Relation of intensity of cardiac sounds to age

The American Journal of Cardiology, 1985
The absolute intensity of the first (S1), third (S3), and fourth (S4) heart sounds (in mm Hg) and the relative intensity of S4 compared with S1 were measured in 146 normal persons, aged 8 to 91 years, using an infinite time-constant, calibrated pressure mechanocardiograph applied to the chest wall with a loading pressure of 400 mm Hg.
