The Journal of the Acoustical Society of America, 1940
The theory of King for the radiation pressure exerted by plane progressive waves on spheres has been used to compute the constants for spheres of radii (r) of the order of a wave-length (λ) of the sound in the medium. These are given for integer values of α = 2πr/λ from 1 to 11, and for α = 15 and 20.

Methods for estimating the sound pressure at the eardrum
The Journal of the Acoustical Society of America, 1999The problem of estimating the sound pressure generated at individual eardrums is systematically investigated. In audiometry, the reference to the pressure at the eardrum is usually realized by using a coupler such as the IEC 711 ear simulator, which is intended to approximate an average ear.

Intracardiac sound and pressure events in man
The American Journal of Medicine, 1967Abstract Described herein are intracardiac sound and pressure events recorded in 105 patients with organic heart disease by means of an intracardiac micromanometer at right heart catheterization. Sound-pressure relationships are defined in patients with selected congenital and acquired cardiac diseases.

Journal of Geophysical Research, 1971
Recently several workers have developed theories to explain the characteristics of the pressure wave associated with thunder. Few et al. [1967] presented approximate calculations for a cylindrical shock wave. Jones et al. [1968] have extended the strong-shock solution into the acoustic region.

Mechanical Pressure-Gradient-to-Pressure Sound Transducer
The Journal of the Acoustical Society of America, 1961In places of high ambient-noise level, the use of electrical devices as an aid to speech communication is sometimes precluded by safety requirements. A mechanical device may then be used provided that the individuals concerned are close to each other.

Loudness, Sound Pressure, and Subglottal Pressure in Speech
The Journal of the Acoustical Society of America, 1963Three experiments using one speaker and 30 listeners provided correlated data on subglottal pressure, average volume velocity through the glottis, fundamental frequency, effective sound pressure in front of the speaker, and judgments of loudness. Experiment 1: In 12 repetitions each of bee, bay, bar, bore, and boo spoken at various loudnesses, it was ...

Note on the relationship of sound pressure and sound intensity
Applied Acoustics, 1986Abstract It is usual to calculate the sound pressure at a given location by energy addition of all relevant components. Another approach considers the sound power per unit area. This note shows that the two approaches lead to different results for ideal line or planar sources.

Loud Speaker Sound Pressure Measurements
The Journal of the Acoustical Society of America, 1930Methods of taking frequency-response curves of loud speakers have tended to become prematurely standardized within commercial organizations, and inadequately standardized in the industry as a whole. Characteristics taken by different experimenters are not comparable.

On Sound Radiation in Terms of Pressure Independent of the Sound Speed
The Journal of the Acoustical Society of America, 1963The surface integrals of the solution to the homogeneous wave equation are discussed with special reference to the use of the pressure independent of the sound speed and point multipole representation for small surfaces enclosing the source. It is shown how the multipole representation can be used for not small surfaces, so as to afford simplification ...
