Impulse noise: Some definitions, physical acoustics and other considerations
The Journal of the Acoustical Society of America, 1991An overview of the impulse noise (blast wave) stimulus is presented with an emphasis on examining those parameters that have been traditionally used to quantify the stimulus for the purpose of understanding its effects on hearing.

Physical Characteristics of Gunfire Impulse Noise and its Attenuation by Hearing Protectors
International Journal of Audiology, 1995The peak sound pressure level (SPL), spreading of pressure wave and other physical characteristics of the impulse noise from weapons were studied in actual shooting conditions for assessment of gunfire noise exposure. Additionally, the attenuation of SPL by hearing protectors was measured with miniature microphones to evaluate protection efficiency in ...

Dissociation and Physical Abuse as Predictors of Bulimic Symptomatology and Impulse Dysregulation
Eating Disorders, 1993Abstract The current study examined the relationship between physical abuse, dissociation, bulimic symptomatology, and impulse dysregulation. Subjects were 126 female and 57 male undergraduate and graduate psychology students. Child physical abuse, as measured by the Violence History Questionnaire, was reported by 32% of the sample, The results of this

IEEE Transactions on Dielectrics and Electrical Insulation, 2016
The introduction of the test voltage function or k-factor in IEC 60060-1 Ed. 3 has been an important step to ensure reproducibility and traceability in high voltage tests techniques for lightning impulses with superposed oscillations and overshoots. The standard recommends computed fitting methods to extract a base curve from the oscillating recorded ...

Arm strength and impulse generation: Initiation of wheelchair movement by the physically disabled
Ergonomics, 1986The initiation of wheelchair movement is a function of starting technique, upper extremity strength and the stabilizing potential of the trunk musculature. This study examined the relation between arm strength, activity level, degree of disability and the maximum impulse generated from a resting position while seated in a wheelchair.

Thermal Effects in a Physically Nonlinear Cylinder under Impulsive Loading
International Applied Mechanics, 2005A coupled dynamic problem of thermomechanics is formulated based on a thermodynamically consistent modification of the Bodner-Partom model. This formulation is used to analyze the thermomechanical state of an aluminum cylinder under axial impulsive loading. The problem is solved by the finite-element method.

A simplified physical model for amplitude distribution of impulsive noise
IEEE Transactions on Communication Technology, 1964Analytic representations for the a,mplitude distribution of impulsive noise have generally been presented as numerical approximations to experimental data. While this provides a satisfactory solution to design problems, it is of some interest to consider a simplified physical model of the impulsive noise sources affecting narrow-band receivers, and to ...
