The complete measuring system shall comply with the IEC requirements, be it a sound level meter or a larger system including DAT-recorders or PC-based analysers. The electric background noise level in the measuring set-up shall be at least 10 dB lower than the acoustic background noise ...
A method for reducing impulsive noise in electromagnetic geophysical data utilizes a receiving antenna and one or more noise sensors. The type of noise sensor used depends on the type of impulsive noise which is to be monitored. Motion noise is monitored with a tilt meter or similar motion ...
This paper describes techniques for real-time threshold-based detection and filtering of broadband and narrowband RFI for the correlator and beamformer chains of a telescope back-end, with specific applications to the upgraded Giant Meterwave Radio Telescope (uGMRT). The Median Absolute Deviation (...
A source location has been determined with the use of polarization analysis, assuming that the main axis of the polarization ellipse is to be perpendicular to the direction towards a source (the goniometer method). The orientation of polarization ellipse, that is the angle θ that the principle...
PURPOSE:To improve the effect of noise reduction, by providing a variable resistance element being conductive/nonconductive by a DC voltage in response to an input electric field level and changing the sensitivity of a adjusting circuit of sensitivity to noise by means of the conduction/non...
Matthew Branch tested common rifle and pistol calibers with and without muzzle suppression, using strict military/industrial standard sound measurements for impulse noise. The study used a Br眉el & Kj?r 2209 sound level meter with a B&K 4136 microphone, and a B&K 4220 pistonphone for ...
The measurement of impulsive sound is made generally either by means of a soundlevel meter or by oscilloscope observations.In order to avoid the disadvantages peculiar to these methods we have developed an apparatus especially designed for impulsive sounds of very short intensity.We have been able ...
Reduction in impulsive noise hearing hazard by earplugs and earmuffs is calculated with an electroacoustic lumped鈥恜arameter model of HPD attenuation using real ear attenuation at threshold (REAT) data. Energy flows into the occluded volume along three paths, each considered as a piston: (1) ...
