To reduce traffic noise in urban environments, pass-by noise measurements must meet strict regulations for vehicle noise certification. As of December 29, 2018, homologation and conformity by indoor ...

Of the vehicles we've measured so far using this methodology, the Genesis Electrified GV70 is the quietest at a 70-mph cruise, measuring 64 decibels and 18 sones. Comparatively, a Honda CR-V Sport ...

Electrical noise, like taxes, is always with us. Most of the time noise is small and we can ignore it, but there are some measurement circumstances where noise must be dealt with. What can be done to ...

Researchers at the National Institute of Standards and Technology (NIST) and industry collaborators have developed improved methods for accurately measuring very faint thermal "noise"--caused by ...

For decades, carmakers treated cabin noise as a single number problem, something to be tamed with thicker glass and extra ...

Engineers are not just adding more insulation, they are reinventing how interior noise is captured, modeled, and judged so ...

The European Union Aviation Safety Agency (EASA) published guidelines to establish the noise levels of drones below 600 kg, the first proposal worldwide for this, applicable to a wide variety of drone ...

The European Union Aviation Safety Agency (EASA) is pleased to announce the release of its guidelines to establish the noise levels of drones below 600 kg, which aim at providing harmonized procedures ...

With today's applications requiring lower and lower noise-figure amplifiers, noise-source uncertainty becomes a bigger and bigger concern. Microwave modeling software ...
