weighted noise मीनिंग इन हिंदी

उदाहरण वाक्य

1. Weighted noise power in dB is referred to 1.0 picowatt.
2. Using a noise signal which is inherently random requires considerable weighted noise signals in the time domain presents many challenges.
3. In Europe, the A-weighted noise level is used for instance for normalizing the noise of tires on cars.
4. While the NRR and the SNR ( Single Number Rating ) are designed to be used with A-weighted noise levels, which have lower frequencies de-emphasized.
5. The National Institute for Occupational Safety and Health recommended and the U . S . EPA mandated that 7-dB compensation between C and A weighting be applied when the NRR is used with A-weighted noise levels.
6. An integrating meter simply integrates or in other words'sums' the frequency-weighted noise to give sound exposure and the metric used is pressure squared times time, often Pa��s, but Pa��h is also used.
7. A-weighted noise measurements were found to give misleading results because they did not give sufficient prominence to the 6 kHz region where the noise reduction was having greatest effect, and sometimes one piece of equipment would even measure worse than another and yet sound better, because of differing spectral content.
8. A-weighted noise measurements were found to give misleading results because they did not give sufficient prominence to the 6 kHz region where the noise reduction was having greatest effect, and did not sufficiently attenuate noise around 10 kHz and above ( a particular example is with the 19 kHz pilot tone on FM radio systems which, though usually inaudible is not sufficiently attenuated by A-weighting, so that sometimes one piece of equipment would even measure worse than another and yet sound better, because of differing spectral content.
