Non-linear Identification Applied to Broadband Turbomachinery Noise
Coherence based source analysis techniques can be used to identify the contribution of broadband noise sources in the exhaust of a gas turbine and hence enable the design of noise reduction devices. However, when the broadband noise source propagates in a non-linear fashion the identified contribution using ordinary coherence methods will be inaccurate. In this paper, an analysis technique to e...
متن کاملAeroacoustics research in Europe : The CEAS - ASC report on 2008 highlights
aeroacoustics community on an European scale and European aeronautics activities internationally. In this context, ‘‘aeroacoustics’’ encompasses all aerospace acoustics and related areas. Each year the committee highlights some of the research and development projects in Europe. This paper is a report on highlights of aeroacoustics research in Europe in 2008, compiled from information provided ...
متن کاملA Broadband Low-Noise-Amplifier
This report describes the design of a two-stage broadband low-noise-amplifier (LNA) for the frequency range from 3 GHz to 9 GHz, using GaAs MESFETs with an ft of 20 GHz. The passive components were implemented with microstrips. In the frequency band of operation, the achieved noise figure (NF) is within 0.5 dB from the minimum NF of a single transistor, the power gain is 15 dB, flat within 1 dB...
متن کاملInfants' sensitivity to broadband noise.
Infants have higher pure-tone thresholds than adults. One explanation is that infants do not adopt the frequency-selective listening strategy that adults use when detecting tones. In contrast to other models of infants' immature sensitivity, the listening strategy account predicts that infants will be more sensitive to broadband sounds, relative to adults. Infants 7-9 months old were tested in ...
