A broadband RF noise generator
IRE Transactions on Electron Devices, 1955A simple broadband noise generator was constructed which produced substantial noise power over the frequency range from 10 mc to 1,000 mc. The measured noise factors were 90 db or better over this range. The noise was generated by an electric arc discharge that operated in a conventional RC relaxation oscillator circuit.

Adjoint-based Broadband Noise Minimization using Stochastic Noise Generation
25th AIAA/CEAS Aeroacoustics Conference, 2019In this paper, we present an adjoint-based broadband noise minimization framework using stochastic noise generation (SNG). The SNG module is implemented in the open-source multi-physics solver suite SU2 and coupled with the existing Reynolds-averaged Navier-Stokes (RANS) to allow fast assessment of broadband noise sources.

Smart Panel Technology for Broadband Noise Reduction
Noise & Vibration Worldwide, 2003The possibility of a broadband noise reduction by piezoelectric smart panels is demonstrated. A smart panel is basically a plate structure on which piezoelectric patches with electrical shunt circuits are mounted and sound absorbing material is bonded on the surface of the structure. Sound absorbing material can absorb the sound transmitted at the mid
