Wind turbine aeroacoustic noise and noise mitigation strategies.

The Journal of the Acoustical Society of America, 2010
Wind turbines are becoming an important piece of the solution to low-carbon power production. However, as more turbines are installed near population centers, the environmental impacts associated with these machines, such as noise, are also becoming more obvious.

Mitigation of substation noise

Electrical Engineering, 1931
NOISE REDUCTION IN SUBSTATIONS has in most cases taken the form of confining the noise within certain reasonable limits rather than eliminating it at its source. In accomplishing this, however, other complications are introduced, especially as regards ventilation.

High frequency atmospheric noise mitigation

Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002
The performance of high frequency (HF) radio communication and radar systems can be limited by noise generated by sources external to the receiving antenna. Below 10 MHz, atmospheric noise generated by worldwide thunderstorm activity tends to be the dominant natural source.

Mitigating wind noise in multichannel active noise control systems

The Journal of the Acoustical Society of America, 2023
Multichannel active noise control (ANC) systems have been investigated to reduce outdoor low-frequency noise, such as power transformer noise and traffic noise. However, in outdoor environments, wind noise is inevitable and significantly degrades the noise reduction performance of active control systems.

Rainfall noise simulation and mitigation

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2022
A newly constructed and otherwise well-regarded building suffered from excessive rain noise in open areas where the roof deck was exposed. A single major rain event was used to characterize the existing condition, making use of a handheld sound level meter, mobile phone recordings, and weather radar data and corresponding rainfall rates.

Noise mitigation systems and low-noise installation technologies

2014
In line with Germany’s national renewable energy targets, thousands of wind turbines are going to be installed in the North Sea and the Baltic Sea in the coming decades. This expansion of offshore wind power is obliged to take place in a sustainable and environmentally sound manner.

Mitigation of structureborne noise nuisance

The Journal of the Acoustical Society of America, 2001
Noise is radiated directly from the vibrating structure as structureborne noise. A structureborne noise case in a domestic building is described in this paper. The pipes were installed and mounted vertically with little or no insulation between the pipes and the walls.

Noise Sources, Radiation and Mitigation

1981
This lecture is concerned with developing a basic understanding of physical mechanisms of underwater acoustic noise: the noise radiated by ships, submarines and torpedoes. It is not possible in one short lecture to cover all of the aspects of these subjects.

Quantum Noise Mitigation in NISQ Devices: Baseline Noise Characterization, Zero-Noise Extrapolation, and Measurement Error Mitigation

This project presents a comprehensive study of quantum noise mitigation applied to a two-qubit Bell-state circuit using Qiskit Aer. The work includes three experiments: 1) baseline depolarizing noise characterization, 2) zero-noise extrapolation (ZNE) to recover ideal fidelity under scalable noise, and 3) measurement error mitigation using ...

Low Cost Noise Barriers for Mitigation of Rail Noise

2018
Noise barriers are a widely used mitigation measure for rail noise, particularly for new rail line developments. Precast concrete barriers are typically used for rail noise mitigation as their high mass allows them to effectively mitigate low frequency noise from sources such as freight locomotives.
