Piping System Noise Issues: Multiple Noise Sources

ASME 2005 Power Conference, 2005
Noise levels in power plants continue to be exceeded on occasion in spite of recent developments such as industry wide use of the International Electrotechnical Commission (IEC) control valve standard 534-8-3. There are several reasons for this related to the specific piping system under consideration.

Noise-Loop Multiple Access

IEEE Transactions on Vehicular Technology, 2016
A fundamental problem for signal processing in wireless communications is the separation of multiple signals/users from their mixture. The problem is simpler if they are nonoverlapping in either the time domain or the frequency domain. Two signals may be overlapping in both time and frequency, but they can still be easily separated if they are ...

Multiple-edge noise barriers

Applied Acoustics, 1995
A numerical model using boundary element techniques is discussed which enables the insertion loss for various noise barriers of complex profile and surface cover to be calculated. The model is applied to single-foundation noise barriers to which additional side-panels are added to create fork-like profiles.

Noise Sensitivity and Multiple Chemical Sensitivity

Noise & Vibration Worldwide, 2013
Noise sensitivity is a personality trait covering attitudes to noise in general. Multiple chemical sensitivity (MCS) is the most commonly used label for clinical chemical intolerance. This study aimed to investigate if the Weinstein's Noise Sensitivity Scale and Quick Environmental Exposure and Sensitivity Inventory's (QEESI) Chemical Intolerance ...

The Performance Of Multiple Noise Barriers

Journal of Sound and Vibration, 1994
Abstract A numerical model, based on boundary element techniques, was used to solve the acoustic wave equation in two dimensions, in order to study the performance of various configurations of road traffic noise barriers. The mean insertion loss for a broadband road traffic noise source over a range of receiver positions behind the barrier is used as

Noise reduction: multiple solutions

IEE Colloquium on Signals, Systems and Chaos, 1997
It is an interesting property of chaotic systems that, given a knowledge of the underlying dynamics, even a series of quite crude or noisy observations is sufficient to allow the state-space trajectory of the system to be reconstructed to a very high level of accuracy-far higher accuracy than say a simple moving time-average.
