Acoustic specialists have developed a computer model which allows them to calculate noise levels along the entire Swiss rail network. The program describes how much sound is radiated and how it is ...

Real-world signals, such as vibration, temperature, pressure, and light, require accurate signal conditioning and signal conversion before further data processing in the digital domain. In order to ...

This article describes the composite current source (CCS) noise modelfor cell-level noise analysis. CCSisa modeling capability in the open-source Liberty cell modeling standardthat encompasses timing, ...

Input-referred calculations are a valuable tool to understand the expected performance of a measurement system, helping to optimize designs and inform system specifications. Why input-referred ...

Transportation noise, largely from road, railway and aircraft traffic, is one of the most widespread sources of environmental stress and discomfort in daily life. Health effects of noise may emerge ...

A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

A first-of-its-kind computer can perform calculations using the random “noise” that is inherent in our world. It is built using standard commercial components and could eventually run artificial ...

In a bid to reduce the impact of aircraft noise on local communities, Stockholm Bromma airport is on the verge of erecting a transparent perimeter wall that will minimise the sound of its operations, ...
