Measuring aircraft noise impact in a low signal‐to‐noise environment

Measuring Code Optimization Impact on Voltage Noise

In this paper, we characterize the impact of compiler optimizations on voltage noise. While intuition may suggest that the better processor utilization ensured by optimizing compilers results in a small amount of voltage variation, our measurements on a Intel R © Core2 Duo processor show the opposite – the majority of SPEC 2006 benchmarks exhibit more voltage droops when aggressively optimized....

On Measuring the Intelligibility of Synthetic Speech in Noise — Do We Need a Realistic Noise Environment?

Assessing the intelligibility of synthetic speech is important in creating synthetic voices to be used in real life applications, especially for the ones involving interfering noise. This raises the question how to measure the intelligibility of synthetic speech to correctly simulate such conditions. Conventionally, this has been done using a simple listening test setup where diotic speech and ...

The relative impact of aircraft noise and number in a full-factorial laboratory design

The discussion on the extension of existing airports and the construction of new ones has reached a new peak. This paper reviews the literature on the possibility of trading noise for number of aircraft operations in the context of increasing air travel. Moreover, two new laboratory studies are presented, which model two ways of immission reduction: (1) fading out old and loud aircraft at exist...

A new method for aircraft noise synthesis

This paper presents a method to synthesize aircraft noise. The method provides designers with a tool for sound quality evaluation with which target sounds for future aircraft design can be developed. Quick and economic evaluations concerning the quality of sounds of different design alternatives or improvements on existing aircraft become possible. The method has the potential to become a cruci...
