Sound Absorption and Velocity in CO2/D2O Mixtures

Sound Recognition in Mixtures

In this paper, we describe a method for recognizing sound sources in a mixture. While many audio-based content analysis methods focus on detecting or classifying target sounds in a discriminative manner, we approach this as a regression problem, in which we estimate the relative proportions of sound sources in the given mixture. Using certain source separation ideas, we directly estimate these ...

Influence of Aging Temperature on Mechanical Properties and Sound Velocity in Maraging Steel M350

In the present work, the influence of aging temperature on mechanical properties and sound velocity of Maraging steel M350 was investigated. For this purpose, first, samples were solution annealed at 825◦C for 2 hours and then age hardened at 510◦C-600◦C for 3 hours. Hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...

Third sound velocity in thin films of 3He-4He mixtures at low temperature

2014 We present third sound velocity measurements in thin films of 3He-4He mixtures down to 0.1 K. The low temperature behaviour of this velocity suggests the existence of a phase separation perpendicular to the walls even for a film mixture of 3.7 layer thickness. J.

Sound Absorption in the Workplace

The results are in. Recent studies conducted by an independent testing laboratory show that when it comes to acoustics, commercial cushion makes carpet even better. To specifiers and end-users, it will come as no surprise that properly specified carpet cushion reduces noise when used in a commercial installation. What will be of interest is the degree of improvement that has been quantified in ...
