Sound radiation and sound insulation performances of maritime bulkheads

, 2019
The research of materials matching low weight and high resistance has always been a key factor in the shipbuilding industry to increase performances and loading capacity. Nowadays, other issues add up to economical convenience, and building quiet ships is important not only for passengers and cabin crew, but also to make harbor areas more comfortable ...

Study of double windows efficiency in order to improve sound insulation in buildings

, 2016
The aim of this research is to evaluate sound insulation behavior of double windows, when windows, when a second window is placed upon a previous one, keeping an air layer between them.

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

Advanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Comparison of Sound Insulation Performance of Water Drop and Trapezoidal Sound Barriers

International Journal of Advances in Engineering and Pure Sciences
With increasing urbanization and industrialization, noise pollution has become a significant environmental issue. This study compares the sound insulation performance of two different sound barrier designs: water drop and trapezoidal. COMSOL Multiphysics software for computational simulations is used to calculate sound transmission loss (STL).
