Study on Sound Transmission across a Floating Floor in a Residential Building by Using SEA

open access: yesArchives of Acoustics, 2021
For the purpose of reducing the impact noise transmission across floating floors in residential buildings, two main sound transmission paths in the floating floor structure are considered: the stud path and the cavity path. The sound transmission of each

Sound insulation properties of a spherical structure of subwavelength size

open access: yesAIP Advances, 2019
Because of the limited sound insulation provided by a single material, it is common to use multiple layers of materials to improve the effects of sound insulation, but multiple materials increase the size of the model.

Sound insulation at low frequencies [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1972
The transmission of airborne sound between two rooms coupled by a panel is investigated. At low frequencies individual modes in the rooms and the panel control the transmission. It is shown that resonant modes in the room are the chief cause of frequency-dependent variations in low-frequency sound insulation.

SOUND INSULATION OF A MECHANICAL WORKSHOP

open access: yesSafety Engineering, 2014
The paper presents a design process related to sound insulation of a small mechanical workshop for storing eccentric presses, which is located in a densely populated housing estate. Starting from the theoretical model of acoustic insulation power of a single solid partition, a complex partition and a multi-

SETTING UP A PROBLEM OF AIR-BORNE SOUND IN-SULATION CALCULATION FOR DOUBLE LAYER MASSIVE ENCLOSURES ON THE BASE OF THE MODELS WITH THE CONCENTRATED PARAMETERS

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2020
The calculation methods on the base of the concentrated parameters models, which were formed in the XX century, allowed to get simple and theoretically consistent solutions for the problems of one-layered building partitions sound insulation finding. The

Measurement and Calculation of Sound Insulation [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1930
The term “reduction factor” has been given different meanings. Architects, builders and even many acoustical engineers, are not aware of these different meanings, and consequently unnecessary confusion arises whenever insulation data from different laboratories are compared.

Enhanced sound insulation in double wall structures via MAMs: An RBF-based optimisation approach

open access: yesMaterials & Design
Double walls are widely used as they provide a higher level of sound insulation without compromising on mass. However, due to the coupling resonance between the structure and the cavity, additional sound insulation valleys occur, which are not beneficial
