Building Acoustics - an overview | ScienceDirect Topics
Building acoustics is an important characteristic in the design, operation, and construction of building as they have a significant impact on health, well-being, and satisfaction. Therefore a suitable sound insulation is essential for clean and healthy living.
Building Acoustics and Noise Control - ScienceDirect
2020年1月30日 · Building acoustics is an important issue as it is related to indoor environmental quality and human comfort. People's perceptions of acoustic comfort and satisfaction are influenced by the acoustical environment. Sound sources inevitably exist in our environment and application of new knowledge on noise control in buildings is of importance.
Recent advances in building acoustics: An overview of prediction ...
2015年9月1日 · Building acoustics refers particularly to the acoustics issues in buildings, such as room acoustics. To assess the acoustical environment or apply possible noise control measures, it is essential to have appropriate and accurate methods for predicting the level and spectral content of the sound in buildings.
Ten questions concerning Architectural Acoustics - ScienceDirect
2024年11月1日 · Building acoustics [10, 13] deals with isolation against noise from outdoors or from other indoor spaces in the same building, or against noise from building equipment. An evolution has been documented in both fields over the centuries, from the design and construction of ancient theaters to more complex modern buildings.
Noise control study in building acoustics with flexible-absorbent …
2024年12月1日 · In building acoustics, attenuating noise is a challenge, especially to manufacture the exhaust purpose or installation of the HVAC system, where the space area is limited and the length of the duct in these exhaust systems cannot be extended.
Numerical estimation of coupling loss factors in building acoustics
2013年10月14日 · The input powers are usually known, for a given excitation. In building acoustics, the internal loss factor can be computed with analytical expressions available in the literature [16] for most types of subsystems. However, the analytical expression for the coupling loss factor is only available for simple connections.
Practical aspects of MLS measurements in building acoustics
1997年11月1日 · Equations (7) and (8) are valid for monofrequent signals only. In building acoustics the bandwidth of the mea- sured acoustic quantities is usually reduced for evaluation by octave band filters or one-third octave filters. These narrow band signals behave approximately like harmonic signals if short periods of time are considered.
Development of a subjective scale for sound quality assessments …
2020年5月1日 · In building acoustics, it is necessary to conduct both objective and subjective evaluations in a holistic sound quality assessment. However, there is a huge variety in a selection of psychological tools. This arouses the concern about reliability and validity of the tools.
Acoustic metamaterials for sound absorption and insulation in …
2024年3月1日 · When it comes to building acoustics, the frequency distribution of the sound source keeps fluctuating depending upon the noise. Similar to traditional materials, the frequency band for peak performance for passive acoustic metamaterials are determined during their fabrication and assembly.
Animal-based waste for building acoustic applications: A review
2024年5月1日 · Acoustic building materials made from animal waste belong to the category of passive acoustic strategies, which can be applied to contribute to sound absorption and/or sound insulation. Sound absorption is frequency dependent and is intrinsically associated with the thickness, density, and airflow resistance of the material [ 40 , 41 ].
