“…Therefore, filling the horizontal and vertical joints of the blocks that compose the masonry wall is essential to guarantee an adequate soundproofing. This improves the airtightness of the system and can be reinforced by the use of plaster in both sides of the walls which fills the reminiscent voids and increase their surface mass and stiffness (FRINGUELLINO; SMITH, 1999; FERREIRA NETO; BERTOLI, 2010; MAEKAWA; RINDEL; LORD, 2011;RINDEL, 2018).…”

The materials that compose a construction system influence directly the acoustic performance of buildings.In masonry systems, through experiments, the geometry of the blocks and the types of coating were perceived as fundamental factors on the acoustic performance of walls. Therefore, this study intends to enrich the database and promote analysis for the civil construction industry by evaluating the airborne sound reduction of masonry walls composed by ceramic blocks with and without mortar coating. Accordingly, different partitions made of different ceramic blocks were built to determine the performance discrepancies in the partitions’ behavior due to physical characteristics and the influence of the mortar coating. These analyses were made in laboratory. As a result, without coating, the highest sound reduction was observed in the samples with more bulk mass and higher Aliq/At ratio (relationship between the net and gross areas of the ceramic blocks). Then, with the mortar coating, the coating improved the sound reduction. Moreover, the bulk mass was the most influential characteristic in comparison to the Aliq/At ratio, even though the best results were obtained in the samples with higher Aliq/At ratios.

“…According to the classification of Hopkins (Hopkins 2014) and Rindel (Rindel 2018), the shapes of walking surfaces that can float on base slabs were divided into three main types, as shown in Figure 1. For the first type, labeled "A", the walking surface and base are connected via resilient materials at individual points.…”

“…In previous theoretical studies, experiments were performed to verify the accuracy of the estimated insulation performance of floating floors (Mak and Wang 2015). Floating floors can be categorized into three types based on the connection state between the walking surface and the base slab (Hopkins 2014;Rindel 2018). For floor types in which the walking surface covers the entire base via resilient layers, the insulation performance is considerably influenced by the mass of the walking surface and the dynamic stiffness of the resilient material (Gerretsen 1999;Schiavi, Belli, and Russo 2005;e Sousa and Gibbs 2014;Schiavi et al 2007;e Sousa and Gibbs 2011).…”

With an increasing demand for quieter residential environments, impact sound insulation for floating floors is gaining importance. However, existing methods for estimating the performance of heavy impact sound insulation are limited by their inability to comprehensively analyze various types of floating floors, as well as difficulties mathematically determining the input force of the reference source for heavy impacts. To overcome these limitations, this study proposes empirical models for estimating the sound insulation performance of floating floors under heavy impacts. The proposed models are then validated; the model with the highest accuracy exhibits an average estimation error of 2.73 dB at 50-630 Hz. The proposed models exhibit better accuracies than existing analytical models for frequencies below 100 Hz, where the estimation errors of the analytical models were large. Thus, the proposed models may help reduce errors in analytical estimates or when estimating a single numerical quantity for sound insulation rating during the design stage of multifamily housing.

“…É de especial interesse em edifícios residenciais, mas também em escritórios, hospitais e edifícios escolares. O isolamento acústico em edifícios está sob pesquisa e padronização desde os anos 50 (RINDEL, 2018). No Brasil, os requisitos de desempenho normalizados se aplicam apenas para edificações habitacionais como já mencionado anteriormente, enquanto que em diversos países há uma exigência mínima para as demais tipologias construtivas.…”

O pensamento a respeito do desempenho acústico nas edificações é consideravelmente novo no âmbito da construção civil especialmente no Brasil, onde, os requisitos de desempenho normalizados se aplicam apenas para edificações habitacionais através do conjunto de normas da ABNT NBR 15575:2013, também conhecida como norma de desempenho, enquanto que em diversos países há uma exigência mínima especifica para outras tipologias. Neste artigo, são apresentados alguns estudos de caso em edificações escolares, onde são demonstradas pesquisas realizadas tanto com medições em campo como avaliações qualitativas. Vale destacar que o processo de ensino aprendizagem necessita da escuta e compreensão da fala em todo o ambiente, possibilitando a boa interlocução entre professor e alunos. O objetivo deste artigo é avaliar o isolamento ao ruído aéreo de uma sala de aula tipo de uma instituição de ensino de nível superior. Tendo como objeto de estudo uma sala de aula de campus universitário localizado no estado do RS que possui 114,24 m2. A investigação da pesquisa foi através de verificação em campo do isolamento ao ruído aéreo, com ensaios conforme procedimentos da ISO 16283-1 para os ensaios de sistemas de vedações verticais internos e da ISO 16283-3 para os ensaios nos sistemas externos (fachadas). Os resultados apresentam desempenho abaixo do previsto quando comparados a referências internacionais específicas para ambiente escolar e, ainda, se considerados os requisitos estabelecidos na NBR 15575-4 o sistema construtivo também não atenderia o nível mínimo de desempenho.
