“…along with a good acoustic performance if properly designed. These consolidated granular materials are also widely used in numerous outdoor noise control applications such as noise barriers (3,4) and in ground surfaces (5)(6)(7)(8)(9). In this context, the need to reduce CO 2 emissions while limiting traffic noise (10,11) has prompted the civil engineering industry to focus efforts on development of new environmentally friendly granular materials while providing similar sound absorbing characteristics.…”

ABSTRACT:The use of sustainable materials is becoming a common practice for noise abatement in building and civil engineering industries. In this context, many applications have been found for porous concrete made from lightweight aggregates. This work investigates the acoustic properties of porous concrete made from arlite and vermiculite lightweight aggregates. These natural resources can still be regarded as sustainable since they can be recycled and do not generate environmentally hazardous waste. The experimental basis used consists of different type specimens whose acoustic performance is assessed in an impedance tube. Additionally, a simple theoretical model for granular porous media, based on parameters measurable with basic experimental procedures, is adopted to predict the acoustic properties of the prepared mixes. The theoretical predictions compare well with the absorption measurements. Preliminary results show the good absorption capability of these materials, making them a promising alternative to traditional porous concrete solutions. RESUMEN: Propiedades acústicas del hormigón poroso a base de áridos ligeros de arlita y vermiculita.El uso de materiales sostenibles se está convirtiendo en una práctica común para la reducción de ruido en las industrias de la edificación e ingeniería civil. Este trabajo investiga las propiedades acústicas de hormigón poroso fabricado a partir de áridos ligeros de arlita y vermiculita. Estos recursos naturales todavía pueden considerarse sostenibles ya que pueden ser reciclados y no generan residuos peligrosos para el medio ambiente. La base experimental utilizada se compone de especímenes de diferente tipo cuyas prestaciones acústicas se evalúan en un tubo de impedancia. Adicionalmente, se ha adoptado un modelo teórico simple para medios porosos granulares, basado en parámetros medibles con procedimientos experimentales básicos, con objeto de predecir las propiedades acústicas de las mezclas preparadas. Las predicciones teóricas muestran una buena concordancia con las medidas de absorción. Los resultados preliminares demuestran la buena capacidad absorbente de estos materiales, haciendo de ellos una alternativa prometedora a las soluciones de hormigón poroso tradicionales.

“…Previous works have demonstrated that pavement type and vehicle noise signiicantly afect the levels of environmental noise and associated subjective annoyance measurement [40] and detection levels [41]. Vehicle type afects both detection levels and annoyance ratings with a positive correlation between sound intensity, detection rates and annoyance.…”

Road-traic noise is the most signiicant source of environmental noise. Among the several diferent sources of noise emission from vehicles, tyre/road noise at speeds above 40 km/h is the most prevalent. Its negative impact on health is now beter known and may be mitigated by optimising road surface characteristics. Experimental data linking the characteristics of the road surface to levels of annoyance regarding noise remain scarce. Moreover, assessing annoyance by experimental means using real sounds is complex and could impede study interactions with a wide set of variables. In this chapter, we describe, discuss and present the results of a straightforward method to assess tyre/road noise and related annoyance, based on the virtual sounds made by vehicles, with no interferences.

“…Another study on pavement materials compared the noise generated by vehicles crossing cobblestones, dense graded asphalt, and open asphalt rubber pavements (Freitas et al 2012). Comparing the annoyance level, they clarified that the noise, which has been recorded by tire and cobblestone pavement interaction, is the severest compared to the others.…”
