Birds generate vocalisations (songs and calls) to communicate. Acoustic communication may be hindered by habitat features so birds can use several strategies to favour sound transmission. Sound transmission depends on the acoustic properties of their habitats. Scree slopes, also known as ‘pedrizas’, are frequent in the Mediterranean forests of south and central western Spain. As the acoustic properties of these rocky grounds might favour sound transmission, we propose that birds might actively use ‘pedrizas’ to increase sound transmission. We assessed the following prediction of the hypothesis: the number of vocalisations recorded should be higher near the ‘pedrizas’ than in forest areas far away from ‘pedrizas’. Using portable recorders in the Mediterranean forest of Monfragüe National Park, we found that the number of recorded vocalisations was higher near the ‘pedrizas’. As this result was not due to differences in species richness, we consider it supports the prediction of the hypothesis. This is new evidence that birds might use a natural element within their habitat to increase sound transmission.

A characterization of the sound absorption of a sustainable material with scarce current use such as natural virgin cork is presented in this paper in order to explore further possible applications in the design of acoustic solutions. Different samples of virgin cork not bonded and various decorative panel formats were tested under random sound incidence conditions in a standardized reverberation chamber. The samples in which the outer bark of the cork was facing upwards showed a better behavior as an acoustic absorber, with sound absorption coefficient values generally greater than 0.6 for frequency bands between 1 and 5 kHz. The results obtained were compared with samples of some recycled materials available in the scientific literature, such as sheep wool and PET.

The European Noise Directive proposes using strategic noise maps as tools to assess populations affected by environmental noise. It recommends using computational methods instead of in situ measurements when possible. A sound source’s emission power is an important factor in the calculation of noise indicators. For traffic noise, this parameter is usually defined based on vehicle flow considering an emission spectrum that depends on the type of vehicle and its speed. This study analysed the possibility of using the categorisation method to propose an alternative method of defining a sound source’s emission power to develop noise maps. This was accomplished using previously published values of the emission power per unit length. Another method is also proposed that estimates traffic flows. To verify their estimation capacity, the results of both methods were compared with the values obtained from in situ measurements. The results demonstrated similar uncertainties in both methods and were in the range of expected average uncertainties compared to the results obtained by calculating a noise map with the measured experimental values. In particular, for the differences between calculations and measurements, in absolute values, the mean uncertainties were approximately 2 dBA in estimating different long-term noise indicators. For the differences, the mean of the uncertainties obtained via the categorisation method did not present significant differences for the null value for all the analysed noise indicators. Street stratification is a rapid and low-cost approach for road traffic noise mapping without increasing uncertainties.

Noise pollution must be considered to achieve sustainable cities because current levels of exposure to environmental noise are a considerable risk to the health and quality of life of citizens. Urban features and sound levels were registered in 150 streets in the Chilean cities of Talca and Valdivia to analyze the relationship between both types of variables. Urban variables related to street location, urban land use, street geometry, road traffic control, and public and private transportation showed very significant correlations with the noise levels, and multiple regression models were developed from these variables for each city. Models using only urban variables in Valdivia and Talca explained 71% and 73%, respectively, of the variability of noise. The prediction error was similar in the different types of urban roads and did not exhibit significant differences between models developed in different cities. The urban models developed in one city could, therefore, be used in other similar cities. Considering the usefulness of these variables in urban planning, these models can be a useful tool for urban planners and decision-makers to implement action plans regarding noise pollution.

Urban green spaces have a beneficial effect on the health and well-being of citizens. The features of such spaces and users’ satisfaction with them determine the type and frequency of activities conducted inside parks. Understanding the relationships among these aspects is important for promoting adequate designs for these spaces. On the other hand, the limited availability of urban surface area in many cities determines the size of parks. The effect of size on people’s satisfaction and their use of parks is an aspect that has not been studied in depth in the scientific literature. Therefore, this study aimed to examine the relationships between citizens’ perceptions of the parks’ features and their uses as a function of their size. For this purpose, surveys were conducted in large and small green spaces. The results showed the importance of considering noise in the management of both types of parks to improve overall satisfaction. In addition, overall satisfaction was related to visual aspects (conservation) in large parks, and social aspects (safety and users) in small parks. Suitably designed canine and play areas in large parks and functionality for the streets surrounding small parks can contribute to reducing noise annoyance. This study showed that the size of green spaces has a positive correlation with the frequency of walking, exercising and relaxing. Furthermore, improving some environmental features would also help to increase the frequency of these activities. In this regard, the existence of groves played an important role in promoting physical activity in both types of parks, and the quality of the air and the absence of noise contributed to relaxation in large parks.

Due to the particular characteristics of hospitals, these buildings are highly sensitive to environmental noise. However, they are usually located close or within urban agglomerations. Hence, hospitals are, in many cases, exposed to high levels of environmental noise. A study of one of the main hospitals in the Extremadura region (Spain) is presented here to allow a global assessment of the acoustic impact of outdoor sound sources. Both long- and short-term measurements were carried out, and a software model was developed. The measured values exceed the World Health Organisation reference value of 50 dBA for daytime and evening, and are even higher than the 55 dBA limit at which severe annoyance is generated. Taking into account the results obtained, the noise impact on this hospital is primarily influenced by three sound sources: road traffic, cooling towers of the hospital and the emergency helicopter. Their relative importance depends on the facade under consideration. It can therefore be concluded that the overall situation of the hospital needs to be improved. Thus, a series of solutions are proposed for a possible action plan based on interventions regarding the main sound sources and the location of the most sensitive areas to environmental noise.

Noise pollution distribution in each city around the world is necessarily influenced by its own design. A lot of factor associated to urban planning have a considerable effect on volume of traffic, vehicles distribution, traffic conditions, etc. And it is know that, from a temporal and spatial point of view, the most important source of noise in cities is road traffic. For that, good relationships between urban planning and different factors such as urban density, urban morphology, urban land use, street distribution, street environment and green spaces are being founded. In this way, the fact of finding a sustainable city could be closer, at least with respect to noise pollution. A good knowledge of these relationships would allow better prediction, analysis and prevention of such pollution through an effective design of urban environments. However, although in the first decade of XXI century these relationships were treated in some works, only some aspects of these problems were considered, essentially focused on street functionality. In the last years, this topic has reached more important development and more studies focused on the analysis of the relationships between the distributions of pollution and urbanism. This work makes a revision of spatial sampling methodologies for noise pollution assessment in relation with urban planning and a review of studies that have analysed the relationships between urban noise and different specifics aspects of urban design.

Nowadays, urban design without green spaces is inconceivable. Environmental, social, and economic benefits generated by green spaces are essential to maintain the health and quality of life of the population and to control pollution. Therefore, urban planners and city leaders should know the interactions between the features of green spaces, the sociodemographic characteristics of users, and the type of use. In addition, in some studies, noise was found to be an essential factor in the perception of these green spaces. For this purpose, surveys and sound measurements were carried out simultaneously in different locations of the main green spaces of Cáceres city. The results of this study show that noise satisfaction has the greatest significant relationship with overall satisfaction with green spaces. Different features, including satisfaction with the absence of noise, can explain 71.4% of the overall satisfaction. Road traffic is the most annoying sound source, but the degree of noise annoyance is lower than that estimated for other urban environments with similar sound levels. Walking and talking activities, emotions of fear and irritability, and interruptions to conversation are most often affected by noise in these urban environments. Another conclusion obtained is that the highest significant correlation coefficients are between noise perception by users and both the equivalent continuous linear weighted sound level and sharpness. Lastly, the green-space use determines differences and significant relationships with the sociodemographic characteristics. Also, the places in green spaces where people frequently perform walking and relaxation activities have the lowest sound levels. Therefore, noise is a statistically relevant factor to be considered in the design of green spaces.

Environmental noise is a pollutant considered by the World Health Organization (WHO) as a threat to public health due to its harmful effects on human health. In this regard, the European Environmental Agency (EEA) indicates that road traffic is the sound source that generates the greatest number of people exposed in Europe to sound levels above what is recommended by the European Noise Directive. In a similar way, the EEA also reports that air pollution is the most important environmental health risk in Europe, where road traffic is one of the main sources of emission of polluting gases. The relationship between both pollutants, leads to think about the development of common strategies. This paper presents a review on recent researches about the relationship of these two types of pollution in urban environments with different types of diseases.
