Greece, as well as other developed countries, is facing the growing problem of road traffic noise. It stands for a severe problem in the urban areas of the country, including the city of Larissa. The root cause is the huge increase in traffic volume and the lack of adequate urban infrastructure planning. Estimation of the level of road traffic noise is usually conducted using acoustic meters. It is widely accepted that most of the cities’ population is exposed to high noise levels due to controversial traffic capacity. Moreover, high noise levels are strongly related to phycological and neurological diseases. Thus, it is of utmost importance, the road noise levels to be lower than dictated by relevant specification limits. To develop better noise-environment policies, relative research should focus on the measurement of in-situ noise levels, so as appropriate for each case corrective measures to be taken. The present paper examines the noise levels of a center road of the 5th Greek city, in terms of population, compared to worldwide adopted noise specification limits. The clear aim stands for finding the percentage of road noise that exceeds commonly accepted threshold values, namely limit values of European Union and World Health Organization. The results of this research strongly indicate that measured noise values override upper limit values in a certain extent.

The most common environmental concern in metropolitan cities worldwide is noise pollution. Kota metropolis (India) is also suffering from the problem of the increased noise level in the urban environment. Kota metropolis has been selected for the assessment of noise pollution. The main reasons behind the increasing level of noise in the city are increased population, rapid urbanization and industrialization, increased transportation facilities, urban development, construction and demolition works etc. The noise levels were recorded for day-time (6 am to 10 pm) as per Indian standard time for 96 days. Sixteen sampling points are made within the city depending upon the category of area/zone such as industrial, residential, silence and commercial. Six days were prescribed for each sampling location for noise level measurement. Noise descriptors such as Lmax, Lmin, L10, L50, L90, NC (noise climate), Lnp (noise pollution level), Leq (equivalent noise level), and NEI (noise exposure index) were computed with the observed data. Noise descriptors are very useful to indicate the physiological and psychological effects of noise pollution associated with noise levels. It makes regulating agency to take necessary actions in high noise areas for noise vulnerable groups such as Childs, old persons etc. Noise levels were recorded with the digital sound level meter " HTC SL-1350". Obtained equivalent noise levels were in between 65 dB(A) to 85 dB(A). The results were then compared with the WHO standards of community noise levels, and Indian noise pollution standards. It is noticed that the noise levels in all monitoring stations were well above the limits of the standards prescribed by the WHO and CPCB. Small variations in noise levels were observed for all sampling locations i.e. noise levels were almost similar at sampling locations. Noise levels were distinct in magnitude for morning and evenings hours. Noise Exposure Index (NEI) was greater than 1 which shows significant high noise levels in all the sampling locations. Kota metropolis desperately needs new strategies to reduces the high noise level in the city. Regulating agencies should take necessary action before things get out of control. Some immediate actions are suggested in the study.

Históricamente, la casa se ha constituido como el espacio fundamental que permite la realización de las actividades domésticas, la interrelación familiar y el desarrollo y afianzamiento del yo personal. Diversos autores concuerdan que durante el siglo XX suceden las mayores alteraciones en las estructuras sociales, entornos de ciudades y en la vivienda y sus espacios (Cañar & Torres, 2018); convirtiéndose esta, en el laboratorio de experimentación teórico y de aplicación práctica de los modernos estilos de vida (Añón, 2013). En el Ecuador, las transformaciones sociales, económicas y políticas de inicios de siglo, se dieron paralelamente a las transformaciones tecnológicas y energéticas, las cuales con mayor o menor demora llegaban a Cuenca. La presente investigación plantea estudiar la modernización de la casa burguesa en Cuenca, a partir de la identificación y análisis de las estrategias proyectuales aplicadas, en la casa Peña (1954) y la casa Vázquez (1962), por el Arq. Cesar Burbano Moscoso. Estas viviendas se caracterizaron por la innovación y búsqueda de una nueva manera de habitar, asumiendo los cambios que la ciudad exigió a mediados del siglo XX. En los dos casos se evidencia como la tipología tradicional de casa con patio interior, organizada centralmente y alineada y conectada a la calzada, se invierte y muta en una tipología radicalmente contraria, compuesta por construcciones aisladas y retiradas de la calle, modificando así las relaciones, internas de la casa y con la ciudad. El estudio explora procesos arquitectónicos, enfocando el interés en reconocer criterios y valores que provienen de las obras, así como elementos arquitectónicos y urbanos de un momento particular de la arquitectura cuencana. Palabras clave: Arquitectura moderna, vivienda moderna, transformaciones del espacio doméstico, Cesar Burbano Moscoso, Cuenca-Ecuador. AbstractHistorically, the house has been constituted as the fundamental space that allows the realization of domestic activities, family interrelationship and the development and strengthening of the personal self. Several authors agree that during the twentieth century the greatest alterations in social structures, city environments and housing and its spaces took place (Cañar & Torres, 2018); becoming the laboratory of theoretical experimentation and practical application of modern lifestyles (Añón, 2013). In Ecuador, the social, economic and political transformations at the beginning of the century were parallel to the technological and energy transformations, which with greater or lesser delay reached Cuenca. This research proposes to study the modernization of the bourgeois house in Cuenca, based on the identification and analysis of the applied project strategies, in the Peña House (1954) and the Vázquez House (1962), by the architect Cesar Burbano Moscoso. These houses have been characterized by innovation and the search for a new way of living, assuming the changes  that the city demanded in the mid-twentieth century. In both cases it is evident how the traditional typology of a house with an interior patio, centrally organized, aligned and connected to the road, is inverted and transformed into a radically opposite typology, composedof isolated structures and withdrawn from the street, thus modifying the internal relations to the house and with the city. The study explored architectural processes, approaching the interest in recognizing criteria and values that come from the works, as well as architectural and urban elements of a particular moment of Cuenca architecture.

Metal Impact

Exposure to high noise levels may be the most common occupational hazard. Recent estimates suggest that as many as 30 million Americans are exposed to noise levels greater than the current safe limits for workplaces. At current durations of exposure, it is expected that 25% of these workers will develop permanent, noise-induced hearing loss. In many of these industrial environments, high levels of vibration also exist that can lead to several injuries and ailments. To address the adverse effects associated with the use of high noise emission impact tools, a study was initiated to develop and evaluate alternate tool designs that reduce the potential for hearing loss and vibration-related injuries. Recent work has focused on integrating advanced engineering polymers (composites) into tool designs for the purpose of eliminating direct metal-to-metal impact. This approach has several significant performance advantages including reduced operator discomfort due to hand-arm mechanical shock, reduced noise, and less danger from flying metal fragments. To quantify sound emission characteristics of these new designs, continuous sound pressure, maximum sound pressure, and maximum sound pressure level were measured using an array of five precision microphones each located 1 meter from the tool. Data was sampled at 40 kHz while test subjects operate both pneumatic tools and hand-struck tools. Frequency spectra of the sound pressure signals were examined for all tool treatments, and indicate that the addition of a polymer insert between metal impact components significantly reduces noise emission, especially at higher frequencies. Sound pressure levels were reduced by as much as 4 dBA compared to conventional tool designs. Similar reductions were observed in vibration transmission in the hand and arm. As a result, tools that integrate polymer-based components may be operated for longer daily exposure times without inducing hearing loss or vibration-related injuries. Data from this study may also help auditory and ergonomic specialists in understanding impulse noise characteristics and exposure.

Noise Assessment

In hospital environments, high noise levels can result in damage to patients' treatments, delaying their rest and recovery. The sound pressure level (SPL) in hospital areas during the day must not exceed 50 dB and 45 dB (A) at night, according to NBR 10.151/2019. This research aimed to carry out environmental monitoring of equivalent sound pressure levels (LAeq) at fifteen points in the vicinity of three hospitals in the central region of the municipality of Umuarama-PR, during working days, at four different times, in the months of August, September and November 2018 and continued in March 2019. To this end, we sought to map the LAeq of the points, compare them with data from municipal and federal legislation and relate the LAeq to the volume of vehicular traffic. The collected SPL were higher than recommended by NBR 10.151 at all times and measurement points, during the week, and when considering the municipal regulations, only one point is in the equipment's accuracy limit. From the statistical analysis, a very strong correlation was observed between LAeq and the total volume of vehicles, and also a strong correlation between the descriptors L10 and L50 and the volume of vehicles. The Traffic Noise Index (TNI) was also calculated and the LAeq values ​​were compared with a subjective noise rating. The results show a scenario of noise pollution in the area and there is a need for the application of mitigating measures.

Attenuation Characteristics

The noise levels of many off-the-road vehicles (ORVs) are potentially capable of causing damage to the human auditory mechanism. Most drivers of these machines refuse to wear ear protection because they contend that their helmets provide adequate attenuation. This study was designed to evaluate the attenuation of two typical recreational helmets. The results of this investigation indicated that recreational headgear alone is not sufficient protection from high noise levels. Drivers of ORVs should wear some form of ear protection in conjunction with their headgear until the noise levels of these machines are reduced.
