Purpose: The purpose of the article is to present the concept of calculating indexes of effectiveness and acoustic efficiency of road investments that facilitate decision-making on the sequence of work implementation and the development of investment task schedule. The presented indexes are used in the development of strategic noise maps of cities and in the creation of noise protection programs. The presented concept fits into the topic of managing the acoustic climate of cities. Design/methodology/approach: The method of ranking road investments described in the article was developed based on the author's many years of experience in developing strategic noise maps of cities and presented as a case study for the city of Siemianowice Śląskie. Findings: The proposed method supports urban investment management. It allows for selecting the sequence of implementation of road investments in cities which ensures the achievement of maximum acoustic efficiency. The developed index of acoustic efficiency is defined as the ratio of costs incurred to the number of people exposed to excessive noise before and after the implementation of the investment. This index can be used to rank investments in the development of strategic noise maps and the creation of noise protection programs. Practical implications: Strategic noise maps are prepared every 5 years in accordance with EU legislation. Based on them, noise protection programs are developed, within which future investments reducing noise in the city must be identified and their effects determined. The presented concept of introducing a ranking index for investments in terms of their acoustic efficiency is a response to the cities' demand for the development of a uniform methodology supporting the selection of investments based on the criterion of acoustic efficiency. The applied method can be introduced to standardize the way of evaluating the justification of implementing noise reduction investments in cities for the purposes of developing noise protection programs. Originality/value: The article presents a concept of calculating indexes of the effectiveness and acoustic efficiency of road investments. These indexes are helpful in managing urban investments aimed at reducing the exposure of residents to noise, and in particular for proper planning of the sequence of investment implementation when developing noise protection programs. The defined indexes and the method of their calculation relate not only to road investments but can also be used to rank investments related to reducing railway and industrial noise.

The article is a substantive summary of research conducted by the Institute of Production Engineering of the Silesian University of Technology in Zabrze, covering the determination of ways to reduce traffic noise in the selected area of the city of Zabrze using measurement and simulation methods. The analysis was conducted within the Project Based Learning (PBL) project which aimed at teaching a selected group of students teamwork, synthesizing information from various sources, making decisions and taking responsibility for them, planning and organizing work and proper time management.

Classic methods of stocktaking big game living in a given area have many disadvantages. The main result is the need to ensure appropriate terrain and weather conditions and also require the involvement of a large number of people, so-called observers. The development of technology makes it possible to create new stocktaking methods that will not have as many of the above-mentioned disadvantages, while reducing the cost of stocktaking and increasing its accuracy. This paper presents an analysis of the possibility of using unmanned aerial vehicles, so-called drones, in combination with the observation of game in the infrared wave range with the use of a thermal imaging camera. The paper presents the concept of such a solution, which will of course be further developed. Raids are planned with the use of thermal cameras over areas according to strictly defined transects and subjecting the obtained images to analysis, also with the use of artificial intelligence methods. This article was written as part of the PBL project carried out by a group of students from the Silesian University of Technology under the supervision of dr inż. Arkadiusz Boczkowski.

The intensive development of sport shooting and the significant increase in the number of people using sport and recreational shooting ranges also increases the risk of hearing damage to shooters, due to exposure to impulse noise from the shots of firearms. This article discusses the methodology for assessing shooters’ exposure to noise and identifies and extensively discusses possible ways to minimise this exposure. It then describes a research experiment carried out to measure and calculate the effectiveness of noise reduction by means of acoustic silencers when shooting with typical weapons in the most popular sporting and hunting calibres. The experiment also included firing tests with subsonic ammunition. On this basis, conclusions were drawn regarding the possibility of reducing impulse noise during shooting and the possibility of eliminating the risk of hearing damage.

The article deals with the problem of acoustic modelling of sport and hunting shooting ranges for the purposes of carrying out acoustic impact assessments on the environment. The fashion for recreational shooting and the dynamic development of shooting ranges resulted in conflict situations between the shooting range and the residents. Increasingly, the condition for allowing the shooting range to be used is to carry out an acoustic analysis to confirm the lack of noise nuisance. Therefore, it is necessary to develop guidelines for acoustic modelling of shooting ranges, taking into account their purpose and types of shooting axes. Each of the shooting axes is designed for a different type of shooting and thus has different acoustic characteristics. In the article, the author presents a method of modelling noise emissions from the shooting range on the example of one of the popular shooting competitions which is the hunting trap. First, acoustic measurements of the unit noise source related to the firing of shots by a firearms shooter were made. Then the directional characteristics of this source were determined, the shooting axis of the “hunting trap” type was modelled during a typical shooting competition and its directionality was determined. Then, on the example of a specific shooting range, the possibility of using the results to analyse the propagation of noise into the environment during typical shootings on the trap axis was presented.
