  - Advances in Intelligent Systems and Computing - Rok 2016

  Music Information Retrieval (MIR) area as well as development of speech and environmental information recognition techniques brought various tools in-tended for recognizing low-level features of acoustic signals based on a set of calculated parameters. In this study, the MIRtoolbox MATLAB tool, designed for music parameter extraction, is used to obtain a vector of parameters to check whether they are suitable for separation of...

  • G. Ronowski

  - Rok 2015

  Sports, hunting and military shooting grounds are well known sources of noise that can be disruptive both for people present at those facilities, as well as for people and animals that live nearby. What is more, shooters are also subjected to very painful and dangerous impulse noise. The paper discusses the issues related to the noise immission during firing of small firearms of military type that are typical for Poland. The experiments...

• Traffic Noise Analysis Applied to Automatic Vehicle Counting and Classification

  Publikacja

  • K. Marciniuk
  • B. Kostek
  • A. Czyżewski

  - Communications in Computer and Information Science - Rok 2017

  Problems related to determining traffic noise characteristics are discussed in the context of automatic dynamic noise analysis based on noise level measurements and traffic prediction models. The obtained analytical results provide the second goal of the study, namely automatic vehicle counting and classification. Several traffic prediction models are presented and compared to the results of in-situ noise level measurements. Synchronized...

• COMPARISON OF NOISE EMISSION OF HCT AND CLASSIC VEHICLE COMBINATIONS FOR TIMBER TRANSPORTATION IN SWEDEN

  Publikacja

  • U. Sandberg
  • S. Kharrazi
  • P. Mioduszewski

  - Rok 2018

  By means of a special simulation tool, the noise emission of a high-capacity heavy vehicle (11 axles) was compared to that of a classic heavy vehicle (a truck-dolly-semitrailer with 8 axles). The two cases are designated “Extended vehicle” versus “Classic vehicle” in this study, having total lengths of 34 and 25 m, respectively. The Classic vehicle represents the most common articulated heavy vehicle configuration for transport...

  - Rok 2019

  The recently published ISO standard intended to measure the noise properties of road surfaces in a standardized method (ISO 11819-2:2017) precisely defines measurement procedure of the influence of road surface on traffic noise. According to it, two types of test vehicles may be utilized: a self-powered vehicle fitted with one or more test tyres and a trailer towed by a separate vehicle with one or more test tyres mounted on the...

• Driver influence on tyre/road noise generated by vehicle in road traffic.Wpływ kierowcy na hałas generowany przez pojazd w ruchu drogowym.

  Publikacja

  • S. Taryma
  • R. Woźniak

  - Rok 2004

  W pracy omówiono wkływ stylu jazdy kierowcy oraz stanu technicznego wybranych zespołów pojazdu na jego hałas generowany w ruchu drogowym. Wpływ został przeanalizowany w aspekcie takich parametrów, jak: prędkość jazdy, obciążenie kół siłami wzdłużnumi i poprzecznymi, ciśnienie w ogumieniu, obciążenie pionowe kół, zbieżność i inne.

• Classifying type of vehicles on the basis of data extracted from audio signal characteristics

  Publikacja

  • K. Marciniuk
  • B. Kostek
  • A. Czyżewski

  - Journal of the Acoustical Society of America - Rok 2017

  The aim of this study is to find and optimize a feature vector for an automatic recognition of the type of vehicles, extracted form an audio signal. First, the influence of weather-based conditions of road surface on spectral characteristic of the audio signal recorded from a passing vehicle in close proximity to the road is discussed. Next, parameterization of the recorded audio signal is performed. For that purpose, the MIRtoolbox,...
