Special Issue Information

Dear Colleagues,

Machine noise is becoming more and more important due to increased power density of machines and stricter requirements for permissible noise levels. The development of strategies to reduce vibroacoustic hazards should involve efforts to reduce noise emission and exposure to vibration and noise. In this context, knowledge about vibrations and machinery noise is needed for modern research and calculation methods.

Machinery noise and vibrations occur primarily due to dynamical processes during the machine’s operation. Among the many causes of the noise, mechanical, liquid flow, and aerodynamic origins have been mentioned.

This Special Issue welcomes recent research papers on key topics concerning machinery noise. We encourage the submission of manuscripts that focus on, but are not limited to, the following topics:

  • Machinery noise sources and their location;
  • The measurement of vibroacoustic processes in machines;
  • Novel approaches for machinery vibration and noise modelling;
  • Noise emission from stationary and mobile machines;
  • Methods for controlling machinery noise; active noise control.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Acoustics is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Determining reliable noise emission values for machinery is key to successfully implement the Sell and Buy Quiet concept. ISO 11202 is a basic noise emission standard to determine the emission sound pressure level of machines outside of special acoustic test rooms (in situ measurements) and enables machinery manufacturers to determine the noise emission data of their products within their own premises. However, a recent amendment to this standard was made on the basis of an unsatisfactory amount of experimental data. Therefore, this paper systematically examines the validity and accuracy of the amended part of the method. It answers the question, whether the amendment represents an improvement of the existing method. Measurements on a model machine with two configurations allow for an extensive investigation of the effects of the amendment. To that end, the emission sound pressure levels at eight positions near the machine are determined in three different acoustic environments. One finds that the amendment leads to an overestimation of the local environmental correction for the LpA, which, in turn, could lead to an underestimation of the determined emission sound pressure level.
