Special Issue Information
Dear Colleagues,
Vibration and noise control is a very practical research field for a long time. In the past decade, many control methods and new materials and structures have emerged to solve the problem of low-frequency vibration and noise. For example, acoustic black holes are used to control bending waves in thin plates, acoustic metamaterials are used to achieve low-frequency broadband sound absorption and low-frequency high sound insulation, and elastic metasurfaces are used to control elastic wave transmission. The continuous exploration in this field not only enriches the basic theory of vibration and noise but also plays a huge application potential in related products in industry. This Special Issue welcomes researchers to contribute to the field of vibration and noise control, including control methods, structures, materials, and the discovery of new physical mechanisms. Vibration and noise control is a very practical research field. Because the length of low-frequency acoustic wave and elastic wave are too large for the structure size, the control of low-frequency internal vibration and noise has been a very challenging and hot research topic. Natural materials and some classical structures have been unable to meet the increasing comfort requirements. In the past decade, many control methods and new materials and structures have been developed to solve the problem of low-frequency vibration and noise. For example, acoustic black holes are used to control bending waves in thin plates, acoustic metamaterials are used to achieve low-frequency broadband sound absorption and low-frequency high sound insulation, and elastic metasurfaces are used to control elastic wave transmission. The continuous exploration in this field not only enriches the basic theory of vibration and noise but also promotes the development of physics, materials science, and other disciplines, and also has significant application potential in related industrial products. This Special Issue welcomes contributions from researchers in the field of vibration and noise control, including vibration and noise control methods, new structures, new materials, new physical mechanisms, and new experimental methods.

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. Symmetry is an international peer-reviewed open access monthly 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 2400 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.
