Special Issue Information

Dear Colleagues,

Experimental and theoretical studies in acoustics and mechanical vibrations have gradually evolved as separate entities. The progressive fragmentation of research, together with the different civil and industrial technological applications and standardization guidelines for vibrations and acoustics, has led to the hyper-specialistic and fictitious separation of concepts and approaches.

Conversely, the integration of different perspectives, converging into the study of vibro-acoustics, would be correct from a physical perspective since it deals with the generation, propagation, and reception of mechanical waves in different frequency ranges. Moreover, it could be useful considering the multiple study domains, ranging from environmental science, ecology, biophysics, medicine, cultural heritage and archaeology to civil and industrial engineering, and the wide range of industrial applications, from the design and implementation of sensors to the design, implementation, and verifications of structures, mechanical components, machineries, aerospace and naval components, and so on.

In the emerging context of vibro-acoustic studies, a holistic and multi-disciplinary approach would be desirable to reflect not only the multiplicity of existing and potential research and application domains but also an increasing awareness of the multiple interactions between human communities and the environment. With this respect, vibro-acoustics could support new ways to interpret how tangible and intangible dimensions are shaped by interwoven anthropic (archaeological, historical, cultural, architectural) and environmental (climate, sea, mountains, wind, ground) elements, defining the evolving nature of natural and anthropized landscapes and contributing to the sustainability of cities and communities and the well-being of urban dwellers, in agreement with SDG 11 and SDG 3.

Although very attractive, this challenge presents inherent difficulties. In particular, such an emerging multi-disciplinary vision requires the development of new methods and tools, supported by measurements, analysis, and interpretations of the results, based on a converging vision on vibro-acoustics as a research discipline. In parallel, promising applications and the potential need for future integrated standardization procedures in different technological domains should be explored.

This Special Issue, entitled “Vibroacoustic Monitoring: Theory, Methods and Applications”, aims to constitute a discussion platform, that, stemming from the domain of applied physics, considering the experimental and theoretical results pertaining to vibro-acoustics, explores experimental and theoretical methods and their applications to different research fields, the integration of hard and soft metrology, the results of field monitoring activities, the wide range of research and technological applications, as well as useful insights into the domains of vibro-acoustic sensors, metrology, and standardization procedures.

Types of accepted articles include the following: articles, reporting scientifically sound experiments and providing a substantial amount of new information; communications, short articles that present groundbreaking preliminary results or significant findings that are part of a larger study conducted over multiple years; perspectives, that showcase current developments in a specific field, with emphasis on the future directions of the field and on the personal assessment of the author; reviews, offering a comprehensive analysis of the existing literature within a field of study, identifying current gaps or problems, providing recommendations for future research; and, finally, systematic reviews, presenting a detailed investigation into previous research on a given topic, using clearly defined search parameters and methods to identify, categorize, analyze, and report aggregated evidence on a specific topic.

Authors are recommended to strictly adhere to the indications provided in the Instructions for Authors (https://www.mdpi.com/journal/applsci/instructions), providing also a cover letter, during the submission process, according to the indication given by the editorial office. Microsoft World and LaTex templates are available from the same page for download.

The complex frequency domain assurance criterion is here applied for the comparison of a pristine to an altered state of a vibrating system. The criterion was originally proposed for the detection of defects in vibrating structures, while in later research studies it has been successfully used in musical acoustics. In this paper, we evaluate the differences in the vibrational behavior of finished and non-finished cymbals by adopting the proposed correlation criterion. Since idiophones are playable and produce sounds after any manufacturing process, the methodology presented correlates the vibrational state of a cymbal, at any stage of manufacturing, to a reference pristine cymbal. The evaluation of the cymbals is performed by the comparison of finished cymbals with semi-finished and blank 8-inch cymbals of the same material. The correlation criterion is applied to the vibrational measurements of blank, semi-finished, and finished B8 and B20 cymbals. Additionally, commercially available finished cymbals of the same material and geometrical characteristics are introduced in this correlation study. The measuring methodology and the vibration symmetry are discussed, and valuable results and conclusions are presented. The proposed methodology highlights the influence of the manufacturing processes of forming, hammering, and finishing on the vibrational behavior of cymbals, offering manufacturers and drummers a quantifiable criterion for evaluating cymbals’ vibroacoustic performance. Representative evaluations of blanks, semi-finished, and finished cymbals demonstrate the capability of the correlation criterion to monitor, identify, and visualize the vibrational state of any cymbal compared to a pristine reference. This enables the development of a novel methodology for both manufacturers and musicians. Full article

The ageing population and the resulting number of physical and health problems are now a major social and economic challenge around the world. Osteoarthritis is a common disease among older people. It can affect any joint, but it most often affects the knee, hip, and hand joints. Osteoarthritis of the knee joint significantly affects everyday life, limiting daily activities. Patients affected by this disease face many ailments, such as pain, stiffness, and a reduced of range of joint motion. In order to implement quick and effective treatment and prevent the development of the disease, accurate and early diagnosis is important. This will contribute to prolonging the health of the joints. Available methods for diagnosing osteoarthritis include conventional radiography, MRI, and ultrasound, but these methods are not suitable for screening. Over the years, there have been proposals to use vibroarthrography as a new, cheap, and noninvasive screening method for cartilage damage. The paper reviews recent studies on vibroarthrography as a diagnostic method for knee osteoarthritis. The aim of the study is to organise the current knowledge regarding the diagnosis of osteoarthritis of the knee joint and vibroarthrography as a proposal for a new diagnostic method. Full article
