This study is aimed to evaluate a method for distinguishing between healthy and pathological voices. The evaluation was carried out using several acoustic parameters including COVAREP (collaborative voice analysis repository for speech technologies), the auditory-perceptual RBH (roughness, breathiness, hoarseness) scale, and AVQI (acoustic voice quality index). Finally, a classifier is trained using machine learning algorithms from the WEKA (Waikato Environment for Knowledge Analysis) platform. The study group comprised 75 voice recordings of individuals affected by vocal fold paralysis. The control group consisted of 49 voice recordings of healthy individuals. The results indicate that the voice quality of the study group is significantly different than the voice quality of the control group. Acoustic parameters implemented in COVAREP and the RBH scale have proven to be reliable methods assessing voice quality. In addition, data classification achieved over 90 % accuracy for every classifier.

In industrial plants noise is a major threat to the mental and physical health of employees. The risk increases more due to the presence of high noise sources and the presence of too many employees in textile industry plants. This paper aims to predict the consequences of variables that may arise in the plants for acoustic improvement in textile industry plants. For this purpose, scenario plants have been created according to architectural properties and source-transmission path-receiver characteristics. The acoustic analyses of the scenario plants were performed in the ODEON Auditorium, and A-weighted sound pressure level (LA), noise reduction (NR), and reverberation time (RT) were determined. From the data, prediction equations were created with a multiple linear regression (MLR) model. To test the prediction equations, acoustic measurements were made, and acoustics improvements were carried out at a textile industry plant located in Türkiye. When the obtained results, the success, validity, and reliability of the prediction method are provided. In conclusion, the effect of architectural properties and the surface absorption on acoustic improvements in the textile industry was revealed. It was emphasized that prediction methods can be used to determine the effectiveness of interventions that can be applied in different facilities and can be improved in future studies.

Imaging based on the photoacoustic (PA) phenomenon is a type of hybrid imaging approach that combines the advantages of pure optical and pure acoustic imaging, achieving good results. This method, which offers high resolution, suitable contrast, and non-ionizing radiation, is valuable for the early detection of various types of cancer. Recently, multiple studies have focused on improving different components of this imaging system. In this presentation, we implemented a simplest form of a PA imaging system for detecting blood vessels, given that angiogenesis is recognized as a common symptom of many cancers. For the first time, we implemented a highpower light-emitting diode (LED), to replace bulky and expensive lasers, and integrated circuit technologies such as field-programmable gate arrays (FPGAs) for a simple LED driver circuit and data acquisition (DAQ). Using an FPGA block, we successfully generated a 200-ns square pulse wave with a repetition frequency of 25 kHz, whose amplified form can drive a high-power LED at 1050 nm for appropriately stimulating the sample. By using ultrasonic sensors with a central frequency of 1 MHz and a DAQ system with 16-bit accuracy, along with a suitable algorithm for image reconstruction, we successfully detected blood vessels in a breast tissue mimic. With the use of the FPGA-based block, the image reconstruction algorithm was accelerated. Finally, the simultaneous and first-time use of LED and FPGA-based circuit technology for driving the LED, output information processing and image reconstruction were performed in PA imaging.

The paper presents the characteristics of the sound field in two pairs of coupled reverberation rooms, designed in accordance with International Organization for Standardization [ISO] (2021c). The analyses are based on the results of the following studies. Firstly, the acoustic airborne sound insulation of selected test samples was measured in the reverberation rooms without using any sound diffusing nor sound absorbing elements. In the second step, the tests were repeated successively with an increasing number of diffusers installed in the rooms. The last stage of the research involved measurements with additional absorbers mounted in the rooms. The results show that although the geometry and construction of the reverberation rooms are in line with the standard guidelines, in most situations it was necessary to use diffusing and absorbing elements to improve the acoustic field in the rooms. Such elements, however, are very undesirable as they significantly limit the usable space of the rooms, making it more difficult to assemble samples and distribute sources and measurement points in the measurement space. Later in the article, the authors prove that even using typically available design tools, i.e., 1st and 2nd Bonello criterions, numerical simulations with the image-source method and the finite element method, or more advanced research methods, such as measurements using scaled samples, it seems impossible to prevent at the design stage the future necessity of using additional diffusing and absorbing elements in the reverberation rooms. Only via verification by measurements performed in the completed rooms provides the assessment if such additional elements are required.

The half-wavelength spacing arrangement of underwater uniform linear arrays has been widely used for better anti-interference performance and higher signal gain. However, practical challenges of small element spacing, numerous elements, high hardware costs, large data storage requirements, high processing complexity, and mutual coupling effects between elements, have hindered its widespread use. This paper proposes an under-sampled array signal reconstruction method based on the compressed sensing (CS) theory in the element domain. This method is not limited by the array configuration and constructs a deterministic measurement matrix that satisfies the restricted isometry property (RIP). based on the array configuration, to ensure reconstruction performance. The method uses a two-dimensional orthogonal matching pursuit (OMP) method for time-space joint reconstruction of under-sampled spatial signals. Our simulation and practical test data processing results demonstrate that this method can achieve high-precision reconstruction of under-sampled array element domain signals at low under-sampling rates and can reconstruct full array signals with minimal error. Even under low signal-to-noise ratio (SNR) conditions, offering a practical and efficient solution to the challenges of underwater acoustic array signal processing.

Binaural audio technology has been in existence for many years. However, its popularity has significantly increased over the past decade as a consequence of advancements in virtual reality and streaming techniques. Along with its growing popularity, the quantity of publicly accessible binaural audio recordings has also expanded. Consequently, there is now a need for automated and objective retrieval of spatial content information, with ensemble location and width being the most prominent. This study presents a novel method for estimating these ensemble parameters in binaural recordings of music. For this purpose, a dataset of 23 040 binaural recordings was synthesized from 192 publicly-available music recordings using 30 head-related transfer functions. The synthesized excerpts were then used to train a multi-task spectrogram-based convolutional neural network model, aiming to estimate the ensemble location and width for unseen recordings. The results indicate that a model for estimating ensemble parameters can be successfully constructed with low prediction errors: 4.76(±0.10) for ensemble location and 8.57 (±0.19) for ensemble width. The method developed in this study outperforms previous spatiogram-based techniques recently published in the literature and shows promise for future development as part of a novel tool for binaural audio recordings analysis.

A method is proposed to estimate the bubble void fraction and bubble size distribution in marine sediments based on measured sound speed and attenuation data in gas-bearing sediments. The new inversion approach employs an effective density fluid model, corrected for gas bubble pulsations, as the forward model and represents the unknown gas bubble size distribution using a finite sum of cubic B-splines. An in situ acoustic monitoring experiment was conducted at an intertidal site in the Yellow Sea to investigate gassy sediments and validate the method. The measured sound speed and attenuation show significant fluctuations due to bubble resonance, with resonance peaks shifting to higher frequencies as water depth and hydrostatic pressure increase. This method simultaneously estimates the bubble size distribution from sound speed and attenuation data.

The purpose of this work was to examine the impact of the inadequacies in the current procedure for car tyre labelling, specifically in the context of environmental noise, and to present the benefits of adopting more realistic procedure with the use of low-noise tyres. This was done using two approaches: an impact analysis and a cost-benefit analysis. The calculations were performed to show this impact on environmental noise. This was done using the common noise assessment methods in Europe (CNOSSOS-EU) model (recommended for strategic noise mapping of EU countries), which was validated using test results from sound exposure level measurements on both ISO test track and on real road sections. Using the noise calculation results, a costbenefit analysis was performed, incorporating financial analyses of both the current and projected situation under different strategies to reduce tyre/road noise.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a prevalent and detrimental chronic condition. The conventional diagnostic approach for OSAHS is intricate and costly. Snoring is one of the most typical and easily obtained symptom of OSAHS patients. In this study, a series of acoustic features are extracted from snoring sounds. A fused model that integrates a deep neural network, K-nearest neighbors (KNN), and a random under sampling boost algorithm is proposed to classify snoring sounds of simple snorers (SSSS), simple snoring sounds of OSAHS patients (SSSP), and apnea-hypopnea snoring sounds of OSAHS patients (APSP). The ReliefF algorithm is employed to select features with high relevance in each classification model. A hard voting strategy is implemented to obtain an optimal fused model. Results show that the proposed fused model achieves commendable performance with an accuracy rate of 85.76%. It demonstrates the effectiveness and validity of assisting in diagnosing OSAHS patients based on the analysis of snoring sounds.

The voiced parts of the speech signal are shaped by glottal pulse excitation, the vocal tract, and the speaker’s lips. Semantic information contained in speech is shaped mainly by the vocal tract. Unfortunately, the quasiperiodicity of the glottal excitation, in the case of the HFCC parameterization, is one of the factors affecting the significant scatter of the feature vector values by introducing ripples into the amplitude spectrum. This paper proposes a method to reduce the effect of quasiperiodicity of the excitation on the feature vector. For this purpose, blind deconvolution was used to determine the vocal tract transfer function estimator and the corrective function of the amplitude spectrum. Subsequently, on the basis of the obtained HFCC parameters, statistical models of individual Polish speech phonemes were developed in the form of mixtures of Gaussian distributions, and the influence of the correction on the quality of classification of speech frames containing Polish vowels was considered in details. The aim of the introduced solution was to narrow the GMM distributions, which clearly, according to the detection theory, reduces classification errors. The results obtained confirm the effectiveness of the proposed method.

Although noise and vibration measurements are widespread in the machine diagnostics, they are not used in the diagnostics of the powertrain of motor vehicles. Our research aims to investigate the possibilities, advantages, and drawbacks of using noise and vibration diagnostics performed for motor vehicles. In this paper, we attempt to use vibroacoustic signals from a motor vehicle for diagnostic purposes. Ordinary audible malfunctions, for example, misfiring in a passenger car, were artificially created. The differences between the normal and faulty operating conditions were examined to identify evidence of failure in the vibration signal. Primarily, evaluation through Fourier transformation was performed to provide a visual correlation between the fault and the vibration behavior of the car. Detailed conclusions from the measurements and future research plans are discussed.

A recent key challenge in noise engineering is the development of structures or materials that achieve desirable acoustic performance in practical settings. Combinations of porous layers and perforated plates offer potential composite absorbers for various acoustic applications. The present work conducts experimental characterizations of sound absorption performance of absorbers based on membrane foams combined with perforated plates. Membrane foams with the well-controlled cell size and porosity are fabricated by milli-fluidic tools, whereas perforated plates are made within a tuned perforation ratio. The three-microphone method is used to perform the acoustic measurements. The results obtained from ten combination samples reveal that the sound absorption behavior of the foam-based layers can be successfully tailored and improved by a thin perforated plate within a reasonable hole diameter and spacing while maintaining the total thickness of the composite absorber.

The acoustic behaviour of a classroom is vital for an effective teaching-learning process. The present work aims to experimentally determine the acoustic performance of a typical classroom. The full-scale experiment was conducted at the Seminar Hall, the Department of Applied Mechanics, MNNIT Allahabad, Prayagraj, using a method with limited resource requirements. The Seminar Hall was divided into four planes by threads, and the sound pressure level (SPL) was measured at 30 coordinates in each plane for the specified sound source location. Data were collected from three different sound source locations. The study revealed that the sound source location and frequency significantly influence the sound pressure levels in the classroom, impacting its acoustic performance. The broader implications of interior materials, such as wall material and the position of elements like the teaching board, door, and podium, are highlighted as critical considerations for future classroom acoustic optimization. Furthermore, a numerical model was developed to predict the variation in the SPL with change in the sound source locations and frequencies. The collected data validated with the finite element (FE) model. The verification experiments for the modeling results were performed for each plane. The results of the FE model and experiments were found consistent across all four planes of the seminar hall and the various sound source locations.

Two-dimensional transition metal dichalcogenides (MoX2, where X = S, Se, Te), have been the research hotspot over the past decade. The sonication-assisted liquid-phase exfoliation method is suitable for the mass production of MoX2 in practical applications. Water and ethanol, rather than organic solvents, are increasingly chosen for liquid-phase exfoliation method due to their non-toxic, environmentally friendly properties. However, a systematic review of the method for MoX2 preparation using water and ethanol is lacking. In this paper, recently published work on the sonication-assisted exfoliation method for MoX2 preparation using water and ethanol is summarized. Three key parameters are focused on: solvents selection, sonication power, and sonication time. Finally, the application of MoX2 flakes and the future outlook of the sonication-assisted liquid-phase exfoliation method using water and ethanol are presented. The review aims to provide guidance on exfoliating MoX2 using the sonication-assisted exfoliation method with water and ethanol.
