Gradient modulation of structural parameters along the coupled interfaces induces rainbow trapping, where acoustic waves are spatially separated by frequency. The numerical and experimental results indicate that the acoustic waves of various frequencies are halted and magnified at distinct locations within the coupled interfaces. Compared to the bare harvester, the topological PC energy harvester markedly increases output power across a range of excitation frequencies, with a maximum amplification ratio of 91 observed in experiments. Furthermore, the topological rainbow trapping is robust against random structural disorders.

An equivalent mass-spring model using a single equivalent stiffness to represent the whole constant main pore section is proposed. This approach simplifies modeling and reduces computation time while capturing the metamaterial’s multiple resonances and visualizing mass velocities at resonance frequencies, providing insight into its acoustic behavior. Validation is carried out using thermo-visco-acoustic finite element simulations and impedance tube measurements. First, profiles with an acoustic black hole termination of one to three main pores are studied to gain insight into the formation of combined modes and their impact on absorption. Next, optimizations are performed to achieve broadband absorption, resulting in the two best profiles.

In this work, we propose a lattice-structured MPP (LMPP) with a smaller perforation size and higher perforation ratio, which demonstrates high absorption performance at the subwavelength scale. By tuning the material flow rate in a fused deposition modeling-type three-dimensional printing process, LMPPs were easily fabricated with a small perforation of 0.05 ∼ 0.4 mm in square configuration and a perforation ratio range of 0.65 ∼ 41.50 %. The fabricated LMPP showed a high sound absorption coefficient (α > 0.9) with a wider bandwidth at mid- and high-frequencies (800–4,000 Hz) owing to the lower resistance and better impedance matching on the panel surfaces. Furthermore, inhomogeneous LMPPs (iLMPPs) were fabricated by arranging LMPPs with different perforation sizes in parallel. Owing to the overlapping effect of the resonance peaks of each sub-LMPP, iLMPP exhibited broad absorption characteristic of the effective absorption bandwidth over 4,635 Hz at the first peak frequency of 2,234 Hz, resulting in an overall subwavelength (<λ/10) thickness of 11 mm.

Specifically, the acoustic field is encoded onto the phase-only profile of a phased array of transducers (PAT), enabling high-fidelity acoustic field reconstruction. Benefiting from the concept of physics-based deep learning (PBDL), we incorporate a well-defined physics rule with a generative learning method, thereby eliminating the need for an annotated POAH dataset. Moreover, a soft evaluation scheme is proposed to enhance the algorithm’s flexible exploration capability. Experimental results on various acoustic field patterns demonstrate the effectiveness of the proposed algorithm, showing superior accuracy and real-time performance in constructing acoustic holograms.

Machine learning (ML) and deep learning (DL) schemes have been presented for disease detection using voice. However, the outcomes of the system are limited due to poor spectro-temporal representation, less feature distinctiveness, low-frequency resolution problems, lower detection rates, etc. This article presents voice-based pathology using two-way voice feature representation (TWVFR), which consists of two parallel arms of a Deep Convolution Neural Network (DCNN) for feature representation. The first parallel arm considers the Mel Frequency Cepstral Coefficient Spectrogram (MFCCS), fed to 2-D DCNN to characterize the spectral domain characteristics of the voice signal. The second approach consists of multiple voice features (MVF), such as spectral domain (SD), time domain (TD), and voice quality (VQ) features. The essential features are selected using the Spider Monkey optimization algorithm and given to 1D-DCNN. The last layer features are combined and given to a fully connected layer followed by the Softmax classifier. The Softmax classifier classifies the speech signal into normal and diseased voices. The system outcomes are validated on the Saarbruecken Voice Dataset (SVD) for four class disease classifications: Bulb Paralysis, Cyste, Polyp, and Normal. The suggested TWVFR scheme provides improved overall accuracy of 98.33%, recall of 0.98, precision of 0.98, F1-score of 0.98, selectivity of 0.98, and negative predictive rate of 0.98 compared to existing methods.
