Collaborated with the Indian Navy and Larsen & Toubro to develop phased array ultrasonic inspection procedures for austenite weld samples.
Designed a low-mid frequency sound absorber consisting of the parallel combination of the microperforated panel (MPP) and multiple Helmholtz resonators with the inserted neck (HRINs).
The designed acoustic absorber exhibited quasi-perfect absorption in the frequency range of 347–630 Hz.
Initially, a deep neural network-based inverse design (IDDN) methodology is developed to predict the geometric parameters of acoustic absorbers from their sound absorption characteristics.
Then the accuracy of the IDDN method is improved by proposing a convolutional autoencoder-based inverse design (ICAN) scheme.
Designed an acoustic absorber consisting of the parallel conjunction of MPP and HRs with an inserted curvy neck using autoencoder-based inverse design methodology.
An ultra-low-frequency absorber was developed, and it showed nearly perfect absorption in the frequency range of 66–100 Hz.
