Article Synopsis
- Researchers examined the acoustic features and articulation involved in beatboxing, analyzing twelve drum sounds across five categories (kick, snare, hi-hat, rimshot, and cymbal).
- They collected various types of data through advanced techniques like electroglottography and acoustic recording, achieving a high cluster purity of 94% in sound classification.
- The study found significant differences in sound intensity between humming and non-humming techniques, along with the involvement of the tongue in sound production and the use of multiple airstream mechanisms.
A Convolutional Neural Network for 250-MHz Quantitative Acoustic-microscopy Resolution Enhancement.

Quantitative acoustic microscopy (QAM) permits the formation of quantitative two-dimensional (2D) maps of acoustic and mechanical properties of soft tissues at microscopic resolution. The 2D maps formed using our custom SAM systems employing a 250-MHz and a 500-MHz single-element transducer have a nominal resolution of 7 μm and 4μm, respectively. In a previous study, the potential of single-image super-resolution (SR) image post-processing to enhance the spatial resolution of 2D SAM maps was demonstrated using a forward model accounting for blur, decimation, and noise.
