Article Synopsis
- - The Lambert diffuse reflection model is crucial for predicting sound behavior in both indoor and outdoor environments, revealing differences in reflection strength between diffusely and specularly reflecting walls.
- - Borish highlighted that a diffusely reflecting wall produces a stronger reflection (3 dB) than a specular wall when the source and receiver are aligned in a specific way, which raises questions about energy distribution.
- - The research clarifies that the difference in perceived reflection strength relates to the type of receiver used and confirms that energy conservation is upheld, providing a better understanding of the Lambert reflection model's implications.
Background: Inflammatory bowel disease (IBD) is characterized by recurrent inflammation of the gastrointestinal tract and has been linked to an imbalance in gut bacteria. Synbiotics, which combine probiotics and prebiotics, are emerging as potential IBD treatments.
Aim: To examine the effects of four synbiotic formulations on intestinal inflammation and peripheral biomarkers in a rodent IBD model of both sexes.
Article Synopsis
- - This research introduces a technique utilizing a residual neural network and a single-layer microphone array to accurately predict sound absorption coefficients for finite porous absorbers, addressing limitations caused by their size.
- - The method involves generating training data through a boundary element model and teaches the network to estimate sound absorption as if the material were infinite, improving predictions across various absorber dimensions and conditions.
- - Results show that this approach performs comparably to the traditional two-microphone method, especially excelling at low frequencies (below 400 Hz) and for smaller absorbers, offering a practical on-site measurement solution despite edge diffraction effects.
The course "Acoustical Measurement Techniques TTT4250," offered by the Acoustics Group at the Department of Electronic Systems, Norwegian University of Science and Technology, is a fourth-year course in the specialization of acoustics in the five-year master program "Electronics Systems Design and Innovation" or MTELSYS, and the two-year international master program "Electronic Systems Design" or MSELSYS. It is one of the four required courses for MTELSYS and one of the two required courses for MSELSYS. It offers a hands-on approach to acoustics.

Previous research has demonstrated subjective benefits of audio spatialization with regard to speech intelligibility and talker-identification effort. So far, the deliberate activation of specific perceptual and cognitive processes by listeners to optimize their task performance remained largely unexamined.
