Using intricate geometry found in nature and refined through aerospace and biomedical design, scientists have now 3D-printed ...

Learn about the best materials and methods for sound insulation of motors and generators, and how to apply them in different situations.

New architecture could be used to create tailored devices that emit or receive only certain frequencies of sound ...

We relocated for work and are struggling with the noise. How much could soundproofing cost and is planning permission needed?

The pitch of the sound depends on the frequency at which the rays are interrupted, and its strength on the ability of the gas to absorb infra-red rays.

Quantum dots beat traditional photosensitizers at their own game. They tackle reactions once thought too tough for ...

A weakly conditionally stable finite-difference time-domain (WCS-FDTD) method is used to simulate a graphene-based absorber. By using the auxiliary differential equation and Padé fitting method, both ...

Claudio de Sanctis sees a need for more financial innovation to bring blue-economy investments into the mainstream.

However, through sound processing using time–frequency analysis methods such as the Short-time Fourier Transform and Continuous Wavelet Transforms, we hope to enhance the signal-to-noise ratio for ...
