Researchers captured sound fields around musical triangles. They wanted to understand the physical properties of the triangle instrument, test assumptions about the contribution of the triangle shape, ...

The linearity of triangular waveforms makes triangular wave generators useful in many “sweep” circuits and test equipment. For example, switched-mode power supplies and induction motor-control ...

Today we’ll take a journey into less noisy noise, and leave behind the comfortable digital world that we’ve been living in. The payoff? Smoother sounds, because today we start our trip into analog. If ...

Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...

A metamaterial elongates the propagation path of sound waves, allowing low-frequency noise control without the need for bulky materials.

For the triangle, researchers captured proof that resonance occurs even with the notched, open corner, and it may occur in other instrument shapes as well. WASHINGTON, May 6, 2025 – The triangle is a ...
