Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.

The proximity effect refers to the way that the low-end frequency on a microphone increases the closer it gets to the source of the sound—the closer to the mic, the greater the boost in the bass. As ...

The circuit was created to produce an oscillator operating at low frequency for use in the production of electronic music and experimenting and testing tone controls. Oscillator – an electronic ...

The circuit was designed to create a two-way loudspeaker with the use of a tweeter for producing high frequency or pitch signals and a woofer for producing low frequency or bass signals. Different ...
