Helmholtz Resonator

A Helmholtz resonator is a device that captures and amplifies specific sound frequencies. Imagine a bottle: when you blow across its top, it produces a note. In a Helmholtz resonator, there’s an opening and a cavity that work together to resonate at a particular frequency. It’s used in various applications, from musical instruments to noise control in architecture, helping to manage sound by enhancing certain pitches or dampening unwanted noise. Essentially, it acts like a musical echo chamber, focusing on particular sounds while minimizing others.
