Disclosed herein are implementations of acoustic metamaterial structures and geometric configurations of acoustic metamaterial structures which produce sound amplification or cancellation. An acoustic metamaterial device for using with a sound source includes a plurality of fins, where each fin is made from a very dense material with respect to air which creates the anisotropic properties of the acoustic metamaterial device, where each fin has a length dimension, a width dimension, and a thickness dimension, the width and length dimension being equal and substantially perpendicular to the direction of sound wave propagation from the sound source, where each fin is sized different from other fins along the width and length dimension, and where the plurality of fins are interconnected such that planes formed by the width and length dimension of each fin faces perpendicular to the sound wave propagation direction from the sound source.

Acoustic metamaterial structures and geometry for sound amplification and/or cancellation

Disclosed herein are implementations of devices and methods for side mounting of microelectromechanical systems (MEMS) transducers on tapered horn antennae. A hole is made in a sidewall of a tapered horn antenna, where the hole is substantially cylindrical, tapered and the like. In an implementation, an internal port opening of a MEMS microphone is aligned with the hole and attached to the sidewall of the tapered horn antenna. In an implementation, the hole is tapered with a diameter at one end, either the same or slightly larger than the diameter of the port opening of the MEMS microphone and a larger diameter at another end of the hole. In an implementation, a tube is used to connect the internal port opening of the MEMS antenna to the hole in the tapered horn antenna. In an implementation, the tapered horn antenna may have multiple holes, each having its respective MEMS transducer.
