Title: Innovations by Janet M Hogan

Introduction

Janet M Hogan is a notable inventor based in Mullica Hill, NJ (US). She has made significant contributions to the field of acoustic engineering, holding a total of 4 patents. Her work focuses on innovative solutions for sound barriers and absorbers, showcasing her expertise and creativity in this specialized area.

Latest Patents

One of her latest patents is the "Acoustic barrier support structure." This invention includes a support structure that defines a plurality of cells, a weight attached to the support structure, and at least one resonant membrane covering one of the cells. The resonant membrane can comprise at least one weight and has an anti-resonant frequency. The support structure, along with the weight, provides wide frequency band gaps between odd resonance modes while suppressing structure-membrane coupled modes, enabling the anti-resonance of the resonant membrane.

Another significant patent is the "Hybrid acoustic barrier and absorber." This invention features a rigid structure defining a cell, a membrane with at least one orifice attached to the rigid structure, and a back sheet covering the cell. The membrane is designed to reflect acoustic waves within a predetermined frequency range. Together, the rigid structure, membrane, and back sheet create a Helmholtz cavity that absorbs acoustic energy at a specific frequency within that range.
