Acoustic Isolation Booth
Patent Number: US 11427999 Grant Date: 2022-08-30 Filing Date: 2021-02-19
Overview
Filed in February 2021 (Feb. 19, 2021) and granted in August 2022 (Aug. 30, 2022), this patent protects a purpose-built acoustic isolation booth designed to deliver private, low-transmission spaces while preserving controlled voice communication. Drafted for clarity and breadth, the claims cover a multi-compartment shell with an intermediate wall, engineered openings and an arched ceiling that together balance acoustic transmission with physical separation. The applicants and inventors are based in Amarillo, TX; the specification details construction using layered retaining boards (Masonite) and Rockwool insulation, optional intermediate chamber windows, integrated shelves, and configurable front enclosures. The prosecution emphasizes both structural and acoustic innovation, including an intentional sound gap beneath an arched roof to channel reflected sound between compartments without direct air exchange.
The patent also claims active masking measures: embedded speakers can play a sibilance interference track (about 60 dB) to disrupt eavesdropping while allowing occupants to communicate through reflected sound paths. The resulting design is suited to clinical triage, recording booths, and modular privacy installations where infection control and acoustic discretion are priorities.
Key Features
- Dual-compartment shell with intermediate wall and optional viewing window
- Arched ceiling and sound gap that channel reflected sound while limiting direct transfer
- Masonite retaining boards with Rockwool insulation for high isolation
- Integrated speaker-based sibilance masking (≈60 dB)
By combining passive construction details with active masking and an arched acoustic path, the invention bridges building construction and audio engineering, addressing privacy and health concerns across healthcare, broadcast, and modular building markets.
Invention Details
Abstract: An acoustic isolation booth for providing a space for noisemaking out of earshot from other parties. wherein: the acoustic isolation booth comprises a shell comprising at least two compartments, an intermediate wall, a plurality of outer walls, a ceiling and one or more entryways. The shell comprises a shell width, a shell depth and a shell height. The two compartments comprise at least a first compartment and a second compartment. each of the two compartments comprises a compartment depth, a compartment width and a compartment height. A first side wall, the intermediate wall and a second side wall are configured to divide a space within the shell into the first compartment and the second compartment.
Summary of the Invention: An acoustic isolation booth for providing a space for noisemaking out of earshot from other parties. wherein: said acoustic isolation booth comprises a shell comprising at least two compartments, an intermediate wall, a plurality of outer walls, a ceiling and one or more entryways. Said shell comprises a shell width, a shell depth and a shell height. Said two compartments comprise at least a first compartment and a second compartment. each of said two compartments comprises a compartment depth, a compartment width and a compartment height. A first side wall, said intermediate wall and a second side wall are configured to divide a space within said shell into said first compartment and said second compartment. Said plurality of outer walls and said intermediate wall comprises a thickness. Said intermediate wall comprises an intermediate wall height. portions of said shell is constructed of a composition. such as, said intermediate wall, said ceiling, said first side wall, said second side wall and sometimes, a shelf. Said composition comprises an insulation, two retaining boards. Said two retaining boards comprises a first board and a second board. Said two retaining boards comprises Masonite. Said insulation comprises Rockwool.
