What IAC Acoustics does

IAC Acoustics is a UK-headquartered (Chandlers Ford, Hampshire) designer, manufacturer and installer of engineered acoustic noise control solutions, operating since 1949 as part of a broader global IAC Group ("IAC World"). Its product portfolio spans high-performance acoustic steel doors (Noise-Lock®, Super Noise-Lock®, ND-50 fire-rated), acoustic windows, fully and hemi-anechoic chambers (ISO 3745 compliant), NVH test facilities for automotive development, HVAC attenuators (Quiet-Duct™, Clean-Flow™, Conic Flow™, D-Duct™, pack-less silencers), jet blast deflectors and ground run-up enclosures for aviation, industrial acoustic barriers and enclosures (Varitone), audiology test rooms and booths, and Trackwall® movable partition systems. The company holds registered trademarks across these product lines (Noise-Lock®, Varitone, Trackwall®, Microdyne®, MusicBox®, Absorbatone®, SNAP) and maintains compliance with sector standards including EN 1634-1, ISO 3745, ISO 8253, ISO 362, ISO 354 and HTM 2045.

The business sells primarily through specification-driven direct enterprise sales, engaging architects, acousticians and consultants from design through commissioning, supplemented by an international partner network for global delivery and an in-house UK service/maintenance team. Revenue is generated across five streams: hardware product sales, turn-key installation services, recurring service and maintenance contracts, refurbishment of legacy installations, and audiology equipment leasing. Customer base is highly diversified across aviation, automotive, NVH testing, healthcare/audiology, industrial, data centres, education and music/media — with named logos spanning Dublin Airport, Draken Europe, Cambridge Acoustic Laboratory, Royal Academy of Music, Winchester Science Centre, and a luxury German automaker.

IAC Acoustics is privately held (registered in England and Wales under IAC ACOUSTIC COMPANY UK LIMITED / IAC Acoustics UK Ltd) with no disclosed institutional backing. Its recent strategic activity has focused on inorganic expansion — notably the January 2020 acquisition of Hodgson Acoustics Company and the October 2021 strategic partnership with Natus Medical Incorporated for clinical audiology solutions — alongside ongoing large infrastructure deliveries such as the Dublin Airport North Runway jet blast deflectors (2022) and the Draken Europe CF700 engine test facility refurbishment at Bournemouth.

Core offering

IAC Acoustics designs, manufactures, and installs engineered acoustic noise control products and turn-key facilities. The portfolio spans acoustic steel doors and windows (Noise-Lock®, Super Noise-Lock®, ND-50), anechoic and hemi-anechoic chambers, NVH test facilities, HVAC attenuators, jet blast deflectors and ground run-up enclosures for aviation, industrial acoustic barriers and enclosures, and audiology test rooms. Sales are specification-driven, delivered as project-based turn-key packages including design, manufacturing, installation, and commissioning.

Product overview

IAC Acoustics provides engineered noise control solutions across multiple specialized domains, operating as a comprehensive product portfolio rather than a unified platform. The core offering encompasses acoustic doors and windows (Noise-Lock®, Super Noise-Lock®, and ND-50 fire-rated acoustic doors; W-47 to W-68 acoustic windows), anechoic and hemi-anechoic chambers for precision testing, NVH test facilities for automotive development, and HVAC attenuators (Quiet-Duct™, Clean-Flow™, Conic Flow™, D-Duct™, and Ultra pals pack-less silencers). Aviation solutions include jet blast deflectors, ground run-up enclosures (GRE), and hush houses. Additional products cover industrial noise control (acoustic barriers, enclosures, absorption panels), audiology test rooms (screening booths, custom rooms, mobile units), acoustic studios and music practice rooms, reverberation rooms and transmission suites for material testing, Trackwall® movable walls, Varitone external barriers, and data centre noise control. The company also offers comprehensive service, maintenance, and refurbishment packages for its installed product base.
