Acousticon Hörsysteme GmbH

What Acousticon Hörsysteme GmbH does

Acousticon Hörsysteme GmbH is a privately held German manufacturer of audiologic measurement and fitting systems, founded in 1984 and headquartered in Reinheim, southern Hesse (Südhessen). The company develops, produces, and distributes modular computer-assisted fitting systems for hearing aid acousticians, with its core product being the ACAM5 — the fifth generation of the Acousticon-Computerunterstützte-AnpassMessung platform, originally launched in 1988. The ACAM5 architecture supports multiple proprietary fitting procedures, notably Acousticon-LoudnessFitting (ALF) for loudness-based hearing system fitting, trueLOUDNESS (a world-first binaural broadband loudness summation measurement developed with Hörzentrum Oldenburg), and revoloud. In 2023 the company expanded its offering with smartALF, an interactive, guided fitting technology that runs on a PC or tablet with internet connection and the A2000 free-field headphone. Complementary products include CARL (a simulation patient for training), audiologic measurement equipment (AS03/AS04 probes, modular couplers), db99 loudspeaker systems, and ongoing software updates (latest ACAM5 version 5.22.23 with NOAH4 interface released February 2026).

The company sells primarily to Hörakustik-Fachbetriebe (independent hearing aid specialist businesses) and research institutions and university clinics across Germany, Austria, and Switzerland, with international reach into Spain via distribution partner AUDIAS Instituto Auditivo. Revenue is generated through a mix of one-time hardware/equipment sales (e.g., smartALF system at €6,950), annual ACAM service contracts (MTK) including software updates, training and education services, and a startup support program for hearing acoustics entrepreneurs. Customer engagement combines direct consultative sales, deep annual presence at the EUHA Congress, online training programs, and a closed LinkedIn community group for trueLOUDNESS users. The company operates with approximately seven employees and is led by a dual leadership structure (Harald Bonsel and Christopher Bonsel) representing its family ownership, with no disclosed institutional investment. Strategic research collaboration with Hörzentrum Oldenburg and a co-marketing partnership with hearing aid OEM Signia at EUHA 2024 indicate ongoing investment in clinical validation and ecosystem positioning.
