What Amplivox does

Amplivox Limited designs and manufactures audiological and occupational health diagnostic equipment, headquartered in Birmingham, UK, and founded in 1935 by Sir Edwin Stevens. The company's product portfolio centers on screening and diagnostic audiometers (Anova, modelONE, Model 260, Model 270, Model 270+), tympanometers (Otowave series), audiology booths, and the Amplisuite data management software with EMR integration (Noah, OtoAccess). Products are certified to ISO 13485:2016, CE-Marked under EU MDR 2017/745, and hold MDSAP certification, supporting distribution into hospitals, ENT and audiology clinics, occupational health programs, and industrial hearing conservation programs in 150+ countries.

The company is a wholly-owned subsidiary of Demant A/S, the publicly listed Danish hearing healthcare conglomerate, following its 2008 acquisition from Racal Acoustics. Revenue is generated primarily through hardware sales supplemented by calibration, repair, and extended warranty services, with a standard 2-year warranty on all products. Distribution combines direct sales (US office) with a global network of specialist distributors; in 2026, UK operations were transitioned to Diatec Diagnostics Ltd as a dedicated specialist distributor. Marketing leverages international trade shows (EUHA Congress, regional exhibitions in Central Asia and Latin America), content marketing via the Amplivox Knowledge Hub, and an active social media presence. The company employs 51-100 people and operates as a focused, heritage-driven niche medical device manufacturer within a larger diversified parent group.

Direct peers

• MedRx: US-based manufacturer of PC-based audiometers, tympanometers, and hearing aid fitting systems. Directly comparable to Amplivox in PC-based screening audiometry and clinical audiology diagnostics; also a Diatec distribution partner.
• Grason-Stadler (GSI): Manufacturer of clinical audiometers, tympanometers, and ABR/OAE systems serving ENT and audiology practices. Direct competitor to Amplivox in the diagnostic audiometry category, and also part of the Demant A/S group.
• Interacoustics: Denmark-based manufacturer of audiological and vestibular diagnostic equipment (audiometers, tympanometers, ABR/OAE). Direct competitor to Amplivox in screening and diagnostic audiometry, and notably also a Demant A/S subsidiary — making it an intra-group competitor.
• MAICO Diagnostics: German-headquartered manufacturer of screening and diagnostic audiometers, tympanometers, and ABR devices. Directly comparable to Amplivox in screening/diagnostic audiometry for both clinical and occupational health customers.
• Inventis: Italian manufacturer of audiological and vestibular diagnostic equipment including audiometers, tympanometers, and video head impulse systems. Direct peer in diagnostic and screening audiology, also distributed via Diatec alongside Amplivox.

Broad incumbents

• Otometrics (GN Hearing): Division of GN Hearing (Demant competitor) manufacturing clinical audiology, vestibular, and hearing aid fitting equipment. Overlaps with Amplivox in diagnostic audiometry but operates a broader audiology/vestibular portfolio.
• Welch Allyn (Hillrom / Baxter): Large incumbent manufacturer of physical and sensory diagnostic devices used in primary and occupational care; provides overlapping but broader clinical diagnostic capabilities relative to Amplivox's audiology focus.
• Natus Medical: Diversified medical device company with a hearing screening and diagnostics business (newborn hearing screening, OAE/ABR). Overlaps with Amplivox in the hearing screening category, particularly occupational and clinical screening.

Emerging players

• Etymotic Research: Specialist in hearing assessment and hearing protection products (earphones, audiometric accessories, noise-attenuating headsets). Adjacent peer to Amplivox in occupational hearing screening accessories like Audiocups.
• Path Medical: Germany-based specialist in diagnostic audiology, newborn hearing screening, and OAE/ABR devices. Comparable niche peer to Amplivox in screening and diagnostic audiometry with a more focused product set.
