What Emoyo does

Emoyo (also referenced in source material under the operating name GeoAxon Global (Pty) Ltd and the Kuduwave brand) is a private medical-technology company headquartered in Johannesburg, South Africa, founded in 2000, that sells portable audiometry, tympanometry, and spirometry products through an e-commerce storefront and direct enterprise sales motion. The company's core product line is the Kuduwave family of clinically validated, portable screening and diagnostic audiometers — the Kuduwave Pro, Kuduwave Prime, and Kuduwave Pro TMP — which combine a headset, audiometer, and sound booth into a single lightweight device, enabling boothless audiometry through proprietary noise attenuation and real-time ambient noise monitoring.

The underlying technology is engineered for diagnostic-grade accuracy outside of traditional sound booth environments, with tele-audiology capability for remote hearing assessments. Emoyo/Kuduwave serves audiology practices, otorhinolaryngology (ENT) specialists, and occupational health programs, with the flagship Kuduwave Pro TMP also deployed aboard the International Space Station by NASA for astronaut hearing assessments. The product line is certified to FDA 21 CFR Part 11, ISO 9001, IEC 62353, ANSI/ASA S3.6, and SANS standards, enabling global market access, and is backed by a 3-year (extendable to 5-year) 'Repair or Replace' warranty with professional calibration services.

The business model combines one-time hardware sales of portable audiometer devices, recurring calibration services, and one-time software/word-list licenses, sold primarily via a direct enterprise field-sales motion with demo booking, multi-channel contact (phone, SMS, WhatsApp, email), and dedicated US and South Africa regional contact lines. Customers are predominantly B2B healthcare buyers procuring quote-based, multi-year contracts, with the company reporting cumulative sales of 3,000+ portable audiometers globally and 3 million+ hearing tests performed across its installed base.

Core offering

Emoyo is an e-commerce company that sells portable audiometry, tympanometry, and spirometry products through its online storefront. The product portfolio centers on the Kuduwave line of clinically validated, boothless portable audiometers designed to deliver hearing diagnostics without a traditional sound booth, complemented by tele-audiology solutions, speech audiometry word lists, and professional calibration services.

Product overview

GeoAxon offers the Kuduwave line of clinically-validated, portable screening and diagnostic audiometers. The product portfolio consists of three main devices: Kuduwave Pro (diagnostic audiometer), Kuduwave Prime (screening audiometer), and Kuduwave Pro TMP (with tympanometry). These devices integrate audiometer, headset, and sound booth functionality into a single lightweight unit, enabling boothless audiometry. The portfolio includes complementary speech word lists for speech audiometry testing, tele-audiology solutions for remote diagnostics, and calibration support services. The Kuduwave devices are used in clinical settings, occupational health screenings, and have been deployed by NASA aboard the International Space Station.

Direct peers

• Natus Medical: Natus manufactures electrophysiology and audiology diagnostic equipment including audiometers and tympanometers used in hospitals and clinics. Directly comparable in product category and customer base, particularly in newborn hearing screening and clinical audiology.
• Benson Medical Instruments: Benson Medical Instruments builds audiometers designed specifically for occupational health and industrial hearing conservation programs. Directly comparable to GeoAxon's occupational health vertical with competing portable and PC-based screening solutions.
• Inventis: Inventis is an Italian manufacturer of audiometers, tympanometers, and hearing aid fitting systems. Comparable product portfolio and customer base in clinical audiology and ENT, competing head-to-head with Kuduwave in mid-tier audiology clinics.
• Grason-Stadler (GSI): Grason-Stadler produces clinical audiometers, tympanometers, and OAE instruments widely used in audiology practices and ENT clinics. Sells directly into the same diagnostic and screening workflows targeted by Kuduwave Pro and Pro TMP.
• Demant (Interacoustics / Maico Diagnostics): Demant owns Interacoustics and Maico Diagnostics, both leading manufacturers of clinical and screening audiometers, tympanometers, and balance equipment. Direct overlap with Kuduwave's diagnostic and screening product lines serving the same audiology, ENT, and occupational health customers.

Emerging players

• Frye Electronics: Frye Electronics manufactures portable audiometers used in occupational hearing conservation and clinical screening. Smaller specialist player with comparable portable audiometry product positioning relative to Kuduwave Prime.
• Etymotic Research: Etymotic Research develops hearing assessment tools, earphones, and noise dosimetry equipment used in audiology and occupational health. Overlaps with GeoAxon in audiological measurement instrumentation and hearing conservation programs.
• PATH Medical: PATH Medical designs diagnostic audiology and vestibular equipment including tympanometers and ABR systems. Smaller specialist player with overlapping product categories, focused on clinical and research-grade hearing diagnostics.
• Oscilla: Oscilla produces tablet-based portable audiometers targeting screening applications in occupational health and primary care. Closely comparable form factor and use cases to Kuduwave Prime for non-booth environments.

Broad incumbents

• Welch Allyn (Baxter): Welch Allyn, now part of Baxter, is a broad incumbent in physical assessment and diagnostic medical devices. While not a focused audiometry specialist, its diagnostic instruments and global hospital sales force put it adjacent to audiology clinics and primary-care screening programs.
