Acoustic Innovations

What Acoustic Innovations does

Acoustic Innovations Co., Ltd. (株式会社アコースティックイノベーションズ) is a Japanese medical device company founded in October 2006 in Musashino City, Tokyo, currently headquartered in Fuchu City, Tokyo. The company develops acoustic wave-based respiratory therapy devices under the Lung Flute brand, which produce low-frequency acoustic waves (16-25 Hz) to facilitate respiratory mucus clearance in patients with chronic pulmonary conditions. The product line includes the original Lung Flute, the Lung Flute HR (heat-resistant, autoclavable for hospital reuse), the Lung Flute ECO (paper-based disposable), and the Lung Flute Therapeutic (PEP therapy for home use). The company has also developed DBCR, a tire vibration reduction technology that represents a non-medical diversification.

The company operates with a micro-team of 1-10 employees and a registered capital of JPY 39 million. Its technology is licensed from US partner Medical Acoustics, LLC, and the products are distributed in Japan through Eiken Chemical. Revenue is generated through two mechanisms: low-margin one-time device sales to hospitals and consumers (2,000 yen per device), and higher-margin recurring consumable/replacement kit sales (4,000 yen per 10-use kit). Since April 2016, the Lung Flute has been eligible for insurance reimbursement under J115-2 at 44 points per day, providing a stable hospital channel revenue stream. The company has also secured GHIT Fund investment and participated in JETRO and GSAP accelerator programs, indicating intentions to expand internationally and into broader global health applications.

Revenue model

1. Medical Device Sales (Lung Flute): Sale of medical devices (Lung Flute body, HR version, ECO disposable version) primarily to medical institutions. Revenue generated from initial device purchase, with consumables (mouthpieces, reeds) providing recurring revenue per patient use.
2. Consumables and Replacement Parts: Recurring revenue from disposable consumables (reeds, mouthpieces) required for each patient use. Consumable kit (10 uses) priced at 4,000 yen, translating to approximately 400 yen per patient use.
3. Lung Flute Therapeutic Consumer Sales: Direct-to-consumer sales of the Lung Flute Therapeutic for home respiratory care, sold through online medical supply catalogs at 4,000 yen with 6-month supply of replacement reeds.

Core offering

Acoustic Innovations develops and sells the Lung Flute family of Class I respiratory medical devices, which use proprietary low-frequency acoustic wave technology (16-25Hz) to liquefy and mobilize respiratory mucus for sputum induction in tuberculosis diagnosis and Positive Expiratory Pressure (PEP) therapy for chronic respiratory patients. The company also offers the DBCR tire vibration reduction coating technology as a separate automotive acoustic application. Revenue is generated primarily from device sales to medical institutions and recurring consumables (mouthpieces and reeds).

Product overview

株式会社アコースティックイノベーションズ (Acoustic Innovations Co., Ltd.) develops medical devices and acoustic technologies. The company offers two main product lines: respiratory health devices (Lung Flute family) and tire vibration reduction technology (DBCR). The Lung Flute product family includes the Lung Flute ECO (paper-based disposable for sputum induction), Lung Flute HR (autoclave-sterilizable reusable version), Lung Flute Therapeutic (PEP therapy for chronic respiratory patients), and consumable kits. All Lung Flute devices use proprietary acoustic vibration technology at 16-25Hz to liquefy and mobilize mucus in the airways. The DBCR tire vibration technology represents a separate industrial application of the company's acoustic expertise.

• Dräger: German global medical and safety technology company offering respiratory care devices, ventilators, and anesthesia equipment. Larger player with overlapping respiratory therapy product lines and broader hospital customer base.
• PARI Respiratory Equipment: Specialized manufacturer of aerosol drug delivery and airway clearance devices, including PARI O-PEP for oscillating PEP therapy. Comparable niche focus on respiratory care with established international distribution.
• Smiths Medical (ICU Medical): Global medical device company offering respiratory therapy products including PEP devices and airway clearance systems. Larger and broader portfolio than Acoustic Innovations but addresses overlapping clinical use cases in hospital respiratory care.
• Monaghan Medical: Manufacturer of Acapella and Aerobika oscillating positive expiratory pressure (PEP) devices that compete directly with the Lung Flute Therapeutic in airway clearance for COPD, cystic fibrosis, and other respiratory conditions. Established US brand with broad hospital formulary presence.
• Teleflex: Diversified medical technology company with respiratory care products including PEP therapy devices. While broader in scope, its respiratory portfolio competes with Lung Flute in hospital airway clearance.

Direct peers

• Medical Acoustics, LLC: Original US-based developer and licensor of the Lung Flute acoustic airway clearance technology. Acoustic Innovations established its business partnership with Medical Acoustics in March 2007 to begin Lung Flute sales preparation in Japan, making it the most directly comparable company in the acoustic respiratory device space.

Others

• Tire Acoustics Co. US partner company that originally collaborated with Acoustic Innovations on automotive acoustic technology R&D and continues to be involved in the DBCR tire vibration reduction technology service launched August 2021.
• Eiken Chemical Co., Ltd. Japanese diagnostics and medical device company that serves as Acoustic Innovations' primary sales distributor for Lung Flute products. Comparable in being a Japan-based healthcare company but operates in diagnostics rather than airway clearance.

Emerging players

• R. Cegla GmbH & Co. KG: German manufacturer of the G5 Shaker and other airway clearance devices, particularly the RC-Cornet. Smaller specialist player with overlapping oscillatory PEP technology competing for European and select international markets.
