AD229b: A Versatile and High-Performance Diagnostic Audiometer
The AD229b diagnostic audiometer by Interacoustics is a compact and highly efficient device designed to meet the needs of audiology professionals. Suitable for medical offices and mobile units, it ensures precise and fast hearing assessments, facilitating diagnosis and patient management for those experiencing hearing disorders.
With the ability to perform air conduction, bone conduction, and speech audiometry, the AD229b provides a comprehensive hearing evaluation. It features an automatic threshold test based on the Hughson-Westlake method, which enhances test efficiency by automatically adjusting the sound intensity according to the patient’s response. This process ensures reliable results in compliance with ISO 8253-1 standards.
The AD229b supports advanced tests such as the Stenger Test, which helps detect malingering hearing loss, and the ABLB test, used for assessing unilateral hearing loss. These features make this audiometer an essential tool for audiologists and ENT specialists.
One of the major advantages of the AD229b is its advanced connectivity. It can be linked to a PC via NOAH or OtoAccess™ software, allowing for data storage and detailed report printing. This digital management capability simplifies patient record organization and optimizes medical follow-ups.
Designed for intuitive use, the audiometer is equipped with an alphanumeric display and ergonomic controls for easy operation. Its Talk Forward and Talk Back functions ensure seamless communication between the operator and the patient, especially during soundproof booth examinations. Test monitoring can be performed via headphones or an integrated speaker, ensuring optimal control over the procedure.
The AD229b also comes with high-quality transducers, including a TDH39 audiometric headset, a B71 bone conductor, and optional EAR-Tone 5A insert earphones. These accessories ensure accurate sound reproduction while minimizing ambient noise for reliable testing.
Its lightweight and robust design, with a durable plastic casing, makes it easy to transport. A rugged carrying case is available to protect the device and its accessories during travel.
Regarding safety and compliance, the AD229b meets EN 60645-1 and ANSI S3.6 Type 2 standards for audiometers, as well as CE medical standards. It is designed for safe operation with an external UPS400 power supply, compatible with 100-240V voltages.
Finally, the AD229b allows for free-field testing, with adjustable sound levels ranging from 90 to 115 dB SPL, making it adaptable to various audiometric assessment needs.
