Intended Use

The Amplaid A311 Series is a clinical diagnostic audiometer which can perform all audiometric tests normally performed in a clinical situation. It is intended for use by a qualified/trained audiologist on both adult and pediatric subjects for measurement and diagnosis of various types of hearing losses.

Device Story

Amplaid A311 Series is a two-channel clinical diagnostic audiometer; performs audiometric tests including pure tone, speech, Multifrequency, S.I.S.I., A.B.L.B. (Fowler), D.L.I. (Lüscher), M.L.B., and Tone Decay. Used in clinical settings by audiologists for evaluation of cochlear, retrocochlear, central dysfunction, and non-organic hearing loss. Two models: AM11 (PC-based interface via RS232) and A311 (dedicated front panel keyboard with LCD). Both share identical internal circuitry. Output provides diagnostic data for hearing loss assessment; aids clinicians in determining appropriate patient treatment plans.

Clinical Evidence

Bench testing only. Performance verified against established audiometric standards (ISO 389-1989, ANSI S3.6-1989, IEC 60645) and electrical safety standards (UL 2601, IEC 60601-1). No clinical trial data presented.

Technological Characteristics

Two-channel clinical diagnostic audiometer. Energy source: 115/230 Vac, 50-60 Hz. Connectivity: RS232 for PC interface (AM11 model). Standards: ISO 389-1989, ANSI S3.6-1989, IEC 60645, UL 2601, IEC 60601-1. Models: AM11 (PC-controlled) and A311 (integrated LCD/keyboard).

Indications for Use

Indicated for use by qualified/trained audiologists on adult and pediatric patients for the measurement and diagnosis of various types of hearing losses.

Regulatory Classification

Identification

## 510(k) Summary of Safety and Effectiveness

- Identification of the Device: 1. Proprietary-Trade Name: "Amplaid A311 Series™ "(AM 11, A311) Classification Name: Audiometer 77EWO Common/Usual Name: Clinical Audiometer
- Equivalent legally marketed devices This product is similar in design and function 2. to the Amplaid 309 Clinical Audiometer (K880059), Amplaid 308 Clinical Audiometer (K891988), and Amplaid A460 (K971747)
- Indications for Use (intended use) The Amplaid A311 Series is a clinical diagnostic 3. audiometer which can perform all audiometric tests normally performed in a clinical situation. It is intended for use by a qualified/trained audiologist on both adult and pediatric subjects for measurement and diagnosis of various types of hearing losses.
- Description of the Device: The Amplaid A311 Series is a two channel clinical 4. diagnostic audiometer which can perform all audiometric tests normally performed in a clinical situation. It provides testing capability for basic evaluation, cochlear versus retrocochlear dysfunction, central dysfunction and non-organic hearing loss. Other diagnostic audiometric tests are: pure tone, speech, Multifrequency, S.I.S.I., A.B.L.B. (Fowler), D.L.I. (Lüscher), M.L.B., and Tone Decay. The A311 Series comes in two models, both using the same internal circuit board: The AM11 which uses a personal computer as the user interface (communicates via RS232), and the A311, with uses a dedicated front panel keyboard with an LCD display.
- Safety and Effectiveness, comparison to predicate device. The results of bench ર and user testing indicates that the new device is as safe and effective as the predicate devices.
