Indications for Use

The Grason-Stadler Inc. model GSI 70 AudioPath™ Hearing Screener is similar to and predicated upon the Grason-Stadler Inc. model GSI 60 Otoacoustic Emissions/Screening Audiometer, the GSI 37 Auto Tymp Middle Ear Analyzer, and the GSI 17 Pure Tone Screening Audiometer. The purpose of this device is to detect as well as track hearing loss and abnormal middle ear conditions in all ages of patients (from premature infants through adults). The instrument has combined a battery of testing capabilities such as Otoacoustic Emission Screening, Tympanometry, and Pure Tone Audiometry within one hand held instrument. The device is intended to be used by trained personnel within a medical or school environment. This device is not intended for use in prescribing or fitting assistive listening devices such as hearing aids, cochlear implants or wireless microphones, or to diagnose the causes of detected hearing losses.

Device Story

Handheld screening device; integrates Otoacoustic Emission (OAE) screening, tympanometry, and pure tone audiometry. Inputs: patient response via switch (audiometry), microphone response (tympanometry/OAE), and pressure changes (tympanometry). Operation: trained personnel in medical/school settings perform tests; device uses internal DSP to process signals. Outputs: test results displayed on device; data exportable via IRDA to Windows-based software for graphing and patient ID management. Benefits: consolidates three diagnostic functions into one portable unit; enables efficient hearing loss tracking across all ages. Safety: includes watchdog timers for tone generation; pressure-limited pump; battery-powered.

Clinical Evidence

Bench testing only. Device performance verified against established ANSI standards (S3.6 for audiometry, S3.39 for tympanometry) and electrical safety standards (IEC 601-1, UL2601-1). No clinical data provided.

Technological Characteristics

Portable handheld device; rechargeable battery powered. Features miniature probe speakers and microphone. Connectivity: IRDA. Software: Windows-based for data management. Safety: Watchdog timers for tone monitoring; pressure-limited pump. Standards: ANSI S3.6 (audiometry), ANSI S3.39 (tympanometry), IEC 601-1, UL2601-1, CSA 601-1-M90, EN55011, IEC801-2/3/4.

Indications for Use

Indicated for detection and tracking of hearing loss and abnormal middle ear conditions in all patients, from premature infants through adults. Intended for use by trained personnel in medical or school settings. Not for prescribing/fitting assistive listening devices or diagnosing causes of hearing loss.

Regulatory Classification

Identification

An audiometer or automated audiometer is an electroacoustic device that produces controlled levels of test tones and signals intended for use in conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders.

# Device Description, intended Use & Effectiveness:

The Grason-Stadler Inc. model GSI 70 AudioPath™ Screener is similar to and predicated upon the Grason-Stadler Inc. model GSI 60 Otoacoustic Emissions/Screening Audiometer, the GSI 37 Auto Tymp Middle Ear Analyzer, and the GSI 17 Pure Tone Screening Audiometer. The purpose of this device is to detect as well as track hearing loss and abnormal middle ear conditions in all ages of patients (From premature infants through adults age). The instrument has a battery of testing capabilities such as Otoacoustic Emission Screening, Tympanometry, and Pure Tone Audiometry. The device is intended to be used by trained personnel in a medical or school environment. This device is not intended for use in prescribing or fitting assisstive listening devices such as hearing aids, cochlea implants or wireless microphones.

### Technological Characteristics:

See attachment "A" for a comparison of the GSI 70 AudioPath™ Screener to the predicate device.

### Safety:

The GSI 70 AudioPath™ Screener is designed to provide electrical safety to the patient as well as the user. The system is designed to meet the following standards related to electrical safety: IEC 601-1, UL2601, and CSA 601-1-M90. To prevent excessive tone levels within the ear the system is designed with watchdog timers that monitor the system and disable the tone generation when disparity is detected. Also, the speakers that are used within the probes are

{1}------------------------------------------------

incapable of producing enough decibels to permanently damage the ear. The pump for the tympanometry function has been designed such that the volume of the pump is incapable of producing a pressure that would exceed the safe level as specified within ANSI S3.39.

The system will also be certified to the following standards:

| EMI EN55011 | Group 1 Class B requirements (medical equipment, conducted and radiated<br>emissions). |
|-------------|-------------------------------------------------------------------------------------------------|
| IEC801-2 | ESD Susceptibility. |
| IEC801-3 | Radiated Electromagnetic Field Susceptibility. |
| IEC801-4 | Conducted Susceptibility to Line Transients. |
| CE Mark | Conforms with provisions of European Council Directive 93/42/EEC concerning<br>medical devices. |

#### Summary of Effectiveness:

The GSI 70 AudioPath™ Screener is a consolidation of three current audiological products into one portable instrument making it equivalent or better in effectiveness for the detection and tracking of hearing loss and abnormal middle ear conditions in all ages of patients (from premature infants through adults).
