The GSI SA60 is to be used as part of an audiometric test battery. The purpose of this device is to assess the status of cochlear function by presenting an acoustic stimulus (i.e. the primary tone pair) to evoke an otoacoustic emission (i.e. the distortion product) which is measured. The GSI 60 and the GSI SA60 utilize a probe containing a microphone and two (2) independent speakers (one for each primary tone) to present the acoustic stimulus and measure for the presence of an evoked otoacoustic emission. ## Device Story The GSI SA60 DPOAE System is an otoacoustic emissions/screening audiometer used to assess cochlear function. The device utilizes a probe containing two independent speakers to present primary tone pair acoustic stimuli and a microphone to measure evoked distortion product otoacoustic emissions. The system operates in conjunction with a notebook computer, eliminating the need for a docking station required by the predicate GSI 60. It is designed for clinical use by healthcare professionals as part of an audiometric test battery. The system provides status indicators for battery and power conditions and includes safety monitoring to prevent data collection during low battery states. The output assists clinicians in evaluating cochlear status, facilitating hearing screening and diagnostic decision-making. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Class II medical instrument; probe contains two independent speakers and one microphone. Powered by internal battery or low voltage ungrounded DC power supply. Meets IEC 601-1, UL2601, CSA 601-1-M90, IEC 950, UL1950, CSA 950, and CE mark standards. EMI/EMC compliance per EN55011, IEC801-2, IEC801-3, and IEC801-4. Designed for use with a notebook computer. ## Regulatory Identification A hearing aid calibrator and analysis system is an electronic reference device intended to calibrate and assess the electroacoustic frequency and sound intensity characteristics emanating from a hearing aid, master hearing aid, group hearing aid or group auditory trainer. The device consists of an acoustic complex of known cavity volume, a sound level meter, a microphone, oscillators, frequency counters, microphone amplifiers, a distoration analyzer, a chart recorder, and a hearing aid test box. ## Special Controls *Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9. ## Predicate Devices - GSI 60 DPOAE system (K934658S1) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Schultz (603) 672-7303 **Date Summary Prepared:** January 22, 1997 **Device Name:** Classification Name - Audiometer Common/Usual Name - Otoacoustic Emissions/Screening Audiometer Proprietary Name - GSI SA60 DPOAE System **Predicate Device:** Grason-Stadler Inc. model GSI 60 DPOAE system (ref. 510(k) #K934658S1). **Device Description, intended Use & Effectiveness:** The Grason-Stadler Inc. model GSI SA60 Otoacoustic Emissions/Screening Audiometer is similar to and predicated upon the Grason-Stadler Inc. model GSI 60 Otoacoustic Emissions/Screening Audiometer. The GSI SA60 is to be used as part of an audiometric test battery. The purpose of this device is to assess the status of cochlear function by presenting an acoustic stimulus (i.e. the primary tone pair) to evoke an otoacoustic emission (i.e. the distortion product) which is measured. The GSI 60 and the GSI SA60 utilize a probe containing a microphone and two (2) independent speakers (one for each primary tone) to present the acoustic stimulus and measure for the presence of an evoked otoacoustic emission. **Technological Characteristics:** See attachment "A" for a comparison of the GSI SA60 to the predicate device. **Safety:** The GSI SA60 system is designed to provide electrical safety to the patient as well as the user. The system is designed to be used with a notebook computer powered either by its internal battery or by the supplied low voltage ungrounded DC power supply. The notebook computer used with Page 9 {1} the system will be specified to meet standards pertaining to the safety of Information Technology Equipment namely: IEC 950, UL1950, CSA 950 and CE mark. The instrument portion of the system may be powered by its internal battery or by the supplied low voltage DC power supply. The instrument enclosure is also connected to protective earth (ground) when powered by the low voltage DC power supply. No other mains powered equipment will be connected to the system during patient testing. The front panel of the instrument will have status indicators that inform the user of the following conditions: 1) Battery charging, 2) low battery voltage, and 3) power applied. The battery charger status will be constantly monitored and the instrument will not collect data when the battery charge is too low to reliably operate the instrument. The system is designed to meet the following standards related to electrical safety: IEC 601-1, UL2601, and CSA 601-1-M90. A preliminary design review was conducted with a competent test laboratory and the design will meet requirements for electrical safety of an IEC 601-1 class 1, type B medical instrument. The system will also be certified to the following standards: | EMI EN55011 | Group 1 Class B requirements (medical equipment, conducted and radiated emissions). | | --- | --- | | IEC801-2 | ESD Susceptibility. | | IEC801-3 | Radiated Electromagnetic Field Susceptibility. | | IEC801-4 | Conducted Susceptibility to Line Transients. | | CE Mark | Conforms with provisions of 89/336/EEC Electromagnetic Compatibility Directive. | ## Summary of Effectiveness: The GSI SA60 is an extension of the current GSI 60 system and operates in the same manner. The GSI SA60 allows the use of the system with a notebook computer without the need for a docking station which is required for the GSI 60 (See attachment “A” Chart of Predicate Device Comparison). The GSI SA60 is therefore more portable than the GSI 60 making it equivalent or better in effectiveness for the testing of cochlear function.
