GSI 18
Screening Audiometer
Flexible and efficient, the GSI 18™ is a portable audiometer that travels with you. The GSI 18 is a great choice for clinicians who conduct audiometric testing in multiple environments. The audiometer provides three stimulus options and a choice between two transducers to accommodate all screening environments. In a school screening environment, it’s easier for the operator to test hearing on a distracted child with a more interesting signal. In an industrial screening environment, the operator can present a signal that allows the patient to distinguish the signal from “ringing” in the ear.

Frequently Asked Questions
Can the GSI 18 be operated with batteries?
Conducting a hearing test does not depend on a power source. While the device can operate on AC power, you can get up to 10 full hours of testing using five AA batteries. This is ideal when out in the field, conducting testing at health fairs, and during home visits.
When is it best to use the patient response button?
This is a great way to conduct screening audiometry with all patient types. A patient response button helps testers concentrate on results, instead of visual cues from the patient.
Do all the accessories and device fit in a compact case?
Yes, the GSI 18 is easy to take from site to site when conducting screening visits. This portable audiometer has everything needed for testing and users can easily carry it in a convenient case.
What options do you have for a noisier environment?
Users can switch between using headphones and insert phones with the GSI 18 depending on the environment. Using insert phones in noisy school and industrial screening environments can help control noise and achieve more accurate results.
What frequency and intensity range is available for air conduction testing?
The GSI 18 allows the operator to test frequencies from 125 to 8000 Hz at intensities from 0 to 100 dB, unlike other screeners. This allows the operator to conduct hearing screenings on all levels of hearing loss.

Multiple Routes to Results
The GSI 18 is a logical choice for every screening environment. Full frequency and intensity range allows for simple screening or more advanced air conduction threshold evaluations. The patient response button, stimulus options, and choice of two transducers make it ideal for screening varied patient populations.
Portability Provides Options
Take advantage of the features on the GSI 18 while testing remotely. Weighing in at 2.5 pounds, this audiometer is perfect for traveling from site to site.
Do not limit your testing by having access to a power source. Choose from AC or battery operation. By installing five AA batteries, you can conduct 10 hours of testing.
Switch Freely
Easily switch between supra-aural and insert headphones as the environment dictates. The GSI 18 audiometer holds calibration for two air conduction transducers. Comply with infection control policies with disposable insert eartips.
Full Frequency and Decibel Range
Users can easily get full air conduction results. This covers a frequency range of 125 to 8000 Hz and a decibel range of 0 to 100 dB.
