MA 25 Operating Manual

2. Description
The MA 25/MA 25e screening audiometer is designed to be a device for screening for hearing loss. Output and
specificity of this type of device are based on the test characteristics defined by the user, and may vary depending
on environmental and operating conditions. The screening for hearing loss using this kind of audiometer depends
on the interaction with the patient. As with any type of hearing screening, a “pass” result should not overrule any
additional concerns regarding hearing ability. A full audiologic evaluation should be administered if concerns about
hearing sensitivity persist.
The MA 25/MA 25e audiometer is intended to be used by an audiologist, hearing healthcare professionals, or
trained technicians in a quiet environment.
2.1. Extended Function
The MA25e extends the MA25 functionalities with the following three extra features:
• The MA25e can communicate with a computer.
• In addition to traditional manual testing, the MA25e incorporates a Hughson-Westlake patient controlled automatic
threshold test complying with ISO 8253. When the test is completed the results are easily recalled from the internal memory
of the MA25e.
• Talk Forward function that makes the MA25e easy to work with particularly in sound booth installations.
