1.2 Intended use
The AD629 audiometer is designed to be a device for diagnosing 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 diagnosing of hearing loss using this kind of diagnostic
audiometer depends on the interaction with the patient. However, for patients not responding well
possibilities of various tests allow the tester to have at least some evaluative result. Thus, a “normal hearing”
result should not allow for ignoring other contra indications in this case. A full audiologic evaluation should be
administered if concerns about hearing sensitivity persist.
The AD629 audiometer is intended to be used by an audiologist, hearing healthcare professional or trained
technician in an extremely quiet environment according to the ISO standard 8253-1. This instrument is
intended for all patient groups regarding sex, age and health.Careful handling of the instrument whenever in
contact with a patient should be of high priority. Calm and stable positioning while testing is preferred for
optimal accuracy.

3.1 Back panel external connections – standard accessories
The back panel contains all the rest of the main connectors (sockets):
Special notes:
•In addition to the standard DD45 headset, four other air conduction transducers may be used
(they all connect to specific outputs on the AD629):
•HDA300: High Frequency requires a HF headset
•CIR33 for insert masking: Insert phone CIR33 for insert masking has a limited sound
quality, making it only adequate for masking noise presentation.
•EAR-Tone 3A or 5A general purpose insert phone: Insert headphone EAR-Tone 3A or
5A are high quality transducers that may be used instead of the DD45/TDH39. It
improves cross hearing from the normal approximately 40dB of the TDH39 to
approximately 70dB. Masking as well as avoiding over-masking is thus easier with this
type of headphone.
•IP30 insert phone is the standard insert phone with same properties as EAR-Tone 3A
•The LAN connection is currently not used for any application (only internally in production)
•Mic 2: Please refer to the section about Patient Communication (Talk Forward and Talk Back)
•CD-input: It is required that any attached CD-player has a linear frequency response in order to
comply with the requirements of IEC 60645-2
•USB connections is used for:
•PC connection to Diagnostic Suite (the large USB connector)
•Direct print
•PC-keyboard (for entering client names)
