Hello, and welcome to this introduction video about how to get started, using the AD528.
AD528 is a diagnostic audiometer, that is made to be easy to use, and it contains the most basic functions, that you need in audiometry.
So let's get started, having a look at the device.
Together with the device, you get a default set of transducers.
For instance the DD45, as a headphone.
You also get a patient response, so that you can have the patient respond to the sound, and see it on the device itself.
Then you get a bone conductor, so you have the opportunity to obtain bone conduction audiometry with it.
In case you want to use insert headphones instead, it is also an option to do that with the IP30 insert headphones.
They can be used as an alternative to the traditional headset, or you can use them side by side in your clinic.
So let's look at, how you can perform tone audiometry using the AD528.
The device has been built, so information is centered around channel one, and channel two, that you use during your tone audiometry.
Around channel one here, we have easy access to the patient communication, which includes the Talk Forward function, that we have here, and the Monitor function, and the Talk Back function.
The Talk Forward function allows you to talk to your patient, by holding down the Talk Forward key, so the patient can hear, what you are saying.
While you can enable the Monitor function and the Talk Back to hear, what is present in the channels and what the patient is saying to you.
Around wheel one, you have the Tone Switch, so that you an increase and decrease the level until a threshold is found, by presenting the tone to the patient, by pressing the Tone Switch.
When a threshold is found, you can store the threshold, by pressing Store.
The device will then automatically jump to the next frequency, or you can do it manually by pressing Correct, Incorrect or Frequency, Up, Down.
Once you obtain a threshold on one ear - the right ear, you can move on to the left ear, by changing the transducer in this area here, where we have the change of the transducers.
It is also from the transducer area that you change to the Bone conductor, when you want to obtain your bone conduction audiometry.
Or your Free Field, if that is needed.
Over here around wheel two, you have the masking.
The masking can be used during the session, just by turning the wheel on, - increasing the level.
Once you have masked and you are done, you can then decrease the masking level, and by turning the wheel completely counter clockwise, you turn off the masking.
In case you have a patient, that is really hard of hearing, we have the extended range, that becomes enabled, when you get a really high intensity.
You can then enable, presenting loud sounds to the patients ear.
Over here, just above channel two, you have easy access to your test screens:
Your tone, and your speech, that you use the most, where you can switch between the screens.
And also additional tests, that may be part of your test battery.
At the end of the session, you will move towards, that you may want to print your results, or save your results.
And that is done from this area here.
So you can save your results of the client, or you can print the results.
Saving is done by pressing save, where you save to the device, or to Diagnostic Suite, if you want that.
Or you can print your results by a thermal printer, an A4 printer, or by saving it to Diagnostic Suite and printing from there.
So that is a short tour on how to get started using the AD528.
