Assistive Listening & Compliance

The introduction of AS1428.5 has set a new high in providing the most effective listening outcome for the hearing impaired.


The concept of installing any loop system without the proper confirmation of performance capability is now in the past.

So much so that today it is necessary to verify compliance by providing a signed commissioning document, confirming that your loop installation is, in fact, compliant and meets test parameters as required in tender specifications.

There is no doubt that, as the field of assistive listening installation expands... and it will, you are goingto need the right test equipment to meet this very specific requirement.

Humantechnik Proloop FSM plus (A-4292-0) is the answer.

The PROLOOP FSMplus is a measuring device that measures the magnetic field strength of induction loop systems according to IEC 60118-4:006.

The device delivers reliable RMS values on the output level, response frequency, AGC function (Automatic Gain Control), distortion and background noise in the induction looped tested.

In addition, it enables the user to make an acoustic evaluation of the sound using signal reproduction via earphones
