Digital Calibration Verification Built-in

 audiometer calibration verification

Calibration verification just got easier


Daily calibration verification checks are now quicker and easier than your morning tea.

X-check (cross-check) is a digital calibration verification tool designed as an add-on for all KUDUwave™  devices.
It enables accurate calibration verification (within 5dB) to objectively ensure the precision of your results.

Annual exhaustive calibration of audiometers is common best practice in most standards of audiometry.
With some even requiring quarterly calibration intervals in occupational health.


But what happens between calibration intervals?

Biological calibration checks are best practice as stipulated in most standards, although not everyone does them. These calibration checks are intended to ensure the accuracy of your device on a daily basis before continuing with testing and ensure that your results are as accurate as possible, but, how many clinicians or occupational health practitioners actually perform these standard practice tests?

Why biological calibration isn't good enough

Biological tests are subjective and are done within an effective 20dB allowance. This makes them fundamentally unreliable and inaccurate as even a 10dB variation could make all the difference.
As we all know, even a common cold can affect your hearing levels, even before you are acutely aware that you are ill. These small variations contribute to the lack of accuracy of the results of a biological test.
With such broad allowances and subjectivity, one cannot solely rely on this form of verification.

Accuracy is not the only issue. They are also time-consuming and in a world where time is rare, these checks are skipped in favour of simply getting on with the day. Skipping this vital part of the daily process has severe quality, cost, ethical and legal risk implications.

That is why we developed X-check.
A digital calibration verification tool that takes just 30 seconds to run. Subjective testing is replaced with digital accuracy that relies on scientific methodology to perform an objective check of your equipment.
With X-check you not only save valuable time but you are also able to ensure that you stay compliant with the relevant standards and follow best practice.
