Ambient Noise Monitoring Values
Now you can see exactly if the ambient noise levels affected your test results.
During an audiometry assessment, the KUDUwave monitors ambient noise levels in the test environment and prompts the clinician if it is too noisy for testing. Furthermore, the KUDUwave monitors and measures the level of noise that is in the ear canal during assessment. It is important to recognize that the noise levels may be artificially elevating the hearing thresholds of the patient.
Where can you find these Readings?
The ambient noise values are recorded on the KUDUwave audiogram in order for the clinician or the audiogram viewer to scrutinize how compliant the ambient noise levels were during audiometry assessment. The noise in the ear canal is indicated in grey text below the threshold reading.
How do I know the environment was too loud?
In order to ensure true threshold readings, the environment noise must not exceed the level of intensity of the tone being presented to the patient. In other words, the noise in ear canal (value is coloured in grey below the threshold reading) should not be higher than 10 dB, if a patient was tested down to 0 dB.
The KUDUwave software takes all of these details into consideration. On the audiogram, ‘noise values’ will be highlighted in orange if the environment noise is above, or louder than, the pure tone that was presented at that frequency. Below is an example of how noise levels can interfere with the results.
