Interpretation of Test Understand

Understand the test measures in a specific way of understanding the presence of noise or noise. The test is based on the fact that normal hearing is able to have almost 100% of the words to understand, even if the background noise as loud as the voice level. Hence, people talking loudly at a party or a meeting. In fact, the speaker's voice intensity change (even making loud) to the overall loudness level of the environment to his hearers to enable him to understand.

Understand who at a test-not all words can be understood as the ambient noise as loud as the voice, intelligibility suffers loss. This intelligibility loss is relevant if more than 50%.
