Questions and Answers

What does masking refer to in the context of hearing tests?

Using different wavelengths to assess sound perception
Testing the sensitivity of the auditory nerve
Enhancing the loudness of a signal in the ear
Making a tone inaudible due to surrounding noise (correct)

In clinical masking, where is the noise delivered?

To both ears simultaneously
To the external environment
Only to the test ear
To the non-test ear (correct)

Which of the following statements is true regarding the application of clinical masking?

Noise must be presented in the test ear for accurate measurement.
Masking noise is delivered to the non-test ear for effective hearing assessment. (correct)
The test signal can only be assessed through bone-conduction.
The same type of noise is used regardless of the type of test signal.

Flashcards

Masking

Making a tone inaudible by introducing noise in the same ear.

Clinical Masking

Clinical masking is a technique used to prevent sound from traveling to the non-tested ear, ensuring only the tested ear is being evaluated.

Nontest Ear (NTE)

The ear that's not being tested.

Test Ear (TE)

The ear that's being tested.

Masking Noise Delivery

Noise is delivered to the NTE through air conduction, regardless of whether the TE is tested by air or bone conduction.

Study Notes

Masking Definition

Masking renders a sound inaudible due to a simultaneous noise in the same ear.
Masking the right ear involves a noise presented to that ear, preventing a tone from being heard.

Clinical Masking

Clinical masking reduces cross-hearing during hearing tests.
Masking noise is presented to the non-test ear (NTE).
The test signal is presented to the test ear (TE).
The noise is delivered to the NTE via air conduction, regardless of the testing method (air or bone conduction) for the TE.

Masking Noise Considerations

The selection of appropriate masking noise depends on the signal being tested.
This detail is discussed in a later section.
The notes presume appropriate masking noise is used.
