Masking

Principles of Masking and Interaural Attenuation

QuestionAnswer
Another name for interaural attenuation is? Transcranial transmission loss
Where the acuity of the ears is very different, there is a possibility that... The NTE hears the sounds at a lower dB level despite interaural attenuation
Test ear Ear upon which the audiogram is being determined
Crossover Where the intensity of the test tone exceed the IA to be present in the test ear
Cross Hearing Where the intensity of the test tone exceeds the IA and the bone conduction threshold for the NTE and is detected in the NTE.
Why do we use 40dB when the interaural attenuation could be much higher, e.g. 80dB attenuation To ensure all subjects receive the right amount of attenuation as those with higher IA will not be affected by masking.
What will the audiogram show if cross hearing is occurring? Worst hearing ear will show a shadow of the better hearing ear
What is masking? The use of noise to prevent detection of the test tone in the NTE
Effective masking noise is calibrated to ... above test tone 4-6dB
How does masking work? Masking noise has test frequency at it's centrepoint - brain does not respond to presence of test tone
Equation for whether cross hearing occurs Intensity of test tone - IA > bone conduction threshold in NTE
Effective masking The intensity of masking noise required to mask a test tone of the 'same' intensity

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
