• To enhance the sound quality

• To prevent detection of the pure tone by the non-test ear

• To increase the volume of the test ear

• To decrease the volume of the non-test ear

What should be done if there is a possibility that a-c thresholds at certain frequencies are not the true thresholds?

• They should be masked or marked accordingly.

• They should be ignored.

• They should be retested immediately.

• They should be considered as true thresholds.

What is the purpose of the instructions for masking?

• To guide the participant on how to respond during the test.

• To explain the technical details of the test.

• To provide background information on audiometry.

• To describe the equipment used in the test.

What should be done if the b-c threshold of one ear is more acute by 55 dB or more?

• Masking is needed.

• Ignore the result.

• Consider the test complete.

• Retest the same ear.

What should the subject do if the sounds become uncomfortably loud?

• Ignore the sounds

• Press the button
