DIAGNOSTIC INTERPRETATION Consider the audiogram or other test results and answer the questions.

The noise used for pure tone masking is broadband.

The TM (tympanic membrane) vibrates most efficiently when middle ear pressure is equal to ambient pressure.

MASKING Where do you need to mask? For each ear/transducer, enter the frequencies that need to be masked without commas (e.g.: 250 500 1000). Please list frequencies from lowest to highest. If no frequencies need to be masked, write “none”.

Assume supra-aural headphones.  Right Air Conduction: Left Air Conduction: Right Bone Conduction: Left Bone Conduction: Already Masked

Behavioral Observation Audiometry (BOA) relies on operant conditioning.

The reasons 226 Hz is used as the probe frequency for tympanometry is because at 226 Hz 1 mmho = 1mL and low frequencies are stiffness controlled.
