Chapter 15: Programming and Troubleshooting Hearing Instruments

To program effectively, the case history is not as important as the audiometric battery.

The style of hearing instrument must be determined by the patient.

Programming begins with the following.

Input sound pressure level is the sound at the _____.

Acoustic gain is the difference between the output SPL and the input SPL in the 2 cc coupler.

Manual gain control is another term for the _____.

A directional HI is a _____ instrument dependent on the incoming direction of sound.

SSPL 90 is the abbreviation for Saturation Sound Pressure Level for a 90 decibel _____.

The SSPL 90 is determined when the volume control is _____.

The SSPL 90 displays the _____ sounds the hearing instrument can produce across the frequency spectrum of that hearing instrument.

Most troubleshooting can be prevented by _____.

When troubleshooting, the first step you take is to _____.

To program effectively, the case history is not as important as the audiometric battery.

Check for the following when troubleshooting.

A common trouble spot is a _____.

A weak battery can lead to the following results:

If you turn the instrument onto the telecoil position, the receiver is functioning if you hear amplification. Switching to the Microphone position, if you do not hear amplification, the microphone is defective/nonfunctional.

Feedback can be due to:
