1) PREDELIVERY CHECK

1. You sanitize your hand first and handle the hearing aid with the sanitizing cloth, and do the exact action with the statement as below:

In our office, we wash our hands before handling the hearing aids. We also handle the hearing aids with a sanitizing cloth. The serial number, size, model, specification and color will be checked against the patient’s order form and patient’s record.

2. I do the following and state:

The battery is checked in the battery tester. If the battery is not in good condition, I will replace it with a fresh battery. The battery door, battery contact point, microphone, receiver, vent, ear mold, tubing, ear mold type and all moveable parts are checked and inspected. Battery door swings well. Battery contact is intact. No wax is in the microphone and receiver. The ear mold and tube are intact.

 I rub the hearing aid with my hands and the soft part of my arm to check for scratchy surfaces. I also run a hearing test box to check that the factory sent the correct hearing aid.

2) LISTENING CHECK

3. OPEN AND CLOSE the battery door 10 TIMES.
4. Turn the VOLUME UP AND DOWN 10 TIMES.
5. LISTEN WITH A STETHOSCOPE.
6. Move the MTO switches UP AND DOWN 10 TIMES.

The volume control and taper are checked using a stethoscope. One, two, and three settings. Testing One, Two, Three. There are no dead spots on the volume control. During the listening check, I check the quality of sound, feedback and noise. I check the MTO Switches and make sure all switches are working properly.

3) ADJUSTMENT OF CONTROL

This hearing aid is checked against the audiogram, MCL, and UCL. Then the pots are adjusted accordingly. In our office, we also use a real ear measurement to help us with adjustments and verification. After pre-delivery inspection, I will place the hearing aid in a clean container and call the patient.
