1. How changes the battery?
The seal of the battery should be removed and placed with the positive side up in the compartment of the portapilas or rubs with the pole + without hesitation.

2. What is the duration of the batteries?
The duration of the battery depends on various factors: for Example. The adjustments of the hearing aid , the quality of hours used, the environments in which used , and the volume in which the hearing aid is set at.

3. What tests can be done to verify the operation of the hearing aid before needing technical service?
If the hearing aid stops functioning, some tests: that can be done to verify the load of the battery or to replace it with a new one, To verify the entrance of the microphone (orifice that is found in the cover portapilas in the model CIC and intra-channel) and exit the headphone (final orifice at the outset in the same models that has a small filter anti-cerumen). If the battery is verified and the filter, is clean and the hearing aid is not set in motion, technical service is then need.

In the model retro-auriculars, to verify the battery or to change it and to verify that be free the exit of sound in the tip of the auricular mold and in the elbow of the apparatus. In the event that the hearing aid continue with the problem should resort to the technical service.

4. How to clean the hearing aid?
To do a correct cleaning of the hearing aid, should consult with its fonoaudióloga and also to read the instruction manual where clear explanations and images illustrated are for a better comprehension.

5. Why do they serve one of the elements of cleaning?
With new hearing aid comes a cleaning kit included is needle to clean the ventilation (this is a parallel where the sound exits). The kit also has a flannel to clean the hearing aid outside, a magnet, that will serve him to place or also has the battery of the earphone and a brush to be able to clean the hearing aid in the zone of the cover for the batteries.

6. Each as much as time they change the filters anti wax?
The filter anti-wax of the CIC and intra-channels should be controlled and to clean with the needle mentioned every day is important to change the filters to guard against wax build up. This depends on the form of the conduit and the skin of each person.

7. Why one must change the filter?
Ear wax filter should be change so that the wax that is found in it penetrate does not the hearing aid and damage the performance of the hearing aid, the damage to the hearing aid can decrease .The volume, distortion in the reception of the sound and the total dumbness of the apparatus. The headphone does not need repair, only change.

8. How should they wash the molds?
The molds or shell of CIC or intra-canal cannot be washed. To wash the mold of a retro auricular, should separate it of the earphone (to separate it should take the elbow of the earphone and the pipe of connection of the mold and to throw), then to place alone the mold in water to room temperature and neuter soap (without perfume neither alcohol neither detergent) for damage not the material of the mold, washes it among its hands and leaves to pass the water by the pipe.

When it withdraws should dry it outside with a cloth and the pipe inspiring air with a special pear (to see elements of cleaning).

9. When should change the pipe of connection?
When the pipe is becomes hard, changes color or separates from the mold does it become necessary to change without these modifications deterioration of sound quality is to be expected.

10. Each as much as should change the mold?
In case of the babies up to 9 months, you have to change the mold every 3 months. Children from 1 to 4 years, you have to change the mold every 6 or 8 months. After 5 years and adults at least once to the year.

Keep in mind if hearing aid begins to have feedback (honks), the mold modifies the original consistency or change of color, this would dictate a change of mold is necessary.

11. Why there, feedback or constant honk?
Feedback itself is due to a faulty mold, to a pipe of limp or punctured connection, to a plug of wax in the external auditory conduit or to a limp elbow in the hearing aid. All these motives can cause honks should be controlled and verified by the Audiologist who will resolve the problem or will direct to you it the otolaryngologist for cleaning of your ears.

12. What is a relaqueado?
The relaqueado is a bath of very fine shellac, this serves to lightly swell the wall of the shell and to avoid possible honks or sliding of the mold in the ear canal. The relaqueado does not avoid redoing a new mold, only defers it.

13. What is and why serves the ventilation?
The ventilation is a hole drilling through the length of the shell is parallel to the pipe to give greater comfort to the user depending on the auditory loss.

14. The importance of technical maintenance?
It is recommended that a technical maintenance be provided every 6 months; in this manner we can assure the maximum operation and performance of the hearing aid.

15. What differences are there between a hearing aid CIC (of deep insertion), an Intracanal and a Retro auricular?
The CIC hearing aid is inserted in the internal third of the external auditory ear canal
The hearing aid also is inserted in the Just ear canal extending remaining to the edge of the CAE.

And the retro auricular is supported in the auricular building united to the mold that maintains it and conducts the sound through the pipe of connection by the auditory conduit to the drum.

16. What differences are there is between a digital hearing aid and analog hearing aid?
The analog hearing aid receives the acoustical signals of the environment, mixed with speech and amplifies it returning it the user with characteristic but stronger volume. Its calibration is performed out with certain adjustments of tone, amplification etc. And the volume of use depends on the external potentiometer.

The digital hearing aid possesses a chip that performs 30,000 analysis per second of the sounds and the environment and speech, processing them in different channels so that the word itself is highlight above the noise environment in real-time and automatically. This process of the signal permits greater discrimination offering natural and comfortable hearing.

17. What should be done to equip a person with auditory loss?
The patient should do audiologists studies requested by the doctor and once the auditory loss is determined then be tested for the use of hearing aid.

18. What studies audiologists should carry out?
The patient should do an audiometric tonal, level of inconvenience, logo audiometric, and then, in the event that the problem is not of medical and/or requiring surgery. a prescribed hearing aid is recommended , a selection of earphones.

19. What is an audiometric?
The Audiometric is a study that evaluates the auditory threshold in decibels and determines the level of auditory loss for each frequency.

20. What is an auditory test for the choice of hearing aid?
Selecting a prescribed hearing aid ideal for the specific auditory loss of the patient .
