The cold current has hit these days and the temperature has dropped! Hearing has a reminder: In addition to the body should pay attention to cold and warm, the hearing aids of the ear damage should also be careful of the temperature difference between indoor and outdoor, and need to care for the hearing aid, in order to give full play to its effect and extend the service life! In winter, due to the large temperature difference between indoor and outdoor, the moist hot air in the ear canal enters the cold hearing aid receiver, producing condensed water. If the condensed water cannot be removed in time, it will be less in the receiver.
If the condensed water is in a small collection in the receiver, it will cause the receiver to “catch” when it is concentrated to a certain amount. The symptoms of the cold are manifested by the sound of the hearing aid being light, the sound is boring, the noise/distortion, sometimes the absence, the silence, etc. Sound holes, which can also seriously erode the receiver components.
Especially in areas where the winter is cold but there is no heating, the custom machine has a large temperature difference inside and outside the ear canal, which is more likely to produce condensed water; even in the colder areas of winter, even if there is heating supply, due to more outdoor activities, It is also easy to produce condensed water.
Customized hearing aids with larger shapes, especially for ear-hounded hearing aids, are more likely to generate condensate in the receiver due to their large external air contact area and large internal receiver volume. When the above conditions are met, condensed water will be generated inside for a few days. If it is not treated, the hearing aid will usually malfunction for more than half a month, such as the sound is boring and silent. The most effective way to prevent condensation inside the custom machine during the winter is to:
When the 1 and hearing aids are not in use, remove the battery and put it in a closed dry box.
2, in the cold or wet season, insist on using electronic nursing treasure to dry the hearing aid every day.
11 hours per night from 4 months to 6 months of the following year; 3 hours per night for other times; if the moisture is obvious, the drying time should be extended until it can be used normally. Open the battery door when dry (do not dry the battery). It is most effective to use the electronic care treasure to dry the water inside the machine; using a dry box can prevent the machine from getting wet, but the moisture removal effect is not obvious.
3, before washing your face, bathing, swimming, washing your hair, etc., please remove the hearing aid; if there is water in the ear canal after any activity, be sure to use a cotton swab and other tools to dry the water in the ear canal before wearing the hearing aid. It is easy to cause the hearing aid to get wet.
If you find that the hearing aid has been light, or the sound is boring, or noise/distortion, the hearing aid may have accumulated condensation. At this time, it is necessary to extend the drying time of the electronic nursing treasure, or to hand over the hearing aid to the hearing aid service center for maintenance and treatment as soon as possible!
