1) Improper adjustment of hearing range. Fitting professionals are mainly determined according to the wearer's own audition feeling. At that time, the audition was influenced by many subjective and objective factors, and the audition feeling was not necessarily accurate, especially for beginners. The result of debugging in this way may not be applicable in another environment, and the phenomenon of "ear tightness" will naturally occur.
2) The degree of hearing loss has changed. Changes in age and physique will lead to changes in hearing, which will make hearing AIDS feel "boring".
3) Hearing aid channel sound transmission disorder. Earplugs are blocked by earwax (right elbow) and blocked by water vapor, which hinders sound transmission, resulting in low sound and "ear tightness". This is also the most common and common reason for "ear tightness".
4) hearing aid soft earplugs are aging. Soft earplugs are made of plastic and will age (stiff) if used for a long time. If they are inserted too tightly in the ear canal, they will feel "stuffy".
5) The nose is not smooth. The nasal cavity is blocked, and the eustachian tube is not completely closed due to colds and rhinitis, resulting in uneven pressure inside the eardrum (middle ear) and outside the eardrum (outer ear) and invagination. At this time, wearing a hearing aid will feel "stuffy ears."
6) Lack of "breathability". If the hearing aid wearer wears it for more than ten hours from morning till night, the earplug will be closed for a long time and not opened in the middle, and the ear mold will also sag.
After wearing a hearing aid, "ear tightness" will make people feel very uncomfortable. For "deafness", it can be completely solved. There are usually the following methods to solve "ear tightness".
1. Select the ear opening option and readjust the audio and gain of the hearing aid until the "ear tightness" is eliminated or alleviated.
If the power of the hearing aid is too low, you need to change it to a high power one.
3. If the soft earplugs are not smooth, they can be wiped clean with cotton; If there is water vapor in the ear seat, the joint between the plastic conduit and the horn mouth can be disassembled and cleaned with a cotton swab.
4, timely replacement of aging soft earplugs, and the size should be suitable for your ear canal.
Deaf patients must pay attention to prevent the occurrence of respiratory diseases in their lives.
6, in the process of wearing a hearing aid, let the hearing aid breathe normally.
7. Buy qualified, regular and high-quality hearing aid batteries. Buying a battery must depend on the date of production of the battery. In general, if the battery is stored for more than half a year, the effect will be worse, and the storage environment of the battery will also affect its life. This method can be used to judge whether the battery is normal: if there are spots on the positive and negative poles of the battery, or the battery with protrusions on the bottom is not optional.
