The power of the device is to enhance the sound and to enhance the sound quality and purity. The apparatus should help the person with hearing deafness to hear the sounds and the sounds.
The alarms are transformed according to the sound signal alignment: analog – transforming the sound to eclipse and then enhance
Digital – Enhanced digital signals for signals.
Both types of devices can be one-channel or multichannel. The analog is usually the same, most digital – multichannel.
The new generation of the devices belongs to no extra-sized earpieces, in which the sound signals are running at high speed continuously in all frequency ranges that require significant computing power.
According to placement on the human body, the earpieces are classified as follows:
Kursiisha (ITE, ITC, CIC)
Implantable and bone conduction (BAHA – Cochlear, Sound Bridge – MED_EL, Carina – Otologics) and more.
For all types of alcoholics, except for implantable and bone conduits, the ear inscription is essential. Its functions include: sound cameras – sound transfer from the drum apparatus to the blanket. Fixation – fixing the earpiece of the patient’s ear or back of the patient. Correction – Correction of sounding sound. An incorrectly made tab can become a source of acoustic distortion and the sound quality of the sound device is vulnerable. Sound insulation – Avoiding the feedback of the hearing device, stencils. This function is especially important for stronger earpieces. The sound isolation depends on the quality of the “shutter” of the tab and the tone of the tab: the more tight the tape, the longer it is, and the more ventilated channel, the more it is the reliable external sound pipe isolation. But such inserts are often discomfortable due to the occlusion (unpleasant sound). In order to eliminate it, the ventilation channels are made.
Another important requirement that will be inserted is – it should not be irritated and disturb the external bowel pipe skin.
Alcohol inserts can be made from different materials. Today there are about 15 species of cool and soft materials (starting from standard transparent materials, with colorful patterned plastics) that have different functions. Currently, it is mainly used for antialergic materials that do not cause irritation of the skin. The insertion may be covered with antialeric spots, silver, gold, platinum, titanium or synthetic glass. Covering the metallic not only removes allergies, but also helps in removing heat from the external bowl. This is important if the patient is suffering from excessive sweating of the pipe tube, causing inflammatory reactions.
According to the type of material, ear inserts are divided into several types:
Selecting the shape of the ear tab is dependent on the power and model of the current earpiece, the shape of the tube and the size of the audiogram. In the case of lower hearing, open and skinny tabs are recommended. Important hearing loss, which requires the use of a powerful apparatus, is a massive supplement.
Patient users complain about various problems, including the ear tap. Acoustic feedback, the need to eliminate stencil need to tightly insert the tap into a drinking pipe causing friction and violates ventilation. Direct handling of the sound on the tablet’s app does not exclude the ear sink as a natural resonator from a sound bandwidth that causes the unpleasant sound of its own sound. In some cases, these problems are solved at different places of the ear insertion – using ventilation channels. Their layout and shape operate on the characteristics of sound signals of enhanced listening devices.
Individual ear inserts are an important part of modern hearing prosthesis, and to some extent determine / determine success in selecting and adjusting the apparatus. The efficiency of the best teens may be dramatically dropped due to the incorrectly made tab.
The process of manufacturing individual ear insertion of the earpiece device is called otoplastic. This term is used in several meanings. It was first used to mark the replacement or replacement of the ear cage and external bowel tube parts in the octopus. In 1948 the term “otoplasty” was used as a synonym for “ear insertion”.
Quality production of external bowel pipe is even more difficult when making an internal hearing device than an external ear apparatus. The accuracy of the forms is especially important because if the building is a part of the ear, it is necessary to minimize it. To minimize the need to remove excess material, and add to the magnification.
All the professionals working with people with hearing loss should know how to work, how much they have a drinking app
