Deaf aid is another name used for hearing aid. These are devices used by deaf people for improving hearing ability. In many countries, they fall under mechanical devices and are subject to regulation as such. Hearing aids have evolved with time from being simple sound amplifying gadgets to devices of artificial intelligence that are simply computerized electroacoustic systems.
Modern devices make sounds more comfortable and intelligible because they are computerized electroacoustic systems. They have sound processing abilities that allow them to cancel noise and wind, highlight voice, highlight spatial region, and shift frequencies. Configuration needs to be done to the gadget so as to match with the extent of loss of the ability to hear, physical features, and lifestyle of the user.
The devices need to be configured to match various aspects. The configuration is referred to as fitting and it is done by an audiologist. The quality of fitting done in the gadget often determines how beneficial the user finds it to be. It is vital to understand that deafness cannot be truly rectified by a deaf aid. The most the devices does it to increase accessibility to sound.
The efficiency of the devices is minimized by two major factors. The first factor is the loss in brain cells responsible for processing sound. This loss occurs when the primary auditory cortex is not stimulated regularly due to lack of sound waves transmitted to it. This problem worsens as the extent of deafness increases. The second factor is the damage of hair cells in the inner ear, resulting in sensorineural hearing loss. This makes it hard to discriminate sounds.
Evaluation of how effective a gadget is in compensating for hearing loss is done using various methods. Among the evaluation methods currently in use is audiometry. This evaluation is undertaken under laboratory conditions to measure the level of hearing in a person. The method tries to mimic the conditions in a real world to the highest degree. However, regardless of the mimicry, patient experience is still very different.
The representation of the outcome of a device can be done using three key dimensions. The dimensions are hearing aid usage, aided speech recognition, and satisfaction. A technique called real ear measurement can be used to gauge the correctness of adjustments made to the device. A silicone probe tube microphone is employed in this method to assess characteristics of amplification the device does near the eardrum.
Various kinds of these gadgets are available on the market today. Various aspects of the various models vary, including circuitry, power, and size. Some common contemporary types include receiver in the canal aid, behind the ear aid, body worn aid, on-the-ear aid, and BTE cross system. Others are earmolds, open-fit gadgets, disosable deaf aid, BTE Bi cross system, stethoscope deaf aids, bone anchored gadgets, extended wear gadgets, and invisible in canal deaf aid.
Button cell zinc-air batteries are the most commonly used battering in modern devices. There are five major standards of these batteries. Mercury batteries were common in older models of the device. Other manufacturers of modern devices also use long-life disposable or rechargeable batteries.
