Today’s Hearing Aids Are Programmed Specifically to the User’s Hearing Loss
The first electronic hearing aids were designed to fit a certain range of hearing–moderate, high, and super power hearing aids would fit moderate, severe and profound hearing losses respectively. Unfortunately, more often than not the person would have way too many low frequencies amplified. This made the hearing aids too loud in noise and the user’s voice sounded like their head was in a barrel. The only thing a Hearing Aid Specialist could do was adjust a trimpot (screw) on the hearing aid, (if it had one) to cut the low frequencies. Increasing and decreasing the air flow vent on the custom hearing aids or earmolds would also help modify the sound of one’s voice. It was the “manually adjust and try” method. Half of the time the hearing aids were returned or they were often left in the drawers.
Fortunately the digital hearing aids of today are are tiny sound processing computers that can be programmed specifically to one’s hearing loss. The more sophisticated the hearing aid circuit the more precise the programming is and the better it performs in noise. When the hearing aids are hooked up to the computer wirelessly through Bluetooth or via cords and Noah Link. The initial fit of the manufacturer’s software will adjust the gain and output of the hearing aids based upon the hearing test results. Many hearing aids will actually store the audiogram and the settings in
the hearing aid. This is a real advantage when the user moves away or is vacationing and needs the hearing aids service or adjusted.
When one has a decline in his or her hearing, it is quite simple to hook the hearing aids up to the computer to reprogram the hearing aids to the user’s current hearing loss. Most hearing aids are designed to have extra gain and output available if necessary. At Welsch Hearing Aid Company we program the hearing aids while they are in the ear so the patient can hear the changes real time.
If a person donates their used behind-the-ear, or receiver-in-the-ear hearing aids for someone else to use, there is a good chance that it can be reprogrammed for a different hearing loss. At Welsch Hearing Aid Company we believe in recycling used hearing aids. They should be put to good use. If we can’t reprogram the aids or they no longer function properly, then we will donate them to the Lion’s Club and they will in turn get money for the hearing aid parts to help them buy new hearing aids for those that cannot afford them.
