Hearing Aid Gain â Which One? The input to a hearing aid is subtracted from the output. The result is the gain of the instrument. The use and understanding of hearing aid gain is common among hearing professionals. It is essentially the difference between the level of a sound into a hearing aid versus the amplified level of what comes out of the hearing aid (Figure 1).

- The in situ gain of a hearing aid is measured with the hearing aid in place in the ear. Intensity: The loudness or volume of a sound. In-The-Canal (ITC) Hearing Aid: Smaller than an ITE hearing aid, it usually fills up a portion of the ear canal and a small portion of the outer ear. A mini-canal attempts to make the hearing aid even smaller by using a smaller battery.

History of hearing aids The first hearing aid was created in the 17th century. The movement toward modern hearing aids began with the creation of the telephone, and the first electric hearing aid was created in 1898. By the late 20th century, the digital hearing aid was distributed to the public commercially.Some of the first hearing aids were external hearing aids.elephones were able to control the loudness, frequency, and distortion of sounds. These abilities were used in the creation of the hearing aid. The first electric hearing aid, called the Akouphone, was created by Miller Reese Hutchison in 1898. It used a carbon transmitter, so that the hearing aid could be portable.
