The technology options available to persons with hearing challenges include very sophisticated devices that can be worn at the ear and even completely in the ear. Despite the great advances in signal processing, individuals often still have difficulty hearing when there is background noise. One solution that is routinely applied in educational settings is the use of a remote microphone that is worn by the speaker. The signal from the speaker is sent wirelessly to a receiver worn by the listener. There are numerous ways the receiver can be coupled to the personal instruments worn at the ear level. In addition, several transmission methods can be used to deliver the signal to the receiver. Regardless of the transmission method, the coupling of the receiver, or the microphone arrangement, the placement of a microphone near the speaker results in an improvement in the signal-to-noise ratio and generally a significant improvement in speech recognition in noise. With the advent of many options for wireless interfaces with computers, mobile phones, and MP3 players, there is increasing acceptance of wireless technology for many individuals with hearing challenges even outside of educational settings.
