There are two basic approaches to assistive technology for auditory impairments: augmentation of existing pathways and use of alternative pathways. Augmentation involves amplifying sounds to improve reception of certain frequencies for those who are hard of hearing. Alternative pathways include tactile substitution, where sounds are felt through touch, and visual substitution, using displays to represent sounds. Examples of aids discussed include hearing aids, cochlear implants, visual alarms, and computerized speech and text.

- This slide shows several tools that children with hearing impairments and other learning disabilities can use to help them participate more fully in educational activities. Pictured are amplification systems with hand held microphones to amplify a communication partner’s voice and other systems which specifically amplify the teacher’s voice and direct it into the student’s earpiece, headphones or hearing aid. Also pictured is a classroom amplification system can benefit all of the students in a classroom by amplifying the teachers voice and projecting it through speakers placed around the classroom. In addition, there are adaptations that can allow students access to classroom materials and information via multimedia, telecommunication and interpretation services. Objects pictured on this slide include: On the left, Auditory Trainer by Phonic Ear On the right, Sound Wizard by HITEC Speechmaker by Williams Sound Portable Wireless amplification system by LightSPEED Technologies
