Automatic Impedance Audiometer Introduced by Teledyne Avionics
Teledyne Avionics, designer and manufacturer of medical instrumentation, has introduced the TA-7B, an automatic impedance audiometer for school, pediatrie, and general medical practice hearing screening programs.
A feature of the TA-7B audiometer is that it enables medical personnel to perform tympanometry in 1 second and acoustic reflex testing in less than 5 seconds. This allows virtually any person to be tested successfully - even very young subjects.
The TA-7B can interface directly with any computer through a built-in RS-232 serial port, offering almost unlimited data acquisition, storage, and diagnostic capabilities. This full-range air conduction audiometer can be used to obtain thresholds or screening data from 250 to 8000 Hz. Initial dB level is selectable at the factory
The operator can switch easily between screens to view data. The TA-7B stores right and left impedance and audiometrie data, indicates test results immediately through LCD readout, and prints all data in memory, quickly and quietly, at the push of a button.

Multi-Channel Hearing Implant for Young Children
In October 1986, the FDA granted an Investigational Device Exemption for the first clinical trials (with profoundly deaf 2- to 9-yearold children) of a multichannel cochlear device that may make speech recognition possible. It is hoped that this Nucleus-22 channel device will make it possible for youngsters who cannot be helped by hearing aids to recognize speech and acquire language skills.
Potentially, multichannel cochlear implants in young children exceed even the results achieved with postlingually deaf adults (deafness occurring after language skills are developed). According to a paper written by Dr. Gerald E. Loeb of the National Institutes of Health, "the more plastic [flexible] nervous systems of children might learn to cope better with the inevitable distortion produced by electrical stimulation."
Multichannel cochlear implants have been successful in adults and in adolescents ages 10 to 17. Patients with the Nucleus-22 have significantly improved ability to recognize speech with lipreading, and about 43% of implant recipients can also recognize some speech without lipreading, even making telephone conversations possible.
The Mini-22 also incorporates a magnet into the external transmitter because young children find elaborate headsets unwieldy and cumbersome.
The Nucleus-22 is the only multichannel cochlear implant with FDA approval for marketing in the United States. American Speech Language Hearing Association (ASHA) recommends the use of multichannel implants, rather than the single-channel 3M/House device, in controlled clinical trials with children.
