RU156U1 - Device for compensating for hearing loss - Google Patents

Abstract

A device for compensating for hearing loss, comprising microphones, units for dividing the signal into frequency bands, including frequency band level controls, and pickups, characterized in that the units for dividing the signal into frequency bands common to all patients, including electric band filters, the inputs of which are connected to the microphone of the teacher and patients, and the outputs are connected to the signal level controllers in the frequency bands, the outputs of which are connected to a summing amplifier for each the ear canal, and the headphones of the patients are connected to the outputs of summing amplifiers.

Description

A device for compensating for hearing loss is intended for non-use in healthcare and, in particular. be used in specialized audiological centers, schools, schools, schools, and schools, and individually for the restoration of speech at / year, / Gvizhach partial hearing loss.

the device for yin78g1 "sensible loss / ha. I use the BOzach control system for the level of sound amplification in several narrow frequency bands, which are recognizable. The perceived humanity yxow frequency-ll jatiiiasoH / are well-known /.

The disadvantage of this device lies in the fact that guests P are of the high cost of the narrow-band services used for this

A device for group lessons with people, / iwe-. piece- partial hearing loss containing microphones, nodes of the gas dede in the signal to the frequency half-lives of each patient, including heg / ll-ters of the frequency band level, including a wideband amplifier & controller the level A of the lower and upper frequencies are installed at the remotes of the p-rooms. / 1 / -irototkp.

The disadvantage of this device is that for its operation it is necessary for each patient to establish an individual, node separation signal into frequency bands.

The technical task when creating a new structure is to obtain adjustable characteristics in several frequency bands individually for each paste due to the loss of power /; I ohhhh, which will reduce its cost.

The achievement of the technical result is ensured through the use of i compensation for hearing loss that contains the mic;: oh, he wanted to signal on the honest bands for: logo patents.
