Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Electroacoustic devices of the individual use with software controllable parameters A.L. GALIEV, SH.R. AKHMETOV, A.V. ORLOV, N.I. JUMAGULOV The paper deals with the construction features of subminiature electroacoustic devices for individual use. It is noted that the reliability of the miniature devices is no longer determined by the reliability of the circuit solution, i.e. an electronic amplifier, converters, etc., but by the design of miniature and superminiature control element. Setting the characteristics and parameters of modern miniature electroacoustic devices should be carried out in special laboratories, taking into account the individual specifi city of each hearing aid consumer`s auditory system. The authors of this paper propose an amplifier circuit for a miniature electroacoustic system with five software-controlled (adjustable) basic parameters. Keywords: software control, register structure, hearing aid, comparator, integrator. DOI: 10.25791/pribor.10.2019.947 Contacts: - Pp. 36-40.
