Abstract

The invention is a new portable equalizer with several audio inputs and one audio output, which separates the incoming audio signals into various predetermined frequency bands in the range of audible frequencies, emphasizes or attenuates each frequency band as set by the user according to his/her hearing deficiencies, mixes the emphasized or attenuated frequency bands and conveys them to the audio output. It can be provided with a specific input for the telephone connection instead of the handset. Thanks to this new equipment, even the persons with partial hearing deficiencies will be able to hear completely, it is possible to define the gain or the attenuation for the various frequency bands, it is possible to adjust the general volume of the equalizer, anyone who has hearing deficiencies can carry out a personalized adjustment of the operation of the new equalizer according to his/her own specific needs. The device may feature analogic or digital technology, even with the use of DSP (digital signal processor) technology.
