The Design of Digital Filter System used in Stimulation with Tomatis Method

Abstract

The Tomatis Method is a rehabilitation technique used in psychology, the main aim of which is stimulating the cochlea in the inner ear by filtered air-conducted and boneconducted sounds. The system of electronic filters and amplifiers used for this therapy is called the Electronic Ear. Commonly, it is an analog device, that is expensive and after a few years its functionality declines. In this paper, we introduce a digital Electronic Ear system using an STM32F4 family micro-controller and ADC/DAC integrated circuits. The design of digital sound filters allows to adjust more parameters and overcomes some of the constraints of analog systems. In this paper, we provide a short review of the Tomatis Method, the main functions of the Electronic Ear and we describe the designed system with comparison measurements to the analog one.

Improvement of symptoms in children with autism by TOMATIS training: a cross-sectional and longitudinal study

“…The TALKSUP device encompasses all the technological components employed in the TOMATIS approach. The TALKSUP device integrates all the technologies employed in the TOMATIS technique, encompassing the Electronic Ear (EE), comprising an amplifier, a filter, and an electronic gate, primarily designed to “filter the sound” [see details in the flowchart of the EE of Józwiak et al (2018) ].
