Hypoacusis detector for evaluation of scholars in field

Hypoacusis on scholars has become not only a problem but also an indicator when attention disorders or misunderstood instructions from teachers are observed. A primary detection of hypoacusis, in particular in speech range, can help scholars, parents and teachers to improve or correct the learning process. A hypoacusis detector has been developed to be applied in field. This device is based on the generation of three tones and three sound level pressures in the speech range. Both the laboratory evaluation and a case of study results are reported in this document
