In this study, we try to give a new algorithm for detect hearing Loss patients using magnetic resonance images. It already has several solutions, but they are not suitable for practice. We use Wavelet Entropy (WE) and Cat Swarm Optimization (CSO) in proposed algorithm. In the final, we prove our algorithm in 5-fold Cross Validation. The overall accuracy of our method achieved 84.50± 0.81 [ABSTRACT FROM AUTHOR]

According to the World Health Organization (WHO), more than 1.1 billion people are currently at risk of losing their hearing due to excessive exposure to noise. Of this, a significant proportion consists of children, youth and young adults who are exposing themselves to excessive levels of sound through various leisure activities (music players, concerts, movies at the theatre, dance clubs, etc.). To address this issue, many approaches have been developed, ranging from general awareness messages to volume limiters on personal music players. Nevertheless, it seems that, as with all dangerous behaviors, the most promising approach is a direct one in which a personalized assessment of the risk has been made and the person is made aware of the associated detrimental consequences. The present paper describes a counseling approach whereby the sound exposure is associated with an increased loss of hearing sensitivity. The proposed “Age of Your Ears (AYE)” metric is computed using the ISO 1999 multiregression model and predicts for a given age and a given sound exposure the resulting accelerated aging of the person’s hearing. Preliminary results from pilot studies and focus groups with youths will be presented together with the underlying mathematical and statistical foundations. [ABSTRACT FROM AUTHOR]

The World Health Organization defines disabling hearing loss for children as having an average hearing threshold of >30 dB HL at 500, 1000, 2000, and 4000 in the better ear. In high income countries, however, a hearing loss for children is commonly defined as having an average of >20 dB HL in either ear. The purposes of this study were 1) to compare the prevalence of hearing loss in three countries using these two definitions of hearing loss, and 2) to examine the adequacy of using pure tone thresholds as an indication of hearing health care needs. A total of 1330 children in Brazil, Cambodia, and China participated in the study. Their outer, middle, and inner ear functions were assessed using otoscopy, tympanometry, and distortion-product otoacoustic emissions, respectively. If otoacoustic emissions of =6 signal-to-noise ratio were not present in 4 of the 6 test frequencies, a pure tone audiometry was administered. Results indicate that the WHO hearing loss criterion significantly underestimated the prevalence of hearing loss in these populations (i.e., overall = 6.7 times lower). When other ear and hearing disorders such as ear wax accumulation and middle ear problems are considered, however, the referral rate increased to 21%, 16.7%, and 10.6% in Brazil, Cambodia, and China, respectively. As children with minimal or unilateral hearing loss are negatively affected by hearing loss, hearing professionals in different countries are encouraged to adopt more stringent than WHO criteria to identify children with hearing loss and disorders. Additionally, hearing testing protocols should include the examination of outer, middle, and inner ear status, and interventions should be provided immediately following identification to minimize the negative effects of hearing loss on children's speech, language, cognitive, and social development.

The present work was inspired by the wish to contribute to the bilingual alphabetisation of deaf children whose mother tongue is Libras (Brazilian Sign Language). In this light, we came up with an internet environment to encourage deaf children to engage in informal conversations and, at a later stage, in educational activities (both oral and written). In order to create the environment, we first carried out extensive research as an essential methodological step, which then led to the establishment of three sets of requirements. These requirements gave rise to the possibilities offered by the system, as well as to its general interface and interaction solutions. Finally, we described the overall features of the technological tool proposed in the present paper. [ABSTRACT FROM AUTHOR]
