    2020-07-27


    Screening of new components At electrical level, these technological weaknesses can lead to modifications of the I=f(V) curve. For example, variations of the contact resistance in the flip chip assembly and in the wire bonds are likely to affect the series resistance of the device and traces of the soldering flux can create a leakage current associated with a modification of the parallel resistance. The upscreening flow was applied on two sets of ten components from each reference: 335 and 240nm.

    Introduction As many factors influence the language development outcomes of cochlear implant (CI) users, regular formal evaluations are necessary to monitor progress post-implantation. The standardized assessment materials used in such formal evaluations of speech perception skills are not widely available in Sinhalese, a language with more than 15 million speakers, the vast majority of whom live in Sri Lanka [1]. Most CI clinics in Sri Lanka resort to using informal translations of the available English assessment materials, e.g. the Common Object Token (COT) test, which is a closed-set test used for assessing the perceptual skills, auditory memory, and auditory-motor integration skills of paediatric CI users as young as 3 years old [2], [3]. The COT test was chosen for 133 2 into the Sinhalese language for the following reasons: (1) the COT test is useful for children who are able to complete closed set tasks but not quite ready for open set tests, (2) it is interesting for children (because it involves colourful toys), (3) it is suitable for use with children who have limited speech production skills (because it requires a motor response rather than a verbal response), and (4) it is suitable for assessing performance over time (due to demonstrated test/retest reliability) [2]. The current study had the following 3 aims:

    Results
    Discussion Western Europe, USA/Canada, and Australia have traditionally been the areas in which cochlear implantation is most common [9], [10]; correspondingly, the most common and well-known validated tests and (re)habilitation materials have been written in the native languages of these countries. The majority of children (and adults) with disabling hearing loss, however, are from developing countries [11], [12] and although only a small percentage of children in these countries have a CI, that small percentage still translates into a sizeable amount of children (e.g. [13], [14], [15]). While for some non-Western European languages, e.g. Mandarin Chinese, a range of tests exists [16], [17], [18], for many languages they do not. Audiologists working in such languages must instead rely on ad hoc translations. If, however, audiologists had accurate and validated translations of tests and materials in the native languages of their patients, they should be better able to assess and safeguard the language development. This is the context of the present study.
