Resumo-Implantes cocleares (IC) são dispositivos eletrônicos implantáveis que têm como finalidade a restauração da audição em pessoas com perda auditiva profunda. Este trabalho apresenta uma comparação entre duas estratégias de redução de ruído para IC. É analisado o caso de um arranjo de microfones sujeito à técnica de conformação de feixe baseada no método de variação mínima com resposta sem distorção e uma modificação, na qual é preservada apenas a potência da fala de interesse. Simulações computacionais associadas a critérios objetivos indicam que a técnica de preservação da potência resulta em maior inteligibilidade e redução de ruído, mostrando-se mais apropriada para IC.

This paper presents a new structure for hearing aids. Normally, the power consumption and user experience are contradictory. The proposed hearing aid structure mainly consists of three parts: the earpieces, the mobile computing platform, and the real-time speech-enhancement application. It can run complex algorithms without carrying out heavy calculations on the processors in the hearing aid. Thus, the binaural algorithm is utilized without being limited by complexity and power consumption to improve the user experience. Moreover, the speech-enhancement algorithm can be updated much more easily than in traditional built-in digital signal process hearing aids. A good level of user experience is achieved by combining the hearing aid and mobile computing platform with a 400-MHz transceiver; furthermore, the 400-MHz transceiver can reduce path loss around the body. The concept verification process showed that the overall usage of the central processing unit in the smartphone is around 16%, the signal-to-noise ratios show at least a 30% improvement in some environments, and the whole system delay is 8.8 ms. The presented objective and subjective results show significant improvements regarding user experience and usability brought about by the proposed structure.

At present, digital technologies can serve as new tools for acoustic measurements of sound pressure levels, since affordable means such as smartphones are available. In order to understand the accuracy and reliability of measurements using an android application, in this paper we will investigate the comparison between laboratory measurements developed with traditional sound level meters and 4 different mobile phones. The study includes building acoustics tests on a timber cross laminated slab, featuring a floating floor.
