Fones de Ouvido: aumentam mortes de pedestres desatentos

Por Paul Resnikoff, traduzido por Nacho Belgrande

Esqueça sobre os danos que os fones de ouvido causam à audição. Porque de acordo com um novo estudo, há outro problema: morte súbita e irreversível. Na verdade, o número de mortes e acidentes fatais envolvendo pedestres usando fones de ouvido TRIPLICOU ao longo dos últimos anos, de acordo com o que se concluiu do estudo. Tais acidentes, frequentemente repentinos e fatais, geralmente envolvem homens jovens «media de idade de 21 anos» andando por áreas urbanas.

Não falamos de trancos ou finas, das quais há muitas. Trata-se de morte e ferimentos graves, que se multiplicaram de cerca de 16 em 2004 nos EUA para 47 em 2011. No total, o grupo de pesquisa encontrou 116 casos documentados de morte e ferimentos graves desde 2004, com 70 por cento dos casos levando a óbito.

Carros são um problema típico, apesar de que, estranhamente, mais da metade dos acidentes envolveu pessoas sendo atropeladas por trens – ou sejam apesar de alarmes altos e outros avisos em muitos casos, a música estava num volume tão alto que não se percebia mais nada auricularmente no momento da batida.

Não precisa ser nem um PhD para saber que o uso de fones de ouvido tende a criar uma desconexão do mundo. Os pesquisadores chamaram o fenômeno de ‘cegueira desatenta’, enquanto destacaram que a audição – e não somente a visão – desempenha um papel fundamental na percepção de estímulos externos e para evitar problemas.

O estudo foi conduzido pela revista científica britânica Injury Prevention, com Richard Lichenstein do Maryland Hospital for Children encabeçando a equipe. Os pesquisadores analisaram diversas fontes para criar a estimativa, incluindo o National Electronic Injury Surveillance System, o US Consumer Product Safety Commission, Google News Archives e o Westlaw.

While the effects of antenna polarization may be interpreted as a reduction in the quality of some radio links, some radio designers often make use of this property to tune an antenna to their needs by restricting transmission or reception to signals on a limited number of vectors. Even today, I go big game hunting and all this, and the more dangerous something is, the happier I am.

  2. Rather,all the applications keep running in the
    background although in a low power state,utilizing both processing power and memory that leads to a lower battery life.
    If you don't want to use Safari to navigate to pages, zoom in, and read articles, Byline may be just the app for you. Double Tap (Tap the home button twice > Press down on an app for one second > Hit the "minus" button on all apps that are running) When you open an app, it stays running until you actually turn it off.

  4. You can learn about those fundamental lessons by
    simply playing video games. When children fit these fun
    video game titles into actions require time to view those facial seems to be and human body expressions.
    I'm not against such games, but it never hurts to have alternatives in case one doesn't want their child
    playing those kinds of games or maybe just would rather their kid
    be exposed to other types of gaming than the simple "shoot, run, shoot" types of games that are so popular.
