The widespread use of mobile phones has already made a habit of listening to personal problems of passengers, or simply people who are near. In some countries the government tries to deal with people who talk too loudly on the phone, or prohibit the use of mobile phones in the transport or public places. In other countries they put “phone booths” for talking on mobile phone. But what if they have limited talking time on mobile phones and users do not follow the rules? Just muffle the signal.
Portable muffler of signals works with all types of signals: GSM, DCS, PCS, PHS, DECT, CDMA, and even 3G. Operating range is up to 10 meters. Battery life is up to 1,5 hours. It can be carried in any pocket (5,8 x 11,8 x 2,2 cm).
But the opportunity to stay in silence is not cheap. The gadget is sold online for $246.
