So maybe we trash our cellphones out of simple frustration. Comes a study that says nearly a quarter of U.S. and European wireless calls have bad sound quality. Granted, the audit was conducted by a company with a vested interest—Ditech Networks sells "voice-quality products" to the communications business—but we all know the frequent frustration of shoddy sound on cellphones.
It could be worse. In faster-growing markets like India and South America, about 60 percent of calls suffer from bad sound, Ditech says.
