This is a trend I’ve noticed, mostly whilst working in the Library.
I’ve seen people talking on a mobile phone, and actually move the phone away from their ear and in front of their mouths when they speak. I don’t quite understand what the point of this is – and it kinda spits in the face of telecoms engineers that made the GSM system full-duplex. They are intentionally limiting their phones to half-duplex (i.e. you can either talk or listen, not both at the same time). Also, mobile phones are designed such that the microphone is in the right place to pick up your speech at a sensible level when the phone is held to your ear. Putting it right up against your lips just makes your voice overly loud and makes the signal clip – even when you’re speaking quietly. Phones have compressers and limiters in them such that your voice is intelligible, regardless of how loudly you’re speaking.
The other odd thing is that I’ve only ever seen black people doing this. Not once have I seen any other ethnicity doing this – which in itself is disturbing (just describing it makes me sound racist).
Most perplexing.
