Ryan Cash has written one of the posts I’ve always wanted to publish some day.
Why are sounds of smartphones or computers always wrong in TV shows and movies?
One of the main characters, Andy, calls and leaves a voicemail for his mother using an iPhone 4 or 4S (couldn’t tell from looking at it). When he “hangs up his iPhone”, the phone makes a beep sound as he presses the “End” call button. This is doubly wrong – the iPhone doesn’t make any sound when hanging up a call, nor does it ever make this particular sound (or one like it) at any time.
I honestly have no idea why the TV and movie industry thinks it’s better to “fake” sounds. The only theory I have is that pictures shown on screen also need a sound feedback to communicate action.
Another thing that annoys me: when, during phone calls in TV shows or movies, the screen isn’t locked by the proximity sensor, indicating the call is, indeed, fake.
