The sounds you use in your presentations should be “invisible”. They should compliment the visual elements without taking away from them. Your audience shouldn’t be overly aware of the sounds, but they should feel their effects.
Due to movies like “Jaws”, the modern audience has become aware of music that tries to “Mickey mouse” its way through the movie – in other words – tries to be relevant to the actions of the characters. The modern audience is more discerning, and a more subtle approach is needed.
However, this doesn’t stop many sound effects clichés still having a place in today’s production. What affected someone emotionally in the 50s, is likely to still have the same effect today. It is just the style, however, that has changed.
