what the young enthusiastic mouse knew... facts about product sounds
sound is the property of a product
(often) not the entity itself
it is the combination of product properties that
determine the concept of a product
consequently, how people appraise a product
and attribute meaning to it
there are perceptually different categories of
product sounds
product sounds belong to a network of
conceptual associations
different sounds categories evoke different
conceptual associations
