A summary of the article is shown below:
This study examined whether auditory pitch and loudness affect the perception of object’s weight. Two series experiments showed that the object with High-Pitch sound was perceived as being lighter than the object with Low-Pitch sound and that the perceived weight was not affected by loudness. Because auditory pitch has a relationship to the weight of an object while loudness has a relationship to the distance of a placed object, the perceived weight was affected by auditory pitch not loudness. Given these results, perhaps sound effects may make it easier to carry heavy luggage?
