Drumstick material and rebound characteristics
The hypothesis that the wooden drumsticks will produce higher rebounds has proven to be true.
In the past, drumsticks were differentiated according to how they were used in orchestra, band and street marching. However, this differentation has faded away because of the wide variety of drumsticks available today. A particular type of drumstick may produce a particular sound. However, drumsticks made from wood are still preferred because they can be used to produce many types of sound. Those made from fiber or metal are more durable. However, they tend to produce more shock/vibration and hence are a slightly more strenuos on the drummer's wrists.
One can alter this experiment by using weights of different weights, different types of drums, and drumsticks that are made of different thickness.
