Using sound recordings, they measured the duration, number and audio frequencies of chest beats made in the wild by silverback mountain gorillas monitored by the Dian Fossey Gorilla Fund in the Volcanoes National Park, Rwanda.

Researchers used audio frequencies to analyse the drumming sounds caused by chest beating in wild adult male silverback gorillas in Rwanda.

Morsy said the problem with just filtering out specific audio frequencies is that every song is different.
