ABSTRACT


The aim of the research was to analyze anatomical bases for the effect of sound strengthening. Lenghts of the arm of the lever created by the auditory bones were also measured. The research was conducted on the temporal bones of 9 species of mammals: humans, Macaques, dogs, cats, American Minks, cattle, guinea pigs and rats. Twenty bones of each species were observed: 10 males and 10 females. The calculations were made with the use of a computer programme – Multi Scan. The research showed that carnivore (cats, Minks and dogs) had the best anatomical conditions for sound strengthening in the middle ear.

Key words: middle ear, measurements, strengthening of acoustic wave, mammals.
