1. An acoustic apparatus comprising:
a housing portion including an upper portion and a lower portion;
a transducer mounted adjacent the lower portion;
a first microphone mounted adjacent the lower portion;
an electrical connector configured to be connected to a computing device;
the electrical connector being electrically connected to the first microphone; and
wherein when the acoustic apparatus is placed against a floor and the transducer is activated, the transducer generates sound waves comprising a plurality of frequencies that are generated above, directed into, and travel through the floor generating filtered sound waves that can be detected by the first microphone and wherein based on stored sound wave profile information about different types of flooring material and a first amplitude of each frequency in the sound waves transmitted by the transducer into the floor and a second amplitude of each frequency in the filtered sounds waves the acoustic apparatus determines a composition of the floor.
