<p>The invention aims at eliminating the drawback of electrical recordings by using another method for recording sounds comprising sound data sensitivity. The principle is to use the interface boundary of a tube between ambient air and the tube internal volume, which is the mouthpiece wherein the particles are stirred and by translation are reverberated on the walls of the tube and on the base. Capsules measuring air pressure variation translate the data into an electric signal. The volume can be produced in flexible or semirigid material. The mouthpiece principle enables to capture all the data indirectly but in a more sensitive and complete way. Said method provides a hypersensitive microphone with amplitude reduction, enabling to have all the data concentrated under one scale sampling of much reduced amplitude. The apparatus and the method are useful for everyone involved in the audio world and the sensitive recording in a single operation of aerial sound waves in very broad frequency ranges</p> |
