Classification of the sonorosTeniendo into account resources the two basic types of which we have spoken, we can classify the sound resources according to various aspects, some of which we mention below - by the technology used: analogue and digital-by the way produce is: live or recorded-by the nature of the sound: voice, original sound sources, music, noises and sounds generated technically-used brackets: does recording and reproduction: magnetic tape, magnetic tape to cassette, vinyl records, DCC, DAT, Mini Disc.? MD, CD DA, CD-r, CD-Rw, CD-ROM, DVD, card, computer audio, synthesizers, multimedia systems-by technical means: do live: microphone ( wired or wireless - foot table, hand, clamp or tie - ) speakers, intercoms, headphones, receivers for simultaneous translation, phone, players and amplifiers, sound, etc. are recording and reproduction: open reel tape recorder??, cassette player to tape (Deck ) DCC deck, deck, DAT, turntable, CD, reader reader/recorder / MD recorder, reader/engraver of CD ROM, DVD, video, mixer, effector, power amplifier, computer sound cards, computer applications, microphone, headphones, headphones, loudspeakers, acoustic screens, radio receivers, synthesizers, etc.USE teaching methods of the resources SONOROSLas didactic possibilities of sound and sound resources can analyze from three basic approaches. These are: do sound as recurso.¿sound as means of expression and communication. the sound as a critical analysis of the information.??Sound recursoEn this sense we refer to the use of the medium sound _tanto from the point of view of computer material, as material step by us mismos_ as a tool to use at different times of our performance. So we will serve him as motivational resource in the presentation of some issues - be it with original recordings, now with audio documents-, or as the way to complement some of our explanations and even as activity of synthesis to reinforce some concepts. Likewise our action recording can serve us self-assessment in order to improve it. Learn to play or improve the habit of listening can be one of the main objectives of use of this medium. To do so we can have simple exercises such as: find out how many times repeats certain word; identify different sounds; following a series of instructions; use the context of the speech explaining the meaning of unfamiliar words; reconstruct a story from misplaced sound effects; etc.Sound as means of expression and communication Comunicacionla as activity that allows the relationship between the people and for the exchange of information is shared by both education and media employing sound - radio, recordings, etc.. Communication is also the raison d ' être of the expression, because it is a natural need to communicate. To live is to express themselves, says Professor Siguan; and the expression is the expression of being in the world.Information technologies facilitate various forms of representation. Sound resources, to use various languages - verbal, musical, sound, etc. allow the elaboration of messages materialized in various forms of symbolic representation. In this way we can build a message and communicate it through multiple sounds, words, and effects. Sound resources are converted in a medium so each person can find their own form of representation.The use of the sound environment facilitates various forms of expression, understanding this as «the manifestation of thought processes that involve the ability of conceptualization and the acquisition of knowledge, motivated in turn by the multisensory perception and experience of each individual». (Moreno, 41 1998;. The expression is thus a creative process that starts mechanisms of transformation and search for new possibilities with the intention of communicating. This idea it expressed graphically in Figure No. 2.
