In teaching, visual perception and auditory perception are the two main sources of students' cognition and understanding of teaching content. With the increasing popularity of information-based teaching equipment such as teaching touch all-in-one machine (commonly known as interactive intelligent tablet) in the stage of basic education, the teaching content is increasing from teachers' blackboard writing to multimedia materials such as graphics and images, which greatly enriches the source of students' visual perception. At the same time, how to create a better auditory environment for the teaching environment has also attracted more and more attention in the industry.
This problem is mainly reflected in two aspects: one is how to better protect and play the voice of teachers; Second, how can multimedia sound effects be better guaranteed. Teachers have been teaching hard for a long time, and they often use their voices excessively due to the high frequency and volume of lectures; In the large classroom teaching environment, the teacher's voice sometimes cannot be clearly transmitted to every corner. This not only leads to the decline of teaching efficiency and the unsatisfactory absorption effect of students, but also directly relates to the health and voice protection of teachers. In recent years, microphones, "little bee" and other public address equipment have gradually appeared in the classroom to reduce the burden on teachers and help convey information more in place, but problems such as uneven quality of public address equipment and Howling also occur from time to time.
On the other hand, the rich forms of multimedia make the classroom more lively and interesting. By playing audio and video files, all kinds of "sounds" are input into the classroom, which also makes the presentation of knowledge separate from the single carrier of books, and the educational model more dimensional. However, multimedia playback sound effects are highly dependent on equipment. At present, the sound effects of most teaching products are still far from the real high fidelity level.
These two problems are directly related to the quality of teaching and learning. As an important carrier of information-based teaching, the interactive intelligent tablet industry attaches great importance to "teaching voice" and studies it as an important part of the overall solution of intelligent teaching. In the industry, the leading brand touch shows a new breakthrough of its intelligent teaching overall solution to the "voice of education".
