Modern manufacturing technology has given audio a brand-new life, and all kinds of audio, from small and exquisite equipment that can be put into your pocket to equipment that can only be pulled by a few trucks, emerge one after another. For example: mobile phone stereo, mini speaker, U disk radio stereo, bookshelf stereo, floor-standing stereo, home theater, surround sound, karaoke stereo, square stereo, stage stereo, conference stereo, hotel, bookstore stereo, bar stereo and so on. Remember, a sound can be called acoustics, and its acoustics should have three elements: timbre, tone and loudness.
Everything should be people-oriented, and audio is no exception. From the perspective of human needs, acoustics can be divided into: personal acoustics; Home audio; Apply three categories of audio. Personal stereos and home stereos are more common and may be easier to understand. The application of audio is professional and not widely used, so it is a bit strange. This is also the reason why this article should focus on it.
Applied acoustics is acoustics applied in public places. Including: square acoustics, square dance speakers, karaoke acoustics, conference acoustics, stage acoustics, shop acoustics and so on. What's the difference between this stereo? How to distinguish? Just say what is the difference between square sound and square dance sound, and how to distinguish it. The main feature of square acoustics is that it needs a large environment. For example, the military parade in Tiananmen Square and the soldiers lined up from the rostrum to the street all need acoustics. This is a huge acoustic project. Another example is morning exercises on campus, which can be heard by hundreds of students. So, what about the sound of square dance? She is a team, and a few, dozens or hundreds of people can hear the sound. It is obviously distinguished by the size of space and the number of people. Therefore, the difference between square acoustics and square acoustics, in terms of required power, square acoustics is high power, while square acoustics is low power. From the control point of view, the sound of the square is controlled by professionals, while the sound of the square dance is controlled by everyone.
In this way, a conclusion is drawn that the method to distinguish sound is the size of the environment, the size of the power, and the difficulty of control. This is one of the ways to distinguish. Secondly, the use of function is also an important means of distinction. Take square acoustics and square dance acoustics as examples. Square acoustics, people need to play background music before entering the venue, and sometimes there are sub-venues, which need sound synchronization. The host can use wired microphone, while the chief inspector needs wireless microphone. Soldiers' answers need feedback, audience cheers need to be added, singers' songs need to be set off (synchronized synthesis), and so on. It needs the cooperation of directors from all sides and the guidance of the general control room to successfully complete the sound reinforcement, pickup, synchronization, synthesis and editing of the square. There is also the sound of square dance. It can be said that she is simple, as long as she can play music or speech or karaoke. The function is very different. As a result, the difference in investment price is derived.
As can be seen from the above example, the applied audio can be distinguished from five aspects: 1. Differences in application environment; 2. Differences in strength; 3. The difference between difficulty and control; 4. How many functional differences are there; 5. Price difference.
