Description
Technical Field
The application relates to the field of indoor noise elimination equipment, in particular to indoor adjustable noise elimination equipment.
Background
Sound is generated by the vibration of an object, the propagation form of the vibration in an elastic medium is sound waves, and the sound waves in a certain frequency range (20-20000 Hz) act on human ears to generate the sound feeling. Noise is generally defined as "unwanted sound" and is an environmental phenomenon.
A person is exposed to a noisy environment for a lifetime, and noise is also an environmental pollutant generated by various activities of the human being. Vibration, which is the reciprocating periodic motion of an object (or a part of an object) along a straight line or a curve and passing through a balance position, is widely present in nature and engineering, and since vibration is a source of noise, the problem of noise can be effectively solved by solving the vibration.
Three noise reduction measures, namely noise reduction at the sound source, noise reduction during propagation, and noise reduction at the human ear, are generally employed for noise reduction, and are all passive. In order to actively cancel noise, the technique of "active noise cancellation" was invented. The principle is as follows: all sounds consist of a certain frequency spectrum which can be completely cancelled if a sound can be found which is exactly the same as the noise to be cancelled, but with exactly opposite phases (180 deg. apart). The key is how to get the sound that cancels the noise. The method actually adopted is as follows: starting from the noise source, the phase of the original noise is reversed through an electronic circuit. From this point of view, the technique of active silencing is actually "combating poison with poison".
