Abstract
The utility model provides a sound source positioning and visualizing system based on a microphone array. The sound source positioning and visualizing system is characterized by comprising a computer system connected in series with a sound collecting device. The sound collecting device is connected with the microphone array, which consists of at least three microphones. The sound source positioning system based on the microphone array overcomes limitation of a single microphone sound source positioning system in prior arts. The microphone array of the sound source positioning system has the advantages of strong spatial selectivity and noise suppression and obviation of manual movement, so that any spatial sound sources can be positioned.
Description
Technical field
The utility model relates to a kind of auditory localization and visualization system.
Background technology
Noise pollution is with water pollution, atmospheric pollution, noxious waste pollution and be called four and pollute greatly, and therefore controlling noise has become worldwide academic problem, is also more and more paid close attention to.Going into the hand control noise from the sound source aspect is more direct valid approach.
Sound has brought convenience to people, has enriched people's life.And confirm that the position of sound source in the space is the research that wide application background is arranged, it all has a wide range of applications in fields such as civilian, industry and military affairs.
Traditional sonic location system is to use single microphone to gather the equipment of sound, being limited in scope of pickup, and the signal to noise ratio (S/N ratio) of the signal that microphone is accepted is low, and the quality of pickoff signals is low.Therefore, there is not a kind of good sonic location system accurately to locate and visual demonstration at present to sound source.
Summary of the invention
The purpose of the utility model provides a kind of can accurately the location and the device of visualization display sound source.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of auditory localization and visualization system based on microphone array; It is characterized in that: comprise computer system; Computer system series connection sound collection equipment, sound collection equipment links to each other with the microphone array of being made up of at least three microphones.
Preferably, said microphone array is made up of four microphones, and four microphones are space quaternary pin and distribute.
The system of a kind of auditory localization based on microphone array that the utility model provides has overcome the limitation of traditional single microphone sonic location system; And the microphone array spatial selectivity of this sonic location system is strong, inhibition noise ability is strong and need not the artificial advantage that moves, thereby realized any sound source in space is positioned.
Description of drawings
The system schematic of a kind of auditory localization based on microphone array that Fig. 1 provides for the utility model;
Fig. 2 is the synoptic diagram of microphone array.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, the system of a kind of auditory localization based on microphone array that provides for the utility model comprises computer system, the sound collection equipment of computer system series connection, the microphone array equipment that sound collection equipment connects.Wherein, microphone array equipment is made up of four microphones, and it is as shown in Figure 2 to be respectively microphone T1, microphone T2, microphone T3 and microphone T4., and these four microphones are space quaternary card clothing and put.
When computer system is sent user instruction; This instruction is by the sound collection card receiver; The sound collection card is gathered voice signal through microphone array according to the user instruction that receives; Then the signal that collects is fed back to computer system again, the data that collect are handled by computer system.
The corresponding software of in computer system, packing into, can be on computer screen display control panel, through the frequency that this control panel can be regulated collection arbitrarily, the port number of collection.The data that collect can be carried out curve display, and X-Y scheme shows that three-dimensional picture shows, also can show with colored intensity map.Directly click the display mode that selector button corresponding on the panel just can provide the user to need, thereby known the position of sound source.Operate very convenient, succinct, understandable.
Software can also calculate the distribution situation of all sound sources through the strength of sound source of detected point, and shows through image, thus very the image expression the position of different sound sources, the position of sound source has also showed like visual like this.Software section also provides corresponding help file, and the user can directly click and check help.
Claims (2)
1. auditory localization and visualization system based on a microphone array is characterized in that: comprise computer system, and computer system series connection sound collection equipment, sound collection equipment links to each other with the microphone array of being made up of at least three microphones.
2. a kind of auditory localization and visualization system as claimed in claim 1 based on microphone array, it is characterized in that: said microphone array is made up of four microphones, and four microphones are space quaternary pin and distribute.
