DEVICE FOR MEASURING THE ACOUSTIC POWER OF A NOISE SOURCE WITH EXCELLENT MEASUREMENT ACCURACY
The present invention refers to a charger acoustic won noise relates to device. Generate a device for the various kinds of electronics for or electrical device or machine (hereinafter, noise won (Noise source)), or the like, that has noise of present state includes data from a relationship should meet testing can cause approval from engine. the type of for testing noise which having, thereof in one example, a cover for portable every point surrounding the noise source (sound pressure) power acoustic bar the averaging of measurement test (sound power). Said acoustic power measurement of the that are important in the, a microphone relative noise source is accuracy of position and orientation. A microphone source noise precisely direction of the relative positions of a cover for portable every point and are to be held in the closed state of. since. A disk is other around the won separated's just not even. Therefore, said acoustic power measuring test for anechoic chamber preferably from undergoing. State of the SP heads and, acoustic power measurement test apparatus of the existing method, most anechoic chamber table is formed for testing but by virtue of its being free from dedicated device, such as a microphone the relative position of the noise source is provided to swiftly and correctly setting could not be applied to. The conventional system also 1 and Figure 2 shows a acoustic power measurement won noise and decides to explain the. plane from the. Also Figure 2 shows a simplified planar forms said of Figure 1 illustrated the.. An engine, and the engine is shown in the, horizontal of ground-(11) or a voice guidance service of a placed on the (13) on or detaching is formed from won (A) noise, said noise won (A) of around which a plurality of microphone (17) is so positioned as to. said respective microphones (17) the, tripod (15) are supported on noise state noise be apart from the plate is spaced from won (A) won (A) is directed, won (A). accept noise from the noise. Said microphone (17) and input into the of noise as much as this time, the signal transmitting line after replaced with one another over a current voice (17a) of outside through the computer-is transmitted. Computer a signal transmission line (17a) on the basis of information determined through said noise if not won (A) calculates the power at the bottom of the pillow includes. State of the SP heads and, said acoustic power measurement won a device of the existing method noise, noise won (A) to a microphone (17) by a specific program establishment of the altitude of the direction must manually server determines whether the. problem is that an. I.e. each tripod (15) microphone (17) to the inside of a wafer/to, tripod (15) a uncomfortably after surrounding sound source of moves, microphone (17) and controlling the height of, adjusts height a microphone (17) of selectively replaced with another by the sorts omni angle must the recording operation. an absentee ID stored by operating an. Through process of the approximately setting reaches a rear, two driving cams, a microphone source noise the constant the relative position of the, self measuring is arranged secure accuracy in CD capable of expressing traffic information whose reliability. very low.

Said hub disk (25) has door 5 the rotatable lever is rotated when the shown in the peripheral portion of the slit side surface thickness (25b) each support has (23c) fixed receiving top end of the. Furthermore, said support (23c) on an upper end section of the upper ring (23f) top elid processing device is provided with. Said upper ring (23f) each support (23c) and which are welded to the support (23c) the interval. In addition said your ring which is (23b) guide piece (23d) .are fixed. Said guide piece (23d) your ring which is as of layer plated at steel plate of a triangle (23b) the circumferential edge part of the sensor 1 is fixed to the retainer. Said guide piece (23d) a X-Y Cartesian the frames on an air assembly (23) is intended to by positioning a. I.e. said pointer (27) using the frame assembly (23) and then the putter is the origin of the I-a coordinate said X-Y center of said guide piece (23d) mounted on the axis Y shaft or X of won (A) noise for that frame relative to the assembly (23) relative positions of the recording operation. the support mount. Said each support (23c) of the extended end hub disk (25) is provided with. Said hub disk (25) each disk having a thickness constant support (23c) of fixed collected an extended end. To this end said hub disk (25) on the outer circumferential surface of an side slit (25b) is provided. Said side slit (25b) the hub disk (25), extends around a circumference of constant width and depth each support of as recesses (23c) fixed receiving top end of the. In addition said hub disk (25) hole provided at a center portion of a vehicle (25a) is formed. Said mounting holes (25a) passed through a through hole a vertically extending the normal a pointer (27) for receiving a. Said pointer (27) has an Image of the laser pointer as directing light onto the lower. Said pointer (27) irradiated from the light the ground (11) upon arrival at the center point to provide references make role of (S). On the other hand, also the rotatable lever is rotated when the shown in 4, said frame assembly (23) the 3 unit frame (24) partitioned into a, said hub disk (25) of a lower end unit frame (24) sensor 1 is fixed to the retainer. Is also to time as large as that of to illustrate the through 4. Said frame assembly (23) in, substantially all support (23c) microphone (17) is located a. said respective microphones (17) position control nine (31) through the intermediary of either a support (23c) being disposed at the point of needs of.. said respective microphones (17) is directed to surround this silencer won (A).. With reference to said microphone (17) the two unit 10 is mounted. Said microphone (17) of mounting position is refers to through Figure 7. Also shown in Figure 4 shows a frame assembly 3 also said (23) decomposition of is perspective view. The rotatable lever is rotated when the shown, said frame assembly (23) the 3 unit frame (24) consists of in. I.e., said unit frame (24) is coupled also 3 takes the form of hemi shown in the recording operation.. Said each unit frame (24) configuration, and the identical to each other and the.. Said each unit frame (24) based on the range the center point (S) is divided into 120 degrees, each unit frame (24) in outer (23a) your ring which is and (23b). takes the form of the partial arc. A gate electrode connected unit frame (24) support in (23c) the 5 130,140 are arranged. Said support (23c) sensing humidity number of. member is inserted and fixed. While, each said unit frame (24) lower end of one side of a piece the 47a (23g) there is formed a, opposite a groove (23k) is formed. Said home (23k) the neighboring unit frame (24) of 47a (23g) is 21 and 31 are nipped by. Thus said unit frame (24) assembly of the when said 47a (23g) with a neighbor the home scale of the unit frame (23k) each in the opposite direction to the insertion unit frame (24) is can be while the pre-assembled state. Also Figure 5 shows a acoustic shown in the 3 also said device is to display partial enlarged perspective view of a charger. With a drawing, said hub disk (25) at the center of pointer (27) is connected vertically constitution: a, hub disk (25) formed on the outer circumference of a side slit (25b) each support (23c) are insertion fixing end extension of can be viewed. In particular said each unit frame (24) between the fixing clip (29) is located a. Said fixing clip (29) as a part having an elastic tightening power, , neighboring the unit frame (24) support (23c) is filled to corresponding support (23c) has fixed on the handle body groove by. Said fixing clip (29) a supporting stand and (23c) when a separated from unit frame (24) the technique to resolve the. member is inserted and fixed. Said fixing clip according to embodiment (29) instead of an other strapping means to be capable of application to. member is inserted and fixed.
