Car audio test apparatuEst core tool ut qualis est car audio ratio. Et standardized operatio processus ensures quod test notitia est accurate et reliable, et praebet a scientific basis ad audio debugging et optimization.
Ante operationem, in apparatu calibration et environmental praeparatio fieri bene. First, place the test microphone in the standard listening position in the car (at the level of the driver's head), connect the audio analyzer and signal generator, and calibrate the equipment after turning on the power to ensure that the frequency response error is controlled within ±0.5dB. Test amet debet tacere (background sonitus ≤30db) et fenestras et aer Conditioner oportet clausus vitare externum.
Et core test gradus sunt ferri ex tribus gradibus. Primum est frequency responsum test. Et signum generantis outputs a 20hz-20khz et nihilo. In audio analyser records sonum pressura campester of speaker ad diversas frequentiis in ipsa tempore, generat frequency responsionem curvae, determinat utrum sit frequency cohortem vel apicem. Secundum est distortio test. A 1KHz Sine signo est input ad deprehendere totalis harmonica distortione (Thd). In THD de summus qualitas audio ratio oportet ≤0.5%. Ultima sonus agri positus elit. Multi-channel test signo lusit et sonus imago situ singulis orator colligitur per tortor ligula ordinata ut sonus agri accuratius focused sine offset aut overlap.
Data dispensando et analysis sunt key links. Post probationem perficitur, apparatu automatice generat fama continet parametri ut frequency responsio, distortione, et signum-ut-sonitus Ratio. Et technicae iudicare problema secundum curvam trend: si summus frequency cohortem ATTENUPATIO est obvious, in crosseter parametri opus esse adaequatum; Si admodum excedit vexillum, ut sit speaker unitas matching forsit. Quidam altus-finem apparatu subsidiis notitia collatio munus, quod potest comparari industria signa vel officinas parametri celeriter locate optimization directionem.
De mensuris operatio estCar audio test apparatuPotest comprehendendo evaluate et acousticus perficientur audio ratio, solvere problems de strepitu et tenebrarum sonus agri ex radix, adducere immersive auditiis experientia currus dominis, et quoque spondet qualis est currus audio R & D et productio.
