Abstract
Piedāvātais paņēmiens elektroakustisko izstarotāju skanējuma korekcijai paredz tādu testa signālu un to secības izvēli, kas ļauj gan identificēt katru no apskaņošanas kanāliem, gan katra mērījuma veikšanas vietu mērījumu plaknē bez mehānisku palīglīdzekļu izmantošanas un bez signāla savienojuma īstenošanas starp atskaņošanas un mērīšanas iekārtām. Amplitūdas-frekvenču līknes (AFR) korekcija tiek aprēķināta, ievērojot katra mērījuma svara koeficientu, kas ir atkarīgs no konkrētā mērījuma attāluma un leņķiskās novirzes no operatora norādīta punkta mērījumu plaknē.Piedāvātā iekārta paņēmiena realizēšanai papildus parastajiem apskaņošanas sistēmas optimizācijas moduļiem ietver: a) mērsignālu ģenerēšanas moduli, kas spēj ģenerēt specifiskus signālus izstarotāju identificēšanai un attālumu noteikšanai līdz tiem; b) balss sintēzes un vizualizācijas moduli, kas nodrošina iekārtas spēju veidot divpusēju komunikāciju un vadīt operatora darbības; d) laika sinhronizācijas un signāla laika aizturu analīzes moduli, kas nosaka mērmikrofona atrašanos mērījumu plaknē; e) AFR analīzes moduli, kas veic līknes korekcijas, ņemot vērā katra mērījuma svara koeficientus, un spēj veikt specifiskas korekcijas, piem., ietverot vai neietverot īpaši agrīnos signāla atstarojumus nomērītajos akustiskajos datos.The proposed technique for correcting the sound of electro-acoustic emitters provides for the selection of test signals and their sequences that allow both the identification of each of the sound channels and the location of each measurement in the measurement plane without the use of mechanical aids and without the implementation of a signal connection between the playback and measuring devices. The Amplitude-Frequency Curve (AFR) correction is calculated by taking into account the weighting of each measurement, which depends on the distance of the particular measurement and the angular deviation from the point indicated by the operator in the measurement plane. The offered equipment for the technique in addition to the usual sound system optimization modules includes: a) measuring signal generation a module capable of generating specific signals for identifying and detecting distances to radiators; (b) a module for voice synthesis and visualization that provides the facility with the ability to communicate bilaterally and manage operator activities; (d) a time synchronization and time delay analysis module that determines the position of the measuring microphone in the measurement plane; (e) A AFR analysis module that performs curve adjustments taking into account the weighting factors of each measurement and is capable of making specific adjustments, eg including or not including particularly early signal reflections in the measured acoustic data.
