Nws hais tias cov suab amplitude (loudness) qhov sib txawv ntawm ob lub pob ntseg yog lub cue siv rau suab localization . Yog li, lub hlwb siv ob qho tib si cues localize suab qhov chaw. Piv txwv li, suab los ntawm tus hais lus yuav ncav cuag koj lub pob ntseg sab laug sai dua thiab nrov dua suab uas ncav cuag koj sab pob ntseg.
Ib yam li ntawd, tej zaum koj yuav nug, vim li cas lub suab thaj chaw tseem ceeb?
Localization yog muaj peev xwm qhia cov kev taw qhia ntawm a suab qhov chaw hauv 3-D qhov chaw. Muaj peev xwm localize suab muab kev mloog zoo dua qub thiab nyiam mloog. Nws kuj yog tseem ceeb rau qhov kev nyab xeeb xws li kom tsis txhob muaj tsheb thauj mus los, tus neeg caij tsheb kauj vab mus rau ntawm txoj kev khiav, lossis cov khoom poob.
Ib tug kuj yuav nug, dab tsi yog ob lub binaural auditory localization cues? Rau binaural cues , cov ntaub ntawv ntawm ob pob ntseg (microphones) yog xav tau. Lawv poob rau hauv ob Pawg: Interaural lub sij hawm sib txawv (ITDs) Interaural lub sij hawm sib txawv yog tshwm sim los ntawm qhov sib txawv propagation times a the suab yoj los ntawm qhov chaw mus rau ob lub pob ntseg.
Yog li ntawd, pob ntseg txiav txim siab li cas ntawm lub suab?
Lub wavelength. Thaum twg suab yog lub teeb treble suab (tshaj 1 kHz), lub wavelength plays lub luag haujlwm tseem ceeb rau lub hlwb hauv kev txiav txim tus suab taw qhia . Yog tias suab los ntawm a kev taw qhia mus rau sab xis ntawm lub ntsej muag, lub taub hau yuav tiv thaiv cov suab nthwv dej ntawm ncav mus rau sab laug pob ntseg.
Cov qauv twg pab peb ua suab nrov?
Sab Nrauv Pob Ntseg (Lwm cov txheej txheem kuj pab peb localize suab : cov no yuav tham tom qab.) Lub pob ntseg nqa suab mus rau lub pob ntseg, thiab nws cov hauv ob sab phlu tsim pob ntseg ciab kom lub pob ntseg thiab cov kwj dej kom qhuav tawm thiab txhawm rau cov av ua ntej nws mus rau lub pob ntseg.

Kuv tuaj yeem tshawb xyuas kuv lub suab lus ntawm kuv lub iPhone los ntawm lwm lub xov tooj li cas?
Hu rau koj lub iPhone thiab tos kom lub suab xa tuaj. Thaum lub sij hawm txais tos ua si, hu *, koj tus password email (koj tuaj yeem hloov nws hauv Chaw> Xov tooj), thiab tom qab ntawd #. Raws li koj tab tom mloog cov lus, koj muaj plaub txoj kev xaiv uas koj tuaj yeem ua tau txhua lub sijhawm: Tshem cov lus los ntawm nias 7
Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
Lub hom phiaj tseem ceeb ntawm lub suab ntsuas hauv suab hluav taws xob engineering yog dab tsi?
Sound-level meter, ntaus ntawv ntsuas qhov siv ntawm lub suab nrov, suab paj nruag, thiab lwm yam suab. Ib lub meter ib txwm muaj lub microphone rau khaws lub suab thiab hloov mus rau hauv lub teeb liab hluav taws xob, ua raws li hluav taws xob circuitry rau kev khiav hauj lwm ntawm cov teeb liab no kom cov yam ntxwv xav tau tuaj yeem ntsuas
Kuv yuav tshem tawm cov suab nrov tom qab ntawm lub suab li cas?
Tshem cov suab nrov tom qab koj tau kaw Xaiv qhov "tseem ceeb" ntu ntawm koj lub suab, qhov twg nws tsuas yog suab nrov xwb. Mus rau cov ntawv qhia zaub mov cuam tshuam thiab nyem Noise Tshem tawm. Nyem Tau Noise Profile. Xaiv tag nrho cov suab uas koj xav kom cov suab nrov tom qab tshem tawm. Mus rau cov ntawv qhia zaub mov cuam tshuam thiab nyem Noise Tshem tawm
Kuv yuav cais cov suab ntawm lub suab li cas?
Yog li ntawd, nws tseem ceeb dua los sim thiab phim qhov zoo ntawm ob qho tib si lem thiab ua kom lawv ua ntej koj cais cov suab. Qhib Audacity thiab Ntshuam ob qho tib si tsis tu ncua thiab instrumentaltracks. Xaiv ib qho ntawm cov lem thiab siv lub Sijhawm Hloov Cov cuab yeej los roughlyalign ob lem. Zoom hauv tiag tiag thiab ces zoom nyob rau hauv ntau
