Maswali ya Kutengeneza Beamform na Mikusanyiko ya Maikrofoni

Kagua ucheleweshaji wa safu, jiometri ya uendeshaji, vikwazo vya MVDR, na vikomo vya nafasi ambavyo vinaunda upigaji sauti wa mwelekeo katika mazingira ya sauti ya kelele.

Hakiki kila swali8 maswali

Majibu na maelezo huonekana unapojibu maswali.

  1. Je, uundaji wa mng'aro unatumia ishara gani hasa?
    • Tofauti za wakati/awamu za kuwasili kwenye maikrofoni nyingi
    • Rangi ya chanzo cha sauti
    • Kiwango cha betri ya kifaa
    • Joto la chumba
  2. Je, mbinu rahisi zaidi ya kuangazia inaitwaje?
    • Kukunja nne zaidi
    • Kuchelewa-na-jumla
    • Ufungaji wa spectral
    • Ufuatiliaji wa lami
  3. What is the defining constraint in an MVDR beamformer?
    • Maximize every incoming direction equally
    • Remove the desired source before summation
    • Preserve the desired target response while minimizing output power
    • Convert the microphone signals into text
  4. Uwekaji mwanga unahusiana vipi na ukandamizaji wa kelele ya kipaza sauti moja?
    • Inaibadilisha kikamilifu na kuifanya kuwa ya kizamani
    • Inafanana nayo
    • Inafanya kazi tu bila usindikaji mwingine wowote
    • Inaikamilisha kwa kuongeza maelezo ya anga ambayo maikrofoni moja inakosa
  5. Why can microphone spacing that is too large create spatial aliasing?
    • Different directions can produce indistinguishable sampled phase differences at a frequency
    • The microphones stop recording sound
    • The sample rate automatically drops to zero
    • The array loses all time information
  6. 'Neural beamforming' ni nini?
    • Ubunifu hufanywa kwa mkono kabisa
    • Kuchanganya mitandao ya kina (k.m., makadirio ya barakoa au mwelekeo) na boriti ya anga
    • Inaondoa maikrofoni zote
    • Aina ya kibadilisha sauti cha kituo kimoja
  7. What can happen when an MVDR beamformer’s assumed steering vector is inaccurate?
    • The array automatically gains microphones
    • The audio changes into a spectrogram image
    • Its target preservation or interference suppression can degrade
    • The desired source is always amplified without limit
  8. What information determines the steering delays for a chosen look direction?
    • Audio file format and transcript length
    • Speaker age and language
    • The number of model parameters alone
    • Target direction, microphone geometry, and speed of sound
