Presentation Transcript

  1. Localization • What are some problems or limitations?

  2. Localization • Low frequency sounds aren’t attenuated by head shadow Sound is the same SPL at both ears Left Ear Right Ear Compression Waves

  3. Localization • High frequency sounds have ambiguous phase lag Left Ear Left Ear Right Ear Right Ear Two locations, same phase information!

  4. Localization • These cues only provide azimuth (left/right) angle, not altitude (up/down) and not distance Left Ear Right Ear Azimuth

  5. Localization Additional cues:

  6. Localization Additional cues: Head Related Transfer Function: Pinnae modify the frequency components differently depending on sound location

  7. Localization Additional cues: Room Echoes: For each sound, there are 6 “copies” (in a simple rectanguluar room!). Different arrival times of these copies provide cues to location of sound relative to the acoustic space

  8. Localization • What would be the “worst case” scenario for localizing a sound?
